| 摘 要： | 淀山湖地处上海的饮用水源地,水体中有机污染物的生态风险逐渐引起人们的重视。淀山湖水质监测结果显示,淀山湖中的挥发性有机物以二氯甲烷为主。应用美国环境保护署的AQUATOX模型对淀山湖水体中二氯甲烷进行模拟,并进行生态风险评价,旨在构建基于AQUATOX模型的水环境中有机物浓度模拟方法及风险评价的研究体系。结果显示,淀山湖中的二氯甲烷尚处于安全范围,但是需要加强观测,避免高风险的发生。 |
| 关 键 词： | 淀山湖 AQUATOX模型 暴露评价 生态风险评价 二氯甲烷 |

| Abstract: | Dianshan Lake is potable water source in shanghai,the ecological risk of organic pollutants in Dianshan Lake has brought great attention to people.The water quality monitoring results of Dianshan Lake show that dichloromethane is the main volatile organic in Dianshan Lake.The exposure assessment of the dichloromethane in Dianshan Lake was analyzed by the AQUATOX(USEPA) model,and the aquatic ecological risk assessment was also done.This paper was aimed to set up an AQUATOX model based research system for simulated the organic in the water and evaluate the ecological risk.The result shows that the concentration of dichloromethane in Dianshan Lake is still in a safe level,but it also need a long-term observation to avoid the dynamic high risk in Dianshan Lake. |
| Keywords: | Dianshan Lake AQUATOX model exposure assessment ecological risk assessments(ERA) dichloromethane |
