A 1997 report said that 1 to 3% of women of reproductive age in the United States ate so much fish that they placed their fetuses in a dangerous state of exposure to mercury, according to the new release of Clarkson University

'Determining the level of accumulation of hazardous substances, such as mercury or PCBs in freshwater fish living in lakes, is essential for public health organizations (health workers) to bring private the most appropriate and safe consumption of fish, 'said Thomas Holsen, professor of environmental and public engineering at Potsdam, NY University.

Holsen said the project will analyze about 110 samples annually. In addition, scientists will conduct various testing methods to identify current harmful substances not measured in fish. 'Our discovery will provide evidence that the scientific community can . more accurately assess the dangers of the harmful substances found in the health of fish populations and animals. consume them " - he said.

With the participation of scientists and engineers from Clarkson State University (New York) in New York, Fredonia, and SUNNY, Oswego.
