摘　　要：采用高效液相色谱-质谱联用法,对亚运会期间珠江广州段水中五氯苯酚(PCP)的质量浓度进行分析研究.结果显示:在亚运会期间,不同采样点位PCP的检出率为100%.PCP质量浓度为3.0～6.0 ng.L-1,采样点位的PCP质量浓度分布呈现中游>下游>上游规律.通过与亚运会前珠江PCP质量浓度和周边自来水、污水处理厂出水中PCP质量浓度的对比,发现亚运期间珠江水和自来水中PCP质量浓度均低于亚运会前,污水处理厂出水在一定程度上影响珠江水中PCP的质量浓度.Concentrations and distribution of pentachlorophenol （PCP） in the water of Guangzhou section of Pearl River during the Asian Games were determined by liquid chromatography-mass spectrometry. The results showed that the detection rate of PCP at different sampling points was 100% during the Asian Games. The concentrations were in the range of 3.0 - 6.0 ng · L^-1, and in the sequence of middlestream 〉 downstream 〉 upstream. Our results indicate that PCP in tap water and the Pearl River water during the Asian Game are lower than those before the Asian Games. Moreover, the water from sewage treatment plants may affect the concentrations of PCP in the water of Pearl River.
