摘　　要：为确定珠江三角洲水体悬浮颗粒物中多环芳烃和有机氯农药的含量和来源,对珠江上游的两条重要支流西江、北江水体中的悬浮颗粒物分期进行了两次采样分析,测定了水体中悬浮颗粒物的含量,分析了其中多环芳烃、有机氯农药的含量。其中,北江水体中悬浮颗粒物中的PAHs的总量分别为928.8、1259.7ng·g-1干质量,西江水体中悬浮颗粒物的PAHs总量分别为660.1、1130.7ng·g-1干质量,其来源主要为石化燃料的燃烧与排放。北江水体悬浮颗粒物中的有机氯农药总量为41.9、135.3ng·g-1干质量,西江为78.54、108.7ng·g-1干质量,由沿岸农田排放入水体。并发现,西江北江沿岸的农田,仍旧在使用DDT、硫丹等农药。To determine the content and source of PAHs and OCPs in the suspended particles, we took a sampling for the suspended particles from the West River and the North River, two important rivers of Pearl River water system, upriver from the Pearl River, determined the content of the suspended particles in the river, and analyzed the content of the PAHs and the OCPs in them. We knew that gross of the PAHs in particles from the North River was 928.8 ng·g^-1 and 1 259.7 ng·g^-1 while the West River was 660.1 ng·g^-1 and 11 30.7 ng·g^-1, they were derived from petroleum and combustion. The gross of the OCPs in particles from the North River was 41.9 ng·g^-1 and 135.3 ng·g^-1, while the West River was 78.5 and 108.7 ng·g^-1. They were input from the farms along the river side. We also found out that the coastwise farmlands of the two rivers were still put in the organochlorine pesticides, such as DDT, endusulfan.
