摘要: Pharmaceutical fate in surface water depends on a combination of physical and chemical processes, but currently, little information is available cumulative dissipation rates effluent-dominated receiving waters. In this study, were calculated for pharmaceutical compounds two streams municipal wastewater effluents using results from passive samplers. Seventeen pharmaceuticals detected at the sampling locations, first-order found to range between 0.03 −0.02 h⁻¹, indicating that some conserved, while others rapidly dissipated over several kilometers downstream source.
