Article Synopsis
- The study analyzed endocrine disrupting chemicals (EDCs) in 11 Minnesota lakes with varying land uses and no wastewater discharges, focusing on water, sediment, and POCIS for chemical indicators.
- EDCs like bisphenol A and 17β-estradiol were found in 90% of the lakes at low concentrations, along with signs of endocrine disruption in resident fish and caged fathead minnows.
- The research highlights that the presence of EDCs and their effects in fish are widespread and influenced by multiple, unpredictable sources beyond just wastewater, not strictly tied to land use or lake productivity.
Ten different perfluoroalkyl acids (PFAAs), including perfluooctane sulfonate (PFOS), were measured in 30 common carp (Cyprinus carpio) fillets collected from three sites on the Upper Mississippi River in Minnesota in an effort to evaluate the potential impact of PFAA emissions in this area. Samples upstream of the city of St. Cloud (reference site) had median PFOS concentrations of 8.
