Endocrine disrupting compounds (EDCs), represented by steroid hormones, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and bisphenol A have been determined in four sediment cores from the Gulf of Mexico, New Orleans surface water (Lake Pontchartrain Mississippi River), influent effluent a municipal sewage treatment plant. During five-month monitoring selected EDCs River (MR) Lake (LP) 2008, 21 29 OCPs MR 17 LP were detected; was detected all samples. Steroid hormones (estrone, 17β-estradiol 17α-ethinylestradiol) occasionally. Total EDC (OCPs + PCBs A) concentrations two samples found to vary 148 1112 ng L−1. Strong correlation distribution total OCPs, between solid phases LP, while moderate or no existed MR. PCBs, ocean sediments, measured range 77 1796 g−1 dry weight. The also untreated treated with removal efficiency 83% for but 17α-ethinylestradiol.
