通过对北京地区药品和个人护理用品（PPCPs）未经处理的废水和经污水处理厂处理的废水的直接排放，估算了其环境负荷。15种PPCP成分的年环境负荷从16.3 kg（心得安）到9.85吨（咖啡因）不等。建立了基于环境负荷估算的PPCP污染逸度模型。模拟结果与北京地区PPCP的观测值接近。未经处理的废水对北京PPCP污染的贡献很大，从46%（心得安）到99%（咖啡因）不等。目标ppcp的总环境负担从0.90 kg（心得安）到536 kg（咖啡因）不等。水是影响ppcp命运的最重要媒介。基于蒙特卡罗的ppcp浓度分布与观测结果一致。降低PPCP污染最重要的途径是提高废水收集率和采用深度处理技术。
The environmental loads of pharmaceutical and personal care products (PPCPs) in Beijing were estimated from direct discharge of untreated wastewater and WWTP treated effluent. The annual environmental loads of 15 PPCP components ranged from 16.3 kg (propranolol) to 9.85 tons (caffeine). A fugacity model was developed to successfully estimate the PPCP pollution based on the estimated environmental load. The modeled results approximated the observed PPCP concentrations in Beijing. The untreated wastewater contributed significantly to PPCP pollution in Beijing, ranging from 46% (propranolol) to 99% (caffeine). The total environmental burden of target PPCPs ranged from 0.90 kg (propranolol) to 536 kg (caffeine). Water is the most important media for the fate of PPCPs. Monte Carlo-based concentration distributions of PPCPs are consistent with the observed results. The most important way to reduce the PPCP pollution is to both improve wastewater collection rate and adopt deep treatment technologies.
