摘要
通过分析我国地表水中药物和个人护理品(PPCPs)主要污染源排放特征,识别和筛选出咖啡因、卡马西平和磺胺嘧啶为我国地表水环境中的指示性PPCPs(i-PPCPs),分别指征城镇生活污水、城镇污水处理厂出水和养殖废水三类特征污染排放源.同时,基于筛选的i-PPCPs开展了初步应用研究,结果表明,生活污水是北运河和黄浦江流域地表水中PPCPs的主要来源.研究结果为构建更综合和有效的PPCPs的溯源体系,识别我国城市地表水环境中PPCPs的主要排放源提供了理论依据.
In the present study, caffeine, carbamazepine and sulfadiazine were identified as indicator PPCPs (i-PPCPs) in the surface water environment of China, which indicated the typical emission sources of domestic wastewater, effluent of municipal wastewater treatment plants and livestock wastewater, respectively. Then, the identified i-PPCPs were used for a preliminary source apportionment of PPCPs in the urban water environments. The results indicated that domestic wastewater was the main source of PPCPs in the surface water of Beiyun River in Beijing and Huangpu River in Shanghai. The findings provide a theoretical basis for building a more comprehensive and effective source apportionment system of PPCPs and identifying the main sources of PPCPs in urban surface water environment in China.
