Health risks by fish consumption were assessed following the investigation of the residual levels of 25 pesticides in four kinds of freshwater fish from 4 aquatic product markets in Beijing using ultrasonic extraction-GC-MS. Eighteen pesticides were detected from the 48 samples collected. Acetochlor (97.9%) and beta-HCH (93.8%) showed high detection rates. The pesticide detected in highest concentration was chlorothalonil (1 779.4 microg x kg(-1)), followed by deltamethrin (620.3 microg x kg(-1)). Coexistence of 2-10 kinds of pesticides in fish was found with the total pesticide concentration in range of 2.7-1932 microg x kg(-1). Based on the averaged fish consumption of Beijing residents, the health risk of the studied pesticides by freshwater fish consumption was calculated as 0.043 43, suggesting a relatively low health risk.
通过超声波萃取-气相色谱-质谱联用技术，对北京4个水产品市场的4种淡水鱼中25种农药的残留水平进行调查后，评估了食用鱼类带来的健康风险。在所采集的48个样本中检测出18种农药。乙草胺（97.9%）和β-六六六（93.8%）的检出率较高。检出浓度最高的农药是百菌清（1779.4微克×千克-1），其次是溴氰菊酯（620.3微克×千克-1）。在鱼类中发现存在2至10种农药共存的情况，农药总浓度范围为2.7至1932微克×千克-1。根据北京居民的平均鱼类消费量，计算出食用淡水鱼摄入所研究农药的健康风险为0.04343，表明健康风险相对较低。
