摘要
以上海市某大型畜禽养殖场为研究区域,揭示了该养殖场雨水径流中19种药物和个人护理品(PPCPs)的存在水平和时间变化规律,阐明了雨水径流的初期冲刷效应.结果表明,不同采样时间点雨水径流样品中目标PPCPs浓度范围为0.62~166ng/L,15种PPCPs检出率可达100%;目标PPCPs在降雨前期(径流产生的15~30min)出现浓度峰值,随后浓度降低并趋于稳定;通过描述径流污染输出负荷同径流量关系的LP-F曲线和前30%径流流量排放的污染物负荷比指标(FF30)进一步证明该养殖场雨水径流中PPCPs具有显著的初期冲刷效应;研究结果为有效控制畜禽养殖场雨水径流中PPCPs污染提供了重要参考.
The occurrence,temporal variation and first flush effect of 19PPCPs in stormwater runoff in a typical swine farm in Shanghai were investigated.The results show that the concentrations of target PPCPs were in the range of 0.62~166ng/L and 15 out of 19PPCPs exhibited a detection frequency of 100%.The concentrations of target PPCPs peaked in the initial 15~30 minute once the stormwater runoff occurred,then decreased continuously.By using LP-F curve and FF30 which describe the relationship between the pollution load and runoff volume,a significant first flush effect was verified in the stormwater runoff in the swine farm.These findings will provide an important reference for effectively controlling PPCPs pollution in stormwater runoff in livestock farms.
