EPA: Taking Action on Toxics and Chemical Safety

For all of their beneficial uses, chemicals can also pose potential risks: manufacturing them can create emissions and waste, and exposure to them can impact our health and the environment. One of EPA’s highest priorities is making sure our children, our homes, and our communities are safer from toxic chemicals.

Last October, Administrator McCarthy asked EPA employees to log into GreenSpark, our internal online employee engagement platform, and share stories of the innovative and collaborative work that they are leading to take action on toxics and chemical safety. I’d like to share some of their exciting work with you.


Developing Innovative Science: EPA’s Office of Research and Development, with support from the Office of Chemical Safety and Pollution Prevention, is working to change the way we evaluate chemical safety to make it quicker and easier to understand the potential toxic effects of chemicals on human health and the environment. Here are a couple of great examples:

We’ve developed the Toxicity Forecaster (ToxCast), which uses automated chemical screening technologies to understand the effects of chemical exposure. ToxCast evaluated more than 2,000 chemicals from a broad range of sources, including potentially “green” chemicals that could be safer alternatives to existing chemicals. Based on this work, the new Interactive Chemical Safety for Sustainability (iCSS) Dashboard provides a user-friendly web-based application that offers product manufacturers, researchers, and others a faster way to evaluate the safety of chemicals. ToxCast data is also being applied in the Endocrine Disruptor Screening Program to target priority chemicals and avoid expensive and time-consuming animal testing methods.

CHEMzebraAnother innovative approach that our Office of Research and Development scientists are developing is a program using zebrafish to rapidly screen standard chemicals and their green alternatives for their ability to affect developing embryos.

CHEMHorizMaking Use of Data: Several EPA programs work daily to make sure the public, communities, regulators and industry have access to data that keeps people safe. EPA’s Office of Environmental Information is working to integrate facilities data relating to chemical plants and their relationship to communities. This work, in collaboration with the Department of Homeland Security, Department of Labor, and other agencies supports Executive Order (EO) 13650: Improving Chemical Facility Safety and Security and helps inform planning and emergency preparedness and response for safer communities.

Providing Technical Assistance: Artisanal and small scale gold mining is the largest man-made source of mercury. Mercury exposure at high levels can harm the brain, heart, kidneys, lungs, and immune system. To reduce airborne mercury emissions from artisanal and small scale gold mining, EPA’s Office of International and Tribal Affairs worked with Argonne National Laboratory to develop a simple mercury capture system (MCS).

Data collected during site visits in the Amazon and high Andes areas of Peru showed that in shops with the installed MCS technology, mercury vapor concentrations were reduced by 80% compared to shops without the technology. We are now working to raise awareness of the mercury capture technology in developing countries through partnerships with key organizations.

CHEMpeoplestandingWorking in Collaborative Partnerships: Working with local partners including the New York State Department of Environmental Conservation (NYSDEC), EPA Region 2 is helping improve chemical management in high school and college laboratories and the adoption of green chemistry practices through hands-on training for high school science teachers and college faculty in New York. More than 200 teachers from 138 school districts and 29 college and university faculty have participated in trainings, and faculty participants have produced ten case studies on implementing green chemistry practices in college and university settings. This is just one example of the work that our Office of Chemical Safety and Pollution Prevention is leading along with our Regional Offices to promote innovations in green chemistry.

Please join me in thanking all of the talented, dedicated employees who have contributed to these and other amazing activities that improve the human health and environment of the communities we serve.
