Journal ArticleDOI
Reproductive disruption in fish downstream from an estrogenic wastewater effluent.
TL;DR: The results indicate that the reproductive potential of native fishes may be compromised in wastewater-dominated streams.
Journal ArticleDOI
Combined Sewer Overflows: An Environmental Source of Hormones and Wastewater Micropollutants
TL;DR: Assessment of the relative contribution of CSO bypass flows and treated wastewater effluent to the load of steroid hormones and other wastewater micropollutants from a WWTP to a lake finds that concentrations of hormones and many WMPs in samples from treated discharges can increase with increasing flow due to decreasing removal efficiency.
Journal ArticleDOI
Quantification of steroid hormones with pheromonal properties in municipal wastewater effluent
TL;DR: The measured concentrations of steroids often exceeded olfactory detection thresholds at which fish detect these steroids, and in several cases, the steroid concentrations were comparable to levels at which pheromonal responses have been observed in fish.
Journal ArticleDOI
Demasculinization of male fish by wastewater treatment plant effluent.
Alan M. Vajda,Larry B. Barber,James L. Gray,Elena M. Lopez,Ashley M. Bolden,Heiko L. Schoenfuss,David O. Norris +6 more
TL;DR: The hypothesis that the reproductive disruption observed in this watershed is due to endocrine-active chemicals in the WWTP effluent is supported.
Journal ArticleDOI
Contaminants of emerging concern in fresh leachate from landfills in the conterminous United States
Jason R. Masoner,Dana W. Kolpin,Edward T. Furlong,Isabelle M. Cozzarelli,James L. Gray,Eric A. Schwab +5 more
TL;DR: Leachate from landfills in areas receiving greater amounts of precipitation had greater frequencies of CEC detections and concentrations in leachate than landfILLs receiving less precipitation.
