Take our Kids to Work Day returns

 
After a two year hiatus, Take our Kids to Work Day returned to ESF on April 28. Kids 8-11 years old with an adult that works or studies at ESF explored ESF fostered-careers through their own class day:

  • ESF Sustainability: Which uses the least energy? A laptop, fan, or LED desk lamp? ESF’s new Energy Manager (and alum) Michael Amadori measured the electricity required to use all these household items.  Kids also played Wasketball, sorting common household waste into trash and recycling and used (with supervision!) solar power as a campfire starter.  They also had a sneek peak at our in-house power station.
  • Color changing chemistry! Chemistry’s Kate Bailie (and graduate student assistants) helped students with simple acid-base reactions; use salt water, aluminum foil, and a complete circuit to create a temporary “ink”, and assembled teeny temperature sensitive LCDs
  • All about Maple.  Which maples for syrup? (Any, but sugar has the best yield) What do the buds look like? The inside of a tree? With alumna Jill Rahn of ESF Forest Properties. 
  • Something's Fishy: tracing mercury.  Details are important in science! What can we measure? Kids received instructions, and then helped Environmental Biology faculty member, Environmental Toxicologist Dr. Roxanne Razavi and grad students Abby Webster and Mike Ackland with record keeping, measured length and weight of whole yellow perch and (with careful supervision) retrieved otoliths (tiny ear bones that can be used to age the fish, much like rings in a tree), eye lenses, and a piece of dorsal fin.  These fish are part of an ongoing study, Project Breathless.  The samples, along with many others, will be assessed by grad students and faculty to help trace mercury through the sample population’s habitat.  Kids and volunteers thought yellow wasn’t an apt description, and that they should be called apricot perch.  A few Kids thought this the grossest of the activities, but others really enjoyed being part of active research!
  • In the Lego® Bridge Challenge, Kids were tasked with planning (on paper) and then building (with Lego®) wide enough for Thomas the Tank Engine™ (or friend) to use, and allow 2 matchbox™ car wide lanes beneath. How much weight can it support? How few bricks can you use? (More bricks=higher materials and labor cost). With ESF Environmental Resources Engineering’s Karen Karker (planning support by Lindi Quackenbush).
  • Building an Urban Ecosystem.  What are the components of a park (or community garden)? Kids working on the park explain their choices to ESF grad student and Open Academy staff members Dan Collins and Maura Harling Stefl. Through this, they realized park spaces will be hot. So they added a snack shack, water stations and shade. These introduce a new challenge: how to deal with the trash?
  • Chemistry students David Spector and John Pezzulo ended the day with a Super Cool “Cooking” Demo, emphasizing safe handling of liquid nitrogen. While Kids (and volunteers) enjoyed some of the best strawberry and vanilla ice cream (served in low-waste waffle cone bowls) ever, John shared a secret:  that if really like what you are learning, and work hard, colleges might pay them to continue learning about that field through graduate school stipends and tuition waivers, and work in support of teaching and/or research.  
Kids Day is one of the earliest, and most enduring, programs of ESF's Women's Caucus. For a photo journey of the day, visit https://www.facebook.com/ESFKidsDay/; for information about past programs, please visit https://www.esf.edu/womenscaucus/kids.htm.

ESF alumnae talk about their experiences in STEM careers

In recognition and celebration of Women’s History Month, four alumnae discussed their unique experiences in pursuing STEM careers in a panel facilitated by Debbie Caviness, Director of SUNY ESF Alumni Relations, on Wednesday, March 23, 2022. The panel addressed many topics, such as the stereotypes women face in STEM careers, negotiating salaries, networking, and what the female experience of working in male-dominated STEM fields was like. The ESF Alumni Association, Office of Admissions, Office of Career Services, and ESF Women’s Caucus jointly sponsored this panel.

Christina Chan ’10, spoke about her experiences as both a female and a person of color as the owner and farmer of the Choy Division, a diversified 1-acre urban farm with a focus on east Asian crops and herbs. As a farmer in a field that is predominantly comprised of older white men, Chan felt insecurities due to being both a person of color and female. Starting out in her field, Chan braced for the worst and felt she needed to prove herself to other farmers, but over time began to realize that other people’s expectations don’t dictate an individual’s self-worth. Optimistically, Chan notes younger generations of farmers are becoming more diverse compared to their older generation counterparts. 

Kelley Corbine ’15, M'17, a forester with the US Forest Service (USFS) and wildland firefighter, faced similar experiences to Chan. In her work as a USFS forester, Corbine observes about 95% of the time in her work, she is the only female in the room. Like Chan, Corbine also felt the need to prove herself to male counterparts. As Corbine continued working, she realized she needed to treat herself kindly and reaffirm to herself that she deserved to be working with the USFS.

