Heiko Schoenfuss, director of St. Cloud State University's Aquatics Toxicology Lab, who received national media attention for his study of pollutants in the Mississippi River, is now garnering attention for turning that focus on lakes. In the summer of 2008, Schoenfuss joined the state Pollution Control Agency and the U.S. Geological Survey to study endocrine disruptors in 11 Minnesota lakes. Researchers found endocrine-disrupting chemicals to be widespread in low concentrations in the lakes. The researchers collected water and sediment samples from each lake and analyzed them for 110 chemicals in pharmaceuticals, hormones, pesticides and personal care products. The list of pollutants detected was similar to those found in rivers, including detergents, caffeine and hormones.
