Fluoride Action Network

National Research Council (2006)

An overview of the NRC's groundbreaking report on fluoride toxicity, including excerpts of its key findings and recommendations, statements from the panelists, and a discussion of its relevance to water fluoridation and sulfuryl fluoride.

Relevance to Fluoride Pesticides

The NRC report is not only relevant to current drinking water standards for fluoride, it is also highly relevant to EPA’s regulation of fluoride-based pesticides. Prior to the release of the NRC report, the EPA granted a request from Dow AgroSciences to use sulfuryl fluoride as a fumigant on food and food-processing facilities. The EPA based its approval of Dow’s request on a reference dose (8 mg/day, or 0.114 mg/kg/day) that was derived from the very standard that the NRC found to be hazardous to health. Following the publication of NRC’s report, therefore, the Fluoride Action Network (FAN), joined by the Environmental Working Group (EWG) and Beyond Pesticides (BP), petitioned EPA to stop the use of sulfuryl fluoride.

In response to FAN’s challenge (which included detailed submissions spanning an nine-year stretch from 2001 to 2010), the EPA’s Office of Pesticides Program agreed in January 2011 to withdraw its approval of sulfuryl fluoride tolerances (permissible residue levels) on food. Following EPA’s announcement of its intention to phase out sulfuryl fluoride, Dow AgroSciences and numerous food processing facilities filed voluminous objections. As a result of this pressure, EPA is now re-considering its decision.
