USA: EPA releases chemical screening data on 1,800 chemicals

The U.S. Environmental Protection Agency (EPA) announced the release of chemical screening data accessible through the new in­teractive Chemical Safety for Sustainability or iCSS Dashboard. The iCSS Dashboard provides access to data from innovative screening technologies for chemicals that are found in industrial and consumer products, food additives, and drugs.


As part of this data release, EPA is announcing the ToxCast Data Challenges, a series of challenges inviting the science and technology community to work with the data and provide solu­tions for how the new chemical screening data can be used to predict potential health effects. Challenge winners will receive awards for their innovative research ideas.


The data were gathered through advanced techniques, includ­ing robotics and high-throughput screening, as part of an on­going federal collaboration to improve chemical screening. The collaboration, Toxicity Testing in the 21st Century (Tox21), is comprised of EPA, the National Institutes of Environmental Health Sciences/National Toxicology Program, National Center for Advancing Translational Sciences, and the Food and Drug Administration.


Only a fraction of chemicals in use in the United States have been adequately assessed for potential risk. This information is useful for prioritizing chemicals for potential risk as well as pre­dicting if chemical exposures could lead to adverse health effects.
