用固相萃取和气相色谱-质谱法对珠三角某条河流进行了多环芳烃的测定。结果表明水相中多环芳烃的浓度范围介于30.96～357.90 ng/L之间,平均为150.14ng/L。以2环（Nap）和3环（Ace,Acy,Flu,Phe,Ant）为主。说明低分子量的多环芳烃在水相中居于优势地位。颗粒相中多环芳烃的浓度范围介于292.54 ng/g和873.65 ng/g之间,平均为574.32 ng/g。以3环和4环（Fluo,Pyr,BaA,and Chry）为主,高分子量五、六环的多环芳烃比例远远高于水相中的比例。lgKoc与lgKow在本研究区具有良好的相关性（R2=0.554）。

This paper is a survey on the concentration and temporal distribution of OCPs and SPMs （suspend particulate matter） of a river in the Pearl River Delta. The concentration of PAHs in the water samples ranged from 30.96 ng/L to 357.90 ng/L with a mean value of 150.14 ng/L. And the total concentration of SPM varied between 292.54 ng/g and 873.65 ng/g （mean 574.32 ng/g）. A good correlation existed between its lgKoe and lgKow.