Keelin Gangwish ’19, a Pulp & Power Front Line Leader at the paper mill company Sylvamo, had a different challenge, as she works with people of diverse academic and social backgrounds. As a result of this, it was difficult for her to gain basic respect from her coworkers as a female worker. Gangwish recommends individuals to stand their ground, and to know their audience when it comes to addressing female stereotypes in the workplace. She also suggests to subtly guide other male coworkers to a desired outcome if they do not listen to advice. 

Gina Hale ’04, the Senior Director of Operations & Safety at Tufts Medical Center, advised others to ask questions and remain headstrong in topics individuals are confident in. Hale recounted a story of how she had to ask about flow dynamics to ensure the safety of a facility, demonstrating how it is acceptable to not know the answers to everything. In terms of salary negotiation, Hale advises others to not be afraid to ask how much other people make, and to use social networks to determine how much an individual should be making. 

Christina Chan received her B.S. in Environmental Science (focus on Health & the Environment) from SUNY ESF in 2010, and her M.S. in Conservation Science from the Imperial College London in 2013. Kelley Corbine received her B.S. in Natural Resource Management in 2015 and her M.S. in Forest and Natural Resources Management in 2017 from SUNY ESF. Keelin Gangwish received her B.A.Sc. in Paper Engineering in 2019 from SUNY ESF. Gina Hale received her B.S. in Chemistry in 2004.

Nutrient Cycling, Storm water runoff, and Communicating Science to the Public, a conversation with Dr. Claudia Benitez-Nelson

Dr. Claudia Benitez-Nelson, professor in the Department of Earth Ocean and the Environment, University of South Carolina, presented Nutrient Cycling, Storm water runoff, and Communicating Science to the Public on Tuesday, March 1, 2022 via Zoom as part of SUNY ESF’s Women in Scientific and Environmental Professions Spring Seminar Series. This seminar was sponsored by ESF Women’s Caucus.

Dr. Claudia Benitez Nelson. Click for video.

Dr. Benitez-Nelson research focuses on the biogeochemical cycling of phosphorus and carbon, largely in marine environments, and how these elements are influenced by natural and anthropogenic processes. During the seminar she discussed her most recent research on inland and coastal nutrient cycling in relation to planning for stormwater surges.

Benitez-Nelson's team sought to establish the rate of sediment accumulation in stormwater ponds, determine the role these ponds play in the regional cycling of carbon and nutrients, and to identify the sources of organic matter to pond sediments in different growing urban areas in the Waccamaw watershed. “This was for us a real opportunity to truly connect more closely with the communities that we were working in” said Benitez-Nelson when explaining how their findings would benefit the homeowners close to the ponds. Her findings suggest that Particulate Organic Matter (POM) is a better proxy for liability than Dissolved Organic Matter (DOM) and may control Biological Organic Matter (BOD) loads. Her lab continues research on different topics related to aquatic organic matter.

Benitez-Nelson is often asked how she “starts to have these conversations about not just pollution, urbanization, sustainability, but talking about climate and how climate change is influencing where people are living their lives.” She shared that she is part of Science Moms, a non-partisan group of climate scientists, who also happen to be mothers, that “really talk about climate, the need collective action” as well as mitigation efforts, particularly in conversation with other mothers, for the benefit of all their children. 

Dr. Benitez-Nelson received B.S. in chemistry and oceanography from the University of Washington and a Ph.D. in oceanography from the Woods Hole Oceanographic Institute/Massachusetts Institute of Technology Joint Program. She has an extensive publication record which includes lead authored pieces in both Science and Nature. Dr. Benitez-Nelson also serves as Associate Dean, for Instruction, Community Engagement and Research.

Record attendance for 2019 Take our Daughters and Sons to Work Day

In lieu of school on April 25, ESF employees and students brought 44 8–11 yr olds from 30 area schools to try their hands at a variety of ESF-fostered careers during the college's 26th annual Take our Kids to Work Day program (AKA Kids' Day).

Over the course of the day, kids built terrariums with Linda McGuigan, Allison Oakes and Hannah Pilkey, who work on the Chestnut Project.  They explored a few chemical reactions on paper prior to activating self-inflating balloons with Chemistry’s Kate Bailie.  They developed storyboards with Sarah Grabman of the new Digital Storytelling Studio.    
Teams, each given the same materials and coached by a member of either Engineering for a Sustainable Society or Engineers without Borders, competed to most effectively remove particulates through Water Filtration (staff support provided by Karen Karker, Instructional Support Specialist, Environmental Resources Engineering).  Following a quick lesson on bird anatomy and habit, EFB graduate students Laine McCall and Ravyn Neville took advantage of the beautiful afternoon and lead a Bird Walk across campus and into Oakwood Cemetary.  Because life is more than work, we also featured an art session!  Kids upcycled materials that Maura Stefl, Office of Experiential Learning and Outreach, waylaid from the wastestreams from campus (curtains and cardboard), homes (fence posts), and a small business (mitten scraps) into a succulent plantscape.  Cool lessons:  art flowers don’t need to look like any that exist in real life!  Take inspiration from the colors and textures of the materials, and add dimension. (Thank you: Mark Poupore for cutting fenceposts to size; Lauren Gibbs, Laura Crandall, Julie Fishman, Brad Fierke, for their help with glue guns.) The day concluded with Heather Engelman, Forest and Natural Resource Management and We All Need Trees, a rapid examination of a number of household products and foods that make use of tree products for strength, flavor, and texture, and some ties to ESF’s programs of study.

