Study on the Nonpoint Sources of Perchlorate in the environment.
10-09 Widespread occurrence of perchlorate has been reported in recent years in surface water bodies, ground water aquifers, and agricultural products across the U.S. This perchlorate, which may have both anthropogenic and natural sources, can be problematic because the highly soluble perchlorate anion is relatively inert and difficult to remove by conventional water treatment methods. Because several toxicological studies indicate that trace amounts of perchlorate can cause thyroid cancer and child developmental problems, there is increasing interest in characterizing acceptable contamination levels as well as the ultimate sources of perchlorate in the environment. The stable isotope ratios of Cl and O can potentially be used to distinguish the source(s) of perchlorate in a given location and to evaluate the extent of biodegradation. Several papers related to this topic are included here.

Perchlorate exposure was not significantly correlated with breast milk iodine concentrations. Perchlorate was detectable in infant formula, but at lower levels than in breast milk. 47% of women sampled may have been providing breast milk with insufficient iodine to meet infants requirements.
