摘要: Abstract Passive sampling is highly complimentary to spot in environmental analysis. A polar organic chemical integrative sampler (POCIS) was extensively tested optimize its performance under both controlled and field conditions. The passive subsequently used for the analysis of estrone, 17β-estradiol, 17α-ethynylestradiol, bisphenol A, propranolol, sulfamethoxazole, meberverine, thioridazine, carbamazepine, tamoxifen, indomethacine, diclofenac meclofenamic acid sewage effluent river water. Under laboratory conditions, kinetics compound uptake by POCIS were linear during 10-day exposure. rates target compounds significantly greater using polyethersulfone instead polysulfone membrane, enhanced with increasing sorbent exposure area. Together water sampling, optimized deployed River Ouse, West Sussex, UK obtain field-derived which, endocrine disrupting chemicals (EDCs), higher than those from experiments. Both demonstrated that most frequently detected waters, daily changes pollutant concentrations pharmaceuticals EDCs. aqueous all elevated at a outfall, which confirmed be an important source river. validated then successfully estimate water, good agreement pharmaceuticals.
