EPA Chemicals of Concern is a list compiled by the United States Environmental Protection Agency (EPA) containing chemical substances found to be harmful or toxic to human health and the environment. This list was published in accordance with a 2016 amendment to the Toxic Substances Control Act (TSCA), which requires that the EPA evaluate and address the potential risks of chemical substances. Exposure to any of the 90 chemicals on the list has been found to present a risk to health or the environment during processes of manufacturing, processing, distribution, usage, or disposal.1 Listed substances include formaldehyde, mercury, lead, asbestos, glyphosate, hazardous air pollutants, per- and polyfluoroalkyl substances (PFAS), pesticide chemicals, and polychlorinated biphenyls (PCBs). The EPA includes a profile of each chemical with information and resources geared towards professionals and people at risk of coming in contact with it. The website also describes the EPA’s procedure for reviewing new and existing chemicals.2