After the formal program, kids reunited with their adults and headed to a few Earth Week programs, including perennial favorites Birds of Prey and Tie Dye.

We also thank:  

  • Group Guides Brad Fierke, Julie Fishman, Laura Crandall, Amy McGuigan, Malika Carter, Jackie Whitehead, Lenny Leonard, and Linda McGuigan, with the assistance of Philippe Vidon, Erin Tochelli, Katherina Searing and Sarah Houck.

Where Science and Policy Meet: the Career of an EPA Scientist



In Adventures at the Science-Policy Interface, Dr. Brooke Hemming, Sr. Physical Scientist, United States Environmental Protection Agency (EPA), gave the “lecture I wished I’d heard as a graduate student.” Dr. Hemming discussed the role scientists play in public policy, developed through her exemplary work with the interdisciplinary team charged with establishing the scientific foundation for “criteria” air pollutant limits via synthesis of data with emergent understanding of atmospheric science and the acute and long-term impacts of exposure to human health and ecosystems. But she also used the Thursday, March 28, 2019 Women in Scientific and Environmental Professions lecture to outline different science career paths and preparatory opportunities. 
Dr. Hemming first discussed four main career areas for a professional in the sciences: 1) academic research, 2) non-profit research, assessment, and advocacy, 3) government research and/or assessment, and 4) government policy analysis and/or development. On the subject of her career area (government research and/or assessment), she acknowledged that her projects and deadlines are pre-determined for her, and that her work is subject to considerable public scrutiny because she is a public servant.

Dr. Hemming offered the advice that when choosing a career path, ask yourself three things:
1)     What are your talents and skills?
2)     What do you want to be doing on most days of your week?
3)     Own who you are, what you have to offer, and what you need to be happy before you start making major career decisions.
Dr. Hemming advised those interested in environmental policy is to learn the issues of most concern to science advocates, and to take advantage of education-oriented opportunities to work directly with policymakers. 

Dr. Hemming went on to talk about an organization she has previously worked, the American Association for the Advancement of Science (AAAS), and her time as an Environmental Science and Policy Fellow at the organization. Over the course of her time at the AAAS, she visited countries like Mexico and Russia to meet with members of government and local scientists to discuss the state of the climate in those countries.

The next part of Dr. Hemming’s lecture was on the role of the EPA in policy formulation, which includes: 1) responding to Congress and 2) assessing & reporting on the state of the science relevant to environmental policy. She described the role of Congress as having the power to confirm the EPA leadership, set budgets for the EPA, and create new offices within the agency. She gave an example of a report to Congress she had worked on, regarding assessment of black carbon particulate matter.

The National Center for Environmental Assessment (NCEA) is the division of the EPA that primarily handles assessment of the science relevant to environmental policy. As a member of the NCEA staff, Dr. Hemming works to provide the interface between 3 groups employed in the fields of policy and science: 1) researchers in other parts of the EPA’s Office of Research and Development, 2) the larger scientific community who generate new findings and data that inform policy, and 3) the regulators in the EPA’s regional offices (e.g. the Office of Air and Radiation) who use that data to make decisions to protect public health and the environment. She went on to describe the Clean Air Act of 1970, which called for upper limits on ambient concentrations of 6 criteria air pollutants (ozone, nitrogen oxides, sulfur oxides, particulate matter, carbon monoxide, and lead), and its influence on her work. Dr. Hemming’s office publishes its work as Integrated Science Assessments (ISAs) that summarize the most policy-relevant science, particularly regarding assessment of risk to human health, and the ISAs are made available to the public online.

Dr. Hemming concluded her lecture by providing a list of important skills that she believes are not usually developed in graduate school, but that are essential for entering the workforce:
1)     humility (being willing to learn from your co-workers)
2)     collaborative problem-solving (as collaboration is required for all “fully-effective solutions”)
3)     self-awareness (knowing your own shortcomings, and how they affect your interactions with co-workers and shareholders)
4)     listening to your shareholders and partners (“listen dynamically”, be engaged, sympathetic)
5)     work-life balancing (realizing that although graduate school doesn’t encourage a balanced life, you need to find a way to set aside time to take care of yourself)

