摘　　要：利用气相色谱-电子俘获检测(GC-ECD)方法对南四湖表层沉积物中13种有机氯农药进行了分析测定。每个采样点均检出了有机氯农药,与世界其它类似水体比较,南四湖表层沉积物中的有机氯农药处于低水平含量,属于低生态风险水平。多数点位有机氯农药均是由于历史上使用造成的,但不排除个别点位存在新的污染源。To find the concentration level of organochlorine pesticides（OCPs） in surface dediments of Lake Nansihu, 13 kinds of OCPs were detected by GC-ECD method. OCPs has been detected at all of sites. Compared other similar places, the level of OCPs in surface sediments of Lake Nansihu was at lower status and belonged to low-level ecological risk. Most of OCPs contributed to historic using. However, new contamination source were found in two sites.
