摘要: 为了研究贵州百花湖水体中有机氯农药(OCPs)对人体的潜在健康风险,在百花湖及其周边布设8个采样点分别采集水样,采用液液萃取-毛细管气相色谱法对OCPs的残留状况进行测定。结果显示,水样中11种有机氯的总含量范围为15.5~43.8 ng•L-1,其中,BHCs和DDTs含量范围分别为3.2~14.6和1.2~7.8 ng•L-1。采用美国国家环境保护局(EPA)推荐的健康风险评价方法的评价结果表明,百花湖水体中OCPs的致癌风险和非致癌风险均低于国际辐射防护委员会(ICRP)推荐的最大可接受风险水平,表明百花湖水体中11种OCPs对人体健康风险处于较低水平。

Abstract: In order to investigate potential health risk of residue of organochlorine pesticides (OCPs) in the water of Lake Baihuahu to human beings, water samples were collected from 8 sampling sites located in Lake Baihuahu.Concentrations of OCPs in the water were determined with gas chromatography. Results show that the total concentration of the 11 kinds of organochlorine pesticides found in the water samples varied in the range of 15.5-43.8 ng•L-1, of which 3.2-14.6 and 1.2-7.8 ng•L-1 was BHCs and DDTs, respectively.Based on the model of water environmental health risk assessment recommended by USEPA, the health risk assessment indicates that the carcinogenic and non-carcinogenic risks of OCPs residue in the water of the Lake are both lower than the highest acceptable level of risk set by ICRP.

Key words: Lake Baihuahu, organochlorine pesticides, gas chromatography, health risk assessment