Since 2002, Dr. Brooke Hemming has worked in Air Quality assessment at the Research Triangle Park campus of the US EPA. Her training began at a community college, continued at UC Berkeley and work at the Lawrence Berkeley National Laboratory. Her doctoral research at Stanford University was conducted at the NASA-Ames Research Center and the Molecular Physics Laboratory at SRI International. Her post-doc in atmospheric aerosol thermodynamics was completed at the CA Institute of Technology, and was followed by a fellowship at AAAS.  Since joining the EPA, she has received multiple awards for her work on NAAQS reviews, and a gold medal for her leadership and co-authorship of the assessments that formed the basis of the Carbon Dioxide Endangerment finding that CO2 is a harmful pollutant. She is the editor of a new book series, Climate and Policy, under the Anthem Press Environmental and Sustainability Initiative, and has served for several years as a technical advisor on the Department of Defense Strategic Environmental Research Program Resource Conservation and Resiliency Technical Committee, and as an advisor on the North Carolina State Climate Change and Society Program Advisory Board. She has also served as a science advisor to Paperhand Puppet Intervention.

Dr. Hemming’s lecture was co-sponsored by ESF’s Department of Chemistry and the ESF Women’s Caucus.

Antibiotic Resistance as an Environmental Contaminant


As part of the requirements of FOR /496797, Perspectives on Career and Gender, student share responsibility for reporting on the WiSE Professions Speaker Series.  The following was prepared by Stacy Furgal, a MS student in EFB.

              Dr. Amy Pruden, of Virginia Tech, presented her research relating to antibiotic resistance and opportunistic pathogens as environmental contaminants on Tuesday, April 26.  This lecture was part of SUNY ESF’s Women in Science and Environmental Professions Spring Seminar Series.

              The lecture focused on the problem of antibiotic resistant genes (ARGs) and opportunistic pathogens (OPs) found in our water (both municipal and well), and the potential problems this could cause from a public health perspective. The water infrastructure in our country is antiquated and aging, and poorly suited to address these new contaminant issues. Current regulatory monitoring requirements do not apply to ARGs and OPs, but rather were designed with ingestion exposure type pathogens, like Cholera, in mind. Now the primary sources of water associated outbreaks are like Legionnaires’ Disease, which is acquired via breathing in particles that contain the bacteria, not ingesting infected water.

With that in mind, her multidisciplinary team is working to blend engineering and biology to find solutions to this complex issue. Dr. Pruden explained, using some of her and her colleagues’ work in Flint, MI, an examples. As most people know, a crisis occurred in Flint when the source for city drinking water was switched from Lake Michigan to the Flint River. The water from the Flint River had a higher salinity content, which corroded the pipes and caused lead to leach out into the water. Less well known is that this also released iron that acted as fuel for Legionella bacteria to grow. Her team investigated the increased number of reported cases of Legionnaires’ Disease and was able to link it to the corroded pipes through genetic markers.

Her team was also involved in a project that compared the amount of ARGs and OPs in regular potable water versus water that had been treated and reused, or  “recycled.” The study found that recycled water had more microbial activity, and more abundance and diversity of ARGs. It was also clear that the water tested at the water treatment facility had a different “resistome” (collection of ARGs) than water coming out of a tap in a home receiving water from that facility.

Both of Dr. Pruden’s studies highlighted that there should be a shared responsibility between utilities (water treatment facilities) and homeowners. Water quality at the point of use, i.e. in homes, is of the greatest concern to public health. Using a holistic approach, we need new frameworks and updated mitigation strategies to handle the new and emerging issue of antibiotic resistant genes and opportunistic pathogens. This is best done by a multidisciplinary team, like Dr. Pruden’s, that brings biologists, engineers, chemists, utility managers, and more, together to tackle the problem.

Dr. Pruden received her B.S. in Biology and Ph.D. in Environmental Science from University of Cincinnati. She is a professor in the Department of Civil and Environmental Engineering and the Associate Dean and Director of Interdisciplinary Graduate Education in the Graduate School at Virginia Tech, as well as a W. Thomas Rice Professor. She serves as the Director of Strategic Planning for the Institute for Critical Technology and Applied Sciences Water Sustainability Thrust, is an Associate Editor for the journal Biodegradation, and serves on an advisory panel on Contaminants of Emerging Concern (CECs) in recycled water. Dr. Pruden has published more than 50 peer-reviewed manuscripts and book chapters on subjects pertaining to bioremediation, pathogens, and antibiotic resistance.

Henry speaks: Mercury in the Onondaga Lake Remedy?

As part of the requirements of FOR496/797 Environmental Career Strategies for Women, students share responsibility for reporting on the presentations in the Women in Scientific and Environmental Professions Speaker Series.  The following was prepared by Liz Canal, Rebecca Maurer, and Shavaun Jenkins.

