摘　　要：针对YZ河流重点江段水体中药物及个人护理品(PPCPs)的污染特征,开展了分布规律、来源解析及生态风险评价研究。通过多点位采样及气相色谱-质谱联用技术,分析了PPCPs的空间分布与季节性变化特征。结果显示,PPCPs浓度在下游区域及春秋季显著升高,主要污染源为生活污水和农业排放。生态风险评价表明,下游部分采样点存在较高生态风险。研究提出了基于污染来源和区域分布特征的治理建议,为中小型河流水体污染控制提供了科学依据。A study was conducted on the pollution characteristics of drugs and personal care products(PPCPs)in key river sections of YZ River,including distribution patterns,source analysis,and ecological risk assessment.The spatial distribution and seasonal variation characteristics of PPCPs were analyzed using multi-point sampling and gas chromatography-mass spectrometry techniques.The results showed that the concentration of PPCPs significantly increased in downstream areas and during spring and autumn seasons,with the main sources of pollution being domestic sewage and agricultural emissions.The ecological risk assessment indicates that there are high ecological risks at downstream sampling points.The study proposes governance recommendations based on pollution sources and regional distribution characteristics,providing a scientific basis for controlling water pollution in small and medium-sized rivers.
