A panel of top US scientists has
backed a US Environmental Protection Agency draft
toxicological risk assessment review that found
formaldehyde, a chemical with broad industrial uses,
to be a human carcinogen. However, the
Aug. 9 report, by the US National Academy of
Sciences (NAS), was challenged
by the American Chemistry Council (ACC), a trade
association, even before it was publicly released.
The NAS review was commissioned by
the EPA to assess the draft risk assessment, which
was completed more than a year ago and was conducted
through the agency’s Integrated Risk Information
System (IRIS) program. The
EPA’s assessment cites evidence that inhaling
formaldehyde causes nasopharyngeal cancer, sinonasal
cancer, and myeloid leukemia in humans. If
finalized, the IRIS assessment will serve as a
benchmark for future formaldehyde-related
regulations.