Dr. Betsy Henry, Senior Managing Scientist, Exponent, Schenectady, launched SUNY ESF’s 2009 Women in Scientific and Environmental Professions Speaker Series with  Mercury in the Onondaga Lake Remedy on February 24. The Department of Chemistry and the ESF Women’s Caucus jointly sponsored the seminar.
Dr. Henry discussed the background of mercury contamination including the global mercury cycle over the last 20 years, US fish consumption advisories, analysis of mercury in water, and the mercury transformation processes in aquatic systems.  Attention was then focused on the history of mercury bioaccumulation in Onondaga Lake and the remedial investigation that took place from 1992-2001, as well Exponent’s involvement with that process.  
Dr. Henry is working with Honeywell International (formerly AlliedSignal) and the DEC to clean up Allied’s mass depositing of mercury over the years. Mercury had been used as an electrode in the production of chlorine, caustic potash (KOH) and caustic soda (NaOH); briny groundwater made Syracuse uniquely suited for these industries.  Elemental mercury is of particular concern because of its potential to methylate in non-oxygen environments such as deep water and sediment.  Methylmercury is a soluable neurotoxin that bioaccumulates, becoming more concentrated as larger fish eat smaller ones. 
Henry explained that Honeywell, DEC & EPA had been working toward “a phase of a consent decree” on how the lake could be cleaned.  The data took over a decade to collect and assisted in creating a feasibility study, where all the alternatives to cleaning the lake were evaluated. January 2007 marked the beginning of the five year design schedule that would allow the cleaning of the sediment from the lake to actually begin.
The first step in remediation was to decrease external sources of mercury contamination from former Allied Signal, particularly the former LCP Bridge Street Plant, Metropolitan Syracuse Wastewater Treatment Plant (METRO), and groundwater infiltration in 2007.  Soil washing has separated more than 7 tons of elemental mercury from 85 tons of processed soil.  To stop groundwater infiltration, a barrier wall was set up from 35 to 70 feet in depth.  The groundwater that would have entered Onondaga Lake is now pumped to a treatment plant.  The next step in the Remedy will be elimination of mercury through dredging and capping.   “Natural recovery” will be monitored for the two-thirds of the lake bottom where clean lake sediment is burying the contaminated waste sediment.  Additions of oxygen and nitrate are planned to delay the production of additional methylmercury, and Onondaga County is spending $500 million to stop polluting the lake with sewage by 2012. These steps are designed to meet the remedial goal of reducing mercury concentration in sediment, water, and fish tissue to levels that are “protective of human health and environment.”   
In 2012 they will “get inside the lake to address internal processes” including resuspension of in-lake waste deposits, which are primarily made up of calcium carbonate (CaCO3); methane gas ebullition, poor water diffusion, and methyl mercury production.
Dr. Henry’s experience includes management of investigations, risk assessment, and agency negotiations at some of the most prominent mercury sites in the country. With a broad background in the transport and fate of contaminants in the environment, Dr. Henry specialty is in the transport, fate, and bioaccumulation of mercury in both terrestrial and aquatic systems. More recently, she has worked closely with engineers during remedial design to understand and address risks associated with mercury contamination.
Dr. Henry received her B.S. in agronomy from Colorado State University and her Ph.D. in Environmental Engineering from Harvard University.  In addition to her position with Exponent, she serves as president of ReTree Schenectady, a non-profit organization dedicated to the planting, care, and conservation of current and future generations of trees in the City of Schenectady.

Chemical Remediation of Contaminants in Water and Soil using Fenton Advanced Oxidation Systems

As part of the requirements for FOR 496/797 Environmental Career Strategies for Women, students share the responsiblity for reporting on the speakers in the Women in Environmental Professions Speaker Series.  The following was prepared by Shavaun Jenkins and Christina Quinn.
 
