【摘要】：根据水质目标管理需求,在太湖流域选定包含饮用水源地、入湖河口、目标污染水体和参照水体在内的共计10个采样点位,调查其药物和个人护理用品(pharmaceuticals and personal care products,PPCPs)分布特征,并对定量筛出的PPCPs进行毒性数据的收集和整理,初步分析太湖流域PPCPs的生态风险,提出优先管理PPCPs污染物名录.结果显示,太湖水体中定性检出PPCPs类化合物33种,其中17种在定量检出限以上,浓度范围为0.03~25.77ng/L;咖啡因、西地那非、布洛芬、避蚊胺等4种PPCPs在太湖流域具有较高或者潜在的生态风险,从不同的点位来看,入湖河口的2个点位PPCPs风险较高,检出的种类相对较多,需重点关注.
[Abstract]:According to the demand of water quality target management, 10 sampling sites including drinking water source, estuary, target polluted water and reference water were selected in Taihu Lake basin. To investigate the distribution characteristics of and personal care products (PPCPs) of pharmaceutical and personal care products. The toxicity data of PPCPs was collected and sorted out, the ecological risk of PPCPs in Taihu Lake basin was analyzed, and the list of pollutants of PPCPs was put forward. 33 species of PPCPs compounds were identified qualitatively in Taihu Lake, 17 of which were above the quantitative detection limit, and the concentration range was 0.03 ~ 25.77 ng / L; Caffeine, sildenafil, ibuprofen and desalamines have high or potential ecological risks in Taihu Lake basin, which can be seen at different sites. The risk of PPCPs at the two sites in the estuary of the lake is relatively high, and the species detected are relatively large, which should be paid more attention to.

【正文快照】： 药物和个人护理用品(pharmaceuticals andpersonal care products,PPCPs)作为环境中新型污染物的重要组成部分,具有较强的生物活性,尽管环境残留水平较低,但长期暴露依然会给人类健康和生态环境带来潜在风险.据报道,在地表水中检出的各种PPCPs化合物中,具有雌激素效应的物质占
