How does perchlorate affect human health?
Credible studies show perchlorate’s direct effects on human health are limited to the thyroid. High levels of perchlorate can prevent the thyroid gland from absorbing iodide (which it needs to make hormones) from the bloodstream. This in itself is not dangerous however, because the body automatically compensates for this. Further, according to the U.S. Food and Drug Administration, Perchlorate-induced changes to thyroid function have not been demonstrated in studies of humans exposed to perchlorate.