Dr. Ann Lemley, a Professor in the College of Human Ecology at Cornell University, concluded SUNY ESF’s 2009 Women in Scientific and Environmental Professions Speaker Series with a talk entitled Chemical Remediation of Contaminants in Water and Soil using Fenton Advanced Oxidation Systems on April 7. The Department of Chemistry and the ESF Women’s Caucus co-sponsored the seminar.
Dr. Lemley discussed her current research concerning the use of chemical means for the degradation of contaminants in water and soil. Contaminated soils pose potentially serious threats to surface and ground water quality, particularly when contaminant concentrations are high due to accidental spills or discharges. Therefore, the goal of her work is to develop a practical system for the removal or treatment of contaminants, including pesticides, pharmaceuticals, and other organics, from water and soil systems.
Beginning with a brief introduction into the background of pesticide contamination and the complications associated with its remediation, Dr. Lemley described how advanced oxidation processes (AOPs) offer fast and effective techniques for remediation. Specifically, her lab focuses on the application of Fenton reactions (Fe2+ + H2O2 àFe3+ + OH- + *OH) to degrade contaminants in water and soil/clay slurries through an indirect electrochemical method, known as Anodic Fenton treatment (AFT), that generates Fe2+ via electrolysis. This treatment offers several advantages including the avoidance of problems with hygroscopic salts, reducing the need for reactions at extreme pH’s, and the ability to control the release of reagents and measure the *OH radical reaction rates.
            Within Dr. Lemley’s research group, an AFT kinetic model has been developed and, using competitive kinetics, optimized to allow for the measure of concentrations of coexisting contaminants. Furthermore, this model has been revised to accommodate nitrogen-containing pesticides (tricosenes).  Dr. Lemley concluded her presentation with an illustration of the application of the AFT kinetic model in soil slurries and layered clays. Through the use of X-ray diffraction, the adsorption of several probe chemicals, including mecoprop (anionic), carbaryl (neutral) and paraquat (cationic) was measured along with their subsequent degradation rate by AFT. While anionic and neutral chemicals can be effectively and completely degraded by AFT, the removal of cationic chemicals in soil/clay may prove more difficult due to strong electrochemical interactions. Future research will be focused on developing electrochemical systems for different applied situations and the study of a variety of other contaminants, including animals antibiotics, and their rate of degradation and subsequent degradation products.
Dr. Lemley received her B.A. in Chemistry and Education from St. John’s University, and both her Master’s and Ph.D. in Chemistry from Cornell University.  Currently, Dr. Lemley is a Professor and Chair of the Department of Fiber Science & Apparel Design, working in the Field of Environmental Toxicology, at Cornell University. She is also on the Editorial Board of several journals (including the Bulletin of Environmental Contamination and Toxicology, Journal of Agricultural and Food Chemistry, and Journal of Environmental Science and Health, Part A) and active with the NYSTAR Center for Environmental Quality centered at Syracuse University.

Heine Discusses Green Chemistry and Cradle to Cradle Product Design

By Amanda Meyer and Judy Crawford

Dr. Lauren Heine, Director of Applied Science for the GreenBlue Institute, gave a presentation entitled Green Chemistry and Cradle to Cradle Product Design on Tuesday, February 6, 2007 as part of SUNY-ESF's Women in Scientific and Environmental Professions Spring Seminar Series. The Faculties of Chemistry and Paper and Bioprocess Engineering and the ESF Women's Caucus jointly sponsored the event.

Dr. Heine's lecture focused on material health and green chemistry's contribution to it. Material health refers to products that are safe to both humans and the environment during their full life cycle, with a focus on design for safe, productive return to nature or industry. Material health is important because materials can directly and indirectly affect the health of entire ecosystems, as well as humans. After defining material health and its importance, Dr. Heine cited examples of both direct and indirect impacts of bad product design. Dr. Heine then turned her attention to strategies.

The four strategies for material health described by Dr. Heine were Know Your Product (Inventory), Know the Potential Impacts (Impact Assessment), Choose Green Chemical Products and Processes, and Remember the Big Picture. “Knowing your product” means identifying all components and ingredients of the product, ideally down to 100 ppm. This strategy includes requiring full ingredient disclosures and creating lists of suppliers who are either preferred (P-list) or should be avoided (X-list) based on their product components.

“Knowing the Potential Impacts” means preventing harmful consequences by understanding the toxicity, hazard, and risks associated with your materials over their full life cycle. Toxicity refers to the adverse effects of exposure to various agents to living organisms and ecosystems. When assessing toxicity, it is important to keep the dose and the timing of the exposure in mind. Hazards include such things as extreme toxicity to humans and ecosystems, bioaccumulation, and more. Risk equals hazard multiplied by exposure.

 “Choosing Green Chemical Products and Processes” includes selecting safer and healthier alternatives; designing healthy alternatives in collaboration with suppliers; and looking for emerging green chemistries and technologies. Green chemistry is the design of chemical processes and products to reduce and/or eliminate hazardous substances. Dr. Heine outlined twelve principles of green chemistry and provided examples of products and companies using green chemistry.

Dr. Lauren Heine received her doctorate in Civil and Environmental Engineering from Duke University. She is currently the Director of Applied Science at the non-profit institute GreenBlue. Dr. Heine is also directing the development of CleanGredientsTM and the Sustainable Textile Metrics standard. In addition, she consults and publishes on issues relating to green chemistry, alternatives assessment and sustainable material flows.

The next lecture in this series, Global warming:  the science behind the headlines, is scheduled for Tuesday, March 6, and will feature Dr. Brenda Ekwurzel, Climate Scientist, Global Environment Program, Union of Concerned Scientists, Washington, DC.  This visit will also be part of Syracuse University’s Women in Science and Engineering Speaker Series.  For more information, please visit http://www.esf.edu/womenscaucus

Dr. Caryl Fish Speaks on Abandoned Mine Drainage


As part of the course requirements for FOR 797-2, students share the responsibility for reporting on the speakers in the Women in Scientific and Environmental Professions Speaker Series.  The following press release was prepared by Yvonne Paul and April Baptiste. 

Dr. Caryl Fish, Professor of Environmental Chemistry at Saint Vincent College, discussed Abandoned Mine Drainage: A Resource for Undergraduate Education at ESF on February 22, 2005 as part of SUNY ESF’s Women in Scientific and Environmental Professions Speaker Series.

