716 R. Golden Declaration of interest The author is employed at ToxLogic LLC, a consulting firm that provides advice to private and government clients on toxicological issues pertaining to human health, and was compensated by the Formaldehyde Council Inc. (FCI) and the American Chemistry Council (ACC) for the preparation of this review. In addition, on behalf of FCI and ACC, the author has provided comments to various governmental agencies, including US EPA, NTP, NCI, and ATSDR as well as to the National Academy of Sciences panel that reviewed the US EPA/IRIS assessment on formaldehyde-related issues. Many of the written and oral comments served as the basis for the present review. The interpretation of the data presented, as well as the conclusions reached, is the sole responsibility of the author. The author alone is responsible for the content and writing of the paper.
