Article Synopsis
- Exposure to environmental estrogens in wastewater treatment effluents leads to feminization in male fish, including egg development in testes.
- A study on roach fish showed that offspring from mothers exposed to wastewater did not have increased susceptibility to feminization or reproductive issues compared to those from clean water.
- Male roach with a mild intersex condition were still able to reproduce successfully, suggesting that exposure to WwTW effluent may not significantly affect reproductive capabilities.
Background: Treated effluents from wastewater treatment works can comprise a large proportion of the flow of rivers in the developed world. Exposure to these effluents, or the steroidal estrogens they contain, feminizes wild male fish and can reduce their reproductive fitness. Long-term experimental exposures have resulted in skewed sex ratios, reproductive failures in breeding colonies, and population collapse.