Dr. Fish’s presentation focused on the clean-up of abandoned mine drainage sites in Pennsylvania. During the 1800s and early 1900s, there were a number of coal mines in operation in Pennsylvania.  During active mining, water would be pumped from the mines to facilitate the process.  After the mines were depleted, pumping would cease and the excavated areas would fill with water. Groundwater chemically reacts with the mineral pyrite (iron sulphide – FeS2) that is commonly found along the seams of coal.  The iron and sulphur in the pyrite dissolve in the water to create iron hydroxide and sulphuric acid. As the iron and sulphur-rich groundwater reaches the surface through drill holes and other openings, the iron in the water reacts with air and essentially “rusts.” When the water drains into nearby rivers and streams, these water bodies are “stained” orange as iron-rich compounds oxidize and settle.  This drainage can be quite acidic, unless there is sufficient calcium carbonate in the groundwater to neutralize it.  The iron-rich compounds and other chemicals in the water decreased the flora and fauna that would naturally inhabit these waters. 

The Monastery Run Project near Saint Vincent College began in 1993 to test passive treatment for mine drainage.  Three multi-celled wetland ponds or cells were created to reduce the iron that was prevalent in the local streams.  Water moves from one cell to the next, reducing the concentration of iron dramatically between cells.  The first cell is aerated via the movement of falling water to maximize precipitation of iron compounds. The last cells contain cattails, which act as physical filters, trapping free iron molecules.  The wetlands in this project area can retain 250 pounds of iron oxide per day.  Less than 1% of the iron that entered the wetlands leaves.  This passive method is now a common means to improve water quality from AMD.  In addition, the wetlands are used to enhance science learning for chemistry and non-chemistry students, assist teacher education for grades K-9, provide general wetland education for the public, and serve as the basis for teacher education and senior research projects.

Dr. Fish is a Professor of Chemistry at Saint Vincent College in Latrobe, PA.  She is also the director of St. Vincent's Summer Institute in Watershed Restoration and its Environmental Education Center.   Dr. Fish earned her B.S. from Manchester College, MBA at the University of Dayton, and PhD from SUNY-ESF. 

This presentation was jointly sponsored by SUNY College of Environmental Science and Forestry, its Faculty of Chemistry, Women's Caucus, Alumni Association, and Graduate Student Association.  For information about upcoming speakers, please visit http://www.esf.edu/womenscaucus

Bendz Speaks About Environmentally Friendly Computers


As part of the course requirements of FOR 496/797 Women in Scientific and Environmental Professions, students share the responsibility of reporting on our speakers for distribution to co-sponsors and the Knothole.  The following press release was prepared by by Nicole Kadey and Susan Tumwebaze.

Diana Bendz returned to her alma mater (ESF Chemistry ’68) to discuss the growing concern and importance of “Environmentally Friendly Computers: New Concepts of Design, (Re) Use and Recycle.”  Ms. Bendz is a Senior Location Executive for the IBM Corporation in Endicott, New York. 

Ms. Bendz’s discussion focused on the digital revolution and its environmental considerations, industry response, and challenges ahead.  The digital revolution included many applications of communication, knowledge access and E-business and E-commerce, distance learning, intelligent buildings, intelligent transportation and entertainment of demand.

Environmental considerations concern the disposal of an overabundance of process waste, the use of excessive energy in recycling, and the tremendous use of PC products and materials by consumers.  Consumers are scrapping computers more than recycling them. The U.S. has not implemented any federal regulations on CRT landfill restrictions as the individual U.S. states still control regulation.  The industry’s response has been primarily concerned with computer design issues, and secondarily with recycling issues. There is an increased awareness in the designing computers for the environment (DfE) and a change in how they are recycled.

There are many challenges ahead for the industry.   There must be a continuance in DfE initiatives that include upgrade-ability, maintenance and repair, material selection, use of recycled material, and design for disassembly and recycling.   Costs must be lowered by creating logistical networks that reduce transportation and processing costs -- an increasing percentage and value of recovered parts -- and by improving the collaboration and harmonization of take back programs initiated by the federal government.  There must be an increased investment in technology with more demand for recycled materials, an improved computer materials separation process, the ability to identify parts for interchangeability and reuse, an industry standard classification for used or certified parts, and an increased ability to reuse packaging material.  There needs to be an improvement in the economy of recycling computers and their parts, and a more effective public/private partnerships which may be coordinated by federal programs, federal R&D initiatives, and responsible policy initiatives. 

Ms. Bendz has been with IBM for 34 years, beginning as a process engineer during the early days of semi-conductor production. Through the years, she filled diverse roles throughout the company until named an executive in 1991. In this position, she developed IBM's much-duplicated program for the design, manufacture, and disposition of environmentally conscious products.

