The results suggest that this thyroid-disrupting chemical may be more widespread than previously believed. The report was published Feb. 22 on the Web site of Environmental Science & Technology, a peer-reviewed journal of the American Chemical Society, the world's largest scientific society. Perchlorate occurs naturally and is also a primary ingredient in solid rocket fuel. The chemical, which has been showing up in many segments of the environment, can interfere with iodide uptake in the thyroid gland, disrupting adult metabolism and childhood development. The researchers, led by Professor Purnendu Dasgupta, Ph.D., of the university's department of chemistry and biochemistry, analyzed 47 dairy milk samples purchased randomly from grocery stores in 11 states, and 36 breast milk samples from women recruited at random in 18 states. Every sample of breast milk contained perchlorate, and only one sample of dairy milk contained no detectable levels... "
