Comparing Risk Science Choices Underpinning Formaldehyde Exposure Levels Established by Independent Regulatory and Advisory Bodies 

Many occupational exposure limits exist for formaldehyde. In 2024, the U.S. Environmental Protection Agency issued two documents recommending health-protective exposure levels: a final formaldehyde Integrated Risk Information System (IRIS) assessment and a draft formaldehyde Toxic Substances Control Act (TSCA) Risk Evaluation. In its review of the draft TSCA Risk Evaluation, the TSCA advisory board, the Science Advisory Committee on Chemicals (SACC), recommended a comparison of the conclusions reached in the draft TSCA Risk Evaluation with the decisions made by other global regulatory authorities along with a coherent technical explanation of the differences.
