This is the first study, near here that show's the pollutants are in fact in public drinking waters. Many of the other studies are in ocean fish, polar bears and in wilderness areas. Plenty of studies have been done to id the pollutants, the EPA does nothing while whining how hard of a job it is to do.
Abnormally developed fish, possessing both male and female characteristics, have been discovered in the Potomac River in the District and in tributaries across the region, federal scientists say -- raising alarms that the river is tainted by pollution that drives hormone systems haywire.
The results were striking, according to Vicki S. Blazer, a fish pathologist with the U.S. Geological Survey. More than 80 percent of all the male smallmouth bass they found were growing eggs, including all of the fish caught at four of the seven survey sites. The intersex condition doesn't change the fish's outward appearance but can be detected under a microscope.
At the site in Washington, seven of 13 male largemouth bass showed some kind of unusual feminine characteristic. Six of the seven fish tested positive for a protein used to produce eggs, and three of the seven contained eggs, Blazer said.
Taken together, Blazer said, the results on both bass species seemed to indicate that the Potomac watershed has a problem with "endocrine disruptors," contaminants that interfere with nature's chemical signaling. In this case, she said, the contaminants might have turned on bodily processes that normally are only active in female fish.
