The U.S. Geological Survey (USGS) in Lansing, Michigan, will reportedly update a 2010 study which showed that the amount of cosmetic and pharmaceutical chemicals doubled downstream from an Adrian wastewater treatment plant when compared to an upstream sample. Musk fragrances from beauty products such as lotion and perfume were apparently measured at 200 to 500 nanograms per liter. USGS scientists are now measuring the total load of chemicals from several rivers as they discharge into the Great Lakes, and the new testing site is Monroe. According to a news source, the U.S. Fish and Wildlife Service plans to issue a study later this summer analyzing fish and bird eggs found along the Detroit River to determine whether similar contaminants are present. A Service toxicologist said research is ongoing elsewhere in the United States to study the potential effect of certain chemicals on fish populations. See Monroe News, June 24, 2014.
