Flame retardant levels in Virginia fish are among the highest found

Article Abstract:

Fish found from the Roanake and Dan rivers in Southern Virginia contain the highest level of polybrominated diphenyl ethers (PBDEs) which are commonly found in flame retardants.

PCBs may mar results of in utero mercury testing

Article Abstract:

Children born to mothers who consumed large amounts of fish during pregnancy may have neuro-developmental disabilities due to large amounts of mercury in the fish, but others say high levels of polychlorinated biphenyls may be clouding those results.

British study finds endocrine disruption widespread in native fish

Article Abstract:

Researchers at Brunel University in Uxbridge, UK has released the first definitive study on the sexually disruptive effects of sewage water contamination on wild fish populations. The three-year study involved the study of the effects of effluents on sewage treatment plants on the population of the native fish called roach, which showed wide-spread sex reversal especially in male populations. The sex reversal was found to be due to the natural and synthetic hormones which are components of sewage effluents that act as potent endocrine disrupters, capable of effecting physiological changes in male roaches, such as the presence of egg cells in the testes or the transformation of the sperm duct into something akin to an ovarian cavity. The researchers are extrapolating the study, hoping to see the potential effects of endocrine disrupters in larger bodies of water.
