Pharmaceuticals and personal care products (PPCPs) are recognized as a group of emerging contaminants closely related to anthropogenic activities, which capture increasing attention worldwide. To evaluate the anthropogenic disturbances on PPCP distribution and sources, this study investigated the distribution and sources of 50 PPCPs along the 2300 km long Jinsha River and revealed different anthropogenic disturbances on PPCPs. Results showed that 40 out of the 50 PPCPs were ubiquitously detected among these river water samples, with the concentrations varied from less than 1 ng/L to more than 500 ng/L. Although most PPCPs concentrations were much lower in the Jinsha River than in highly developed rivers, the prevalence of PPCPs suggested the widespread use and improper disposal of PPCPs in the Jinsha River. The risk assessment also revealed that some PPCPs posed risks to aquatic organisms in the Jinsha River. Anthropogenic activities including human habitation and dam construction had different influence on PPCPs. PPCP distribution varied significantly across the “Hu Huanyong line”, indicating human habitation significantly influenced PPCP distribution. Dam construction was insignificant in altering PPCP distribution throughout the Jinsha River. Moreover, the land use index indicated degradation level of multiple lands related to anthropogenic activities and represented the major sources of PPCPs in the Jinsha River. Most PPCPs were correlated with anthropogenic lands, for example, antibiotics, analgesics, and endocrine disrupting chemicals mainly originated from artificial surfaces, whereas other PPCPs mainly originated from cultivated lands. Together, this study indicates the disturbances of multiple anthropogenic activities on PPCP distribution and sources along the Jinsha River, which contributes to PPCP management in rural areas.

人为干扰金沙江流域各地药品和个人护理产品的分布和来源

药品和个人护理产品(PPCP)被认为是与人为活动密切相关的一组新兴污染物,在全球范围内引起越来越多的关注。为了评估人为干扰对PPCP的分布和来源的影响,本研究调查了2300公里长的金沙江沿岸50个PPCP的分布和来源,揭示了PPCP的不同人为干扰。结果表明,在这些河水样品中,共检测出50种PPCP中的40种,浓度范围从小于1 ng / L到大于500 ng / L。尽管金沙江中大多数PPCP的浓度都比高度发达的河流要低得多,但PPCP的流行表明金沙江中PPCP的广泛使用和不当处置。风险评估还显示,一些PPCP对金沙江的水生生物构成了风险。人为活动(包括人类居住和水坝建设)对PPCP的影响不同。PPCP的分布在“胡焕庸线”之间变化很大,这表明人类的居住环境对PPCP的分布有很大影响。大坝建设对改变金沙江沿岸的PPCP分布影响不大。此外,土地利用指数表明了与人为活动有关的多片土地的退化程度,并代表了金沙江PPPPs的主要来源。大多数PPCP与人为土地相关,例如,抗生素,止痛药和破坏内分泌的化学物质主要来自人工表面,而其他PPCP主要来自耕地。
