Environmental Risk Associated with Antibiotics and Pharmaceuticals inSurface Waters

摘要

The fate and transport of 26 common human and veterinary antibiotics, four antiinflammatories(ibuprofen, diclofenac, ketoprofen, and naproxen), the antiepileptic drugcarbamazepine, and a widely-used X-ray contrast agent, iohexol, in a small, urban watershed thatis impacted by wastewater discharges from three communities that include major hospitals,several large residential nursing homes, and several research centers. The watershed ultimatelylinks an impacted reservoir to a downstream drinking water source, and the levels of thesepollutants in the aqueous phase have been evaluated in order to begin a comprehensiveecological risk assessment associated with residual pharmaceutically active compounds insurface waters.
