Pharmaceuticals, Fertilizers, Pesticides and Antimicrobial Products Blamed for Transgender Fish

Male Fish Now Exhibiting Female Traits Due to

Toxic Chemicals and Pharma Runoff


More than 80 percent of male bass in the Potomac River on the U.S. Atlantic coast are producing eggs or showing other female traits, the nonprofit Potomac Conservancy has warned, in a call for more research into the causes of intersex fish.

In a recent U.S. Geological Survey (USGS) report, intersex fish were found in a third of all 111 sites tested across the United States, including in major waterways such as the Mississippi River and the Rio Grande. The phenomenon occurred in 16 different species, but was most common in male smallmouth and largemouth bass.

Researchers agree that the phenomenon is almost certainly caused by the presence of
pollutants in the water, including endocrine- (hormone) disrupting chemicals and the residue of pharmaceutical products.

"We have not been able to identify one particular chemical or one particular source," said USGS biologist Vicki Blazer. "We are still trying to get a handle on what chemicals are important."

Among the chemicals likely to be contributing to the problem, Blazer cited birth control pills and other hormone-containing
drugs, antibacterial products including tissues, personal care products (especially those containing fragrances), flame retardants, pesticides and fertilizers.
