Genetically Altered Fish Found in Polluted Minnesota Lakes
Minnesota's lakes annually attract millions of visitors, including many who come to cast lines in the fish-abundant waters.

November 02, 2010 /24-7PressRelease/ -- Minnesota's lakes annually attract millions of visitors, including many who come to cast lines in the fish-abundant waters.

But a new study says that as clear as those lakes may seem to be they contain an alarming amount of chemical compounds from detergents, plastics and pharmaceuticals.

The chemicals are so prevalent, the study says, that about 10 percent of male fish have been genetically altered and show female sexual characteristics.

The Minnesota Pollution Control Agency and St. Cloud State University conducted the research with the support of the U.S. Geological Survey. The purpose was to check possible pollution of the waters tested and the long-term effects of pollution on the fish population.

The compounds discovered do not disintegrate over time. They were found even in the most remote lakes of northern Minnesota.
