Perchlorate Levels

JAMA. 2010;304(18):2005. doi:10.1001/jama.2010.1609

As the Environmental Protection Agency decides whether to establish a regulatory standard for perchlorate in drinking water, the Government Accountability Office (GAO) has issued a report that may help in the decision-making process.

Perchlorate is a man-made and naturally occurring chemical that can disrupt the uptake of iodide in the thyroid, potentially interfering with thyroid function and hindering fetal and infant brain development and growth. Man-made perchlorate is used in rocket fuel, explosives, fireworks, and other products.
