The EPA toxicity assessment of GenX PFAS chemicals is a positive step on the roadmap and TRI concerns


WASHINGTON – The Environmental Protection Agency (EPA) today published its human health toxicity assessment for GenX chemicals, a subset of per- and polyfluoroalkyl substances (PFAS).

The EPA’s assessment is a critical review of the known effects of GenX chemicals on human health and includes the level of exposure that the EPA believes will not cause harm. GenX is used to replace other hazardous PFAS chemicals and has been found in the environment at worrying levels, particularly in communities near industrial sites.

The following is statement of Anna Reade, employee at NRDC (Defense Council for Natural Resources):

“After incorporating key scientific advice into the GenX assessment, it has improved significantly over previous drafts and is becoming an important guide in setting the standards needed to protect people at risk from these chemicals across the country. GenX is being marketed as a “safe substitute” for PFOA, but the fact that the EPA indicates that GenX poses health concerns ten times lower than PFOA makes it clear that these claims are unsupported by science. “