This presentation was jointly sponsored by the ESF Faculty of Chemistry, the Graduate Student Association and the ESF Women’s Caucus.  Only one speaker remains in the 2004 Women in Scientific and Environmental Professions Speaker Series.  GM’s Christine Sloane will address “Sustainable Transportation:  Hydrogen and Fuel-Cell Cars” on April 6.  For more information about the series, visit:  http://www.esf.edu/womenscaucus.

Press Release: Swackhamer and Estrogen Mimics


As part of the course requirements for FOR 797 Women in Scientific and Environmental Professions, students share the responsibility for reporting on our speakers for distribution to co-sponsors and the Knothole.  The following press release was prepared by Karen Howard.

Dr. Deborah L. Swackhamer, Professor of Environmental Chemistry in the School of Public Health at the University of Minnesota, presented her research on Estrogen Mimics and Sex Education for Fishes on Tuesday, January 27, 2004 as part of SUNY ESF’s Women in Scientific and Environmental Professions Spring Seminar Series.  The Faculties of Chemistry and Environmental and Forest Biology, the Graduate Student Association, and the ESF Women’s Caucus jointly sponsored the seminar. 
            Dr. Swackhamer discussed a variety of endocrine disrupting compounds in the environment (also called EDCs) that mimic endogenous hormones.  Examples include synthetic hormones, organohalogens, pesticides, detergent components, and plasticizers.  These compounds bind to estrogen receptors in organisms.  The effects of these compounds on organisms and the levels of exposure required to cause effects are still widely unknown. 
Attention was first focused on EDCs through observations of their effects in the field.  Colonial nesting birds around the Great Lakes have been greatly affected by DDT (through eggshell thinning) as well as PCBs and dioxins, which cause developmental deformities resulting in early death.  Nearly 50% of the beluga whales in the St. Lawrence River exhibit hermaphroditic characteristics thought to be caused by organochlorine exposure.  These and similar cases led Congress in 1998 to enact regulations requiring the screening of all commercially available chemicals for endocrine disrupting ability.  This screening has been delayed to date by the lack of validated assays.
            Within Dr. Swackhamer’s research group, studies have been conducted to determine the effects of EDCs on walleye and carp.  They have found that wild fish captured during the spawning season in the discharge channel from a sewage treatment plant exhibit high levels of estradiol, low testosterone levels, smaller gonads than reference fish, and a lack of milt.  However, a controlled laboratory study exposing fish directly to the effluent from the treatment plant produced no reduction in sperm quantity or quality but did indicate a behavioral failure to compete for females during spawning.  Current and future research is focused on the identification of an appropriate indicator compound that could be used in the field to identify populations affected by EDCs.
Dr. Swackhamer received her B.A. in Chemistry from Grinnell College, and her M.S. in Water Chemistry and Ph.D. in Oceanography and Limnology from the University of Wisconsin at Madison.  She serves as co-director of the Water Resources Center at the University of Minnesota.  She sits on the Science Advisory Board of the International Joint Commission of the U.S. and Canada, and serves on the Advisory Board for the National Undersea Research Program of NOAA for the North Atlantic-Great Lakes Region.

Finding Evidence of Life in the Solar System


by Maryann Ashworth and Amanda O’Connor

Why would we want to build an instrument that can detect traces of life on other planets? An “in situ” instrument has numerous advantages. The most important being that we know we can analyze a sample that is brought back from outer space.  This extremely cautious procedure presents many problems.  The most important being whether or not the sample will actually be in good condition to analyze. There have been two major crashes of Mars explorations in the last five years leading to the belief that “in situ” would pose no difficulty.  We are guaranteed that the sample can at least be analyzed by stabilizing its condition from the first impact. Since it is more feasible to analyze the sample “in situ,” Dr. Fogel began to think about how to build such an instrument.
Obviously, the first step in building an instrument that can determine if there is life on another planet begins right here on Earth. Earth environments such as hydrothermal springs and vents are homes for Archae. It has been hypothesized that the creation of Archae and Eubacteria were most likely how life started on Earth.  This is also a clue as to how life could have been started or is started on other planets.  Scientists can also use current-day landscapes to scientifically work backwards. Dr Fogel discussed taking a modern environment and analyzing the relationships within that environment that have survived geologic time to indicate the time period when there were first signs of life.
Scientific data such as chemical clues that exist as biochemical remains and inorganic remains were discussed. Biochemical remains range from large molecules (living cells) to isotopic patterns formed by living organisms.  One important fact was that organic remains are present as biominerals (calcium carbonate, for example) or gases such as oxygen and methane that are produced in quantity solely by living organisms.
The next question that was posed was if biosignatures survive the geologic record. If they do not, then what does and how would we recognize it? Dr. Fogel performed a number of experiments observing the rate of carbon and nitrogen decay and concluded that bacterial signatures overprinted plant signatures. Fortunately, the microbial record will survive.
