On April 14, 2022, the Environmental Protection Agency (EPA) released draft conclusions in a report updating its analysis regarding formaldehyde exposure, suggesting that long-term exposures to small amounts of formaldehyde in the environment can increase the risk of rare head and neck tumors, leukemia, and other threats to health. The conclusions are not final agency action. Still, manufacturers should be aware of the potential for EPA’s analysis to influence both regulation and litigation at both the state and federal levels.
For over a decade, there has been much debate and study on the long-term effects of exposure to formaldehyde. The EPA’s new analysis is an update of a 2010 draft EPA report that was heavily panned by scientists, legislators, and chemical manufacturers and that drove the EPA back to the drawing board. For example, the National Academies of Sciences, Engineering, and Medicine criticized the 2010 draft EPA report for failing to describe the rationale behind its methodology and failing to sufficiently support its conclusions.
