摘　　要：为了更好的了解哈素海水体中PAHs的污染程度,本文对水体中PAHs的污染特征进行分析,并解析其主要来源,利用风险熵值法和健康风险评价模型进行生态风险评价。水体中检出9种PAHs,浓度为269.79~1340.69 ng·L^(-1),主要来源为石油泄漏混有燃料燃烧排放。湖中33.33%单体化合物属于严重污染水平,部分化合物会通过饮水对儿童产生健康风险。通过研究,该流域PAHs整体污染程度中等,但是对流域居民的健康会产生风险,需要进一步制定相应的措施控制污染源,提升水环境质量。To know the contamination characteristics of PAHs in Lake Hasuhai,the probable sources of PAHs in the lake were analyzed by characteristic ratio method.The ecological risk of the target was evaluated by the risk entropy method and the health risk assessment model.The results showed that 9 PAHs were detected in the water,ranged from 269.79 ng·L^(-1) to 1340.69 ng·L^(-1).The main source was oil leakage mixed with fuel combustion emissions.33.33%of sampling cites in the lake were seriously polluted.Through oral,the health risk to children could not be ignored.The results proved that the pollution situation of PAHs in the basin was medium,but risks to the health of the residents in the basin still remained.It was necessary to formulate corresponding measures to control the pollution sources,improve the quality of water environment.
