What was the result of the National Academy of Sciences (NAS) January 2005 report?
A. The NAS report, “Health Implications of Perchlorate Ingestion,” concludes that a dose of 0.007 mg/kg/day would cause no observable effects in the most sensitive individuals. NAS is careful to note that this “reference dose” is not a drinking water standard and that additional work is needed in order to set a drinking water standard. The NAS believes that perchlorate’s impact on the thyroid’s ability to process iodide is temporary and can be mitigated by internal adjustments within the body.
