| 摘 要： | 用固相萃取和气相色谱法对西江（珠江的主干）进行了为期1a的水相和颗粒相中17种有机氯农药（OCPs）测定。结果表明，水相OCPs的含量范围在2．28～10．21ng／L之间，颗粒物是OCPs的含量变化在20．29-58．74ng／g之间，经过分析得出西江水体中，有机氯农药主要以水相为主，颗粒物中农药所占比例远小于水相中。就OCPs来讲，研究区水质符合国家I类水标准。其来源方面地表径流对此有很大的贡献。西江中六六六类、DDT类和总OCPs的年通量为272．3，164．6，1245．3kg。

| Abstract: | Concentration and temporal distribution of OCPs in both water and suspend particulate matter （SPM） were measured fi-om June, 2005 to June, 2006 in the West River. The West River is the major tributary of the Pearl River, South China. Concentration of OCPs in water samples and in SPM ranged from 2.28 to 10.24ng/L and 20.29 to 58.74ng/g, respectively. The estimated annual loadings of HCHs, DDTs and total OCPs were 272.3, 164.6, 1245.3kg. |
