Hormone-mimickers widespread in Great Lakes

and this is "not a good thing" (TM)

This isn’t the first time researchers have found the compounds in the Great Lakes. In 2007 Environment Canada reported that the compounds were in sediment of a Great Lakes coastal wetland in Ontario and were accumulating in the tissue of local invertebrates.

Another Canadian study from 2009 tested 28 sites in lakes Erie, Huron and Ontario, and found alkylphenols distributed widely in sediments in the lower Great Lakes, with concentrations higher in sediments near larger cities.
