Federally-Sponsored Formaldehyde Study Finds No Link to Leukemia
The National Toxicology Program (NTP) has released a report from a recently completed National Institute of Environmental Health Sciences (NIEHS) study, which found that formaldehyde inhalation did not cause leukemia in strains of mice genetically predisposed to these types of cancers. The mice were exposed to maximum tolerated doses of formaldehyde (15 ppm), more than 100 times the occupational exposure limit, and did not develop nasal tumors or demonstrate any increased prevalence of leukemia or any other type of cancer.
These findings add to a growing body of evidence that formaldehyde inhalation does not cause leukemia, as supported by a recently published, peer-reviewed article in the well-known journal Regulatory, Toxicology and Pharmacology. The article, entitled Six years after the NRC Review of EPA’s Draft IRIS Toxicological Review of Formaldehyde Regulatory implications of new science in evaluating formaldehyde leukemogenicity, chronicles a litany of recent scientific studies that consistently do not support a link between formaldehyde and leukemia. Based on all of this new evidence, the study authors assert that a conclusion of causation is not justified and that EPA must take into account this body of new science as it revises its 2010 draft formaldehyde IRIS risk assessment.
