摘要
目的调查北京市某涉铅企业对周边环境的影响,并对污染现状进行评价。方法在某涉铅企业周边采集空气、土壤和地下水样品,测定铅的浓度,通过单因子污染指数法和内梅罗综合污染指数法进行综合评价。结果采集空气、土壤和地下水样品分别为28、4和5件。经检测37件样品铅浓度均未发现超标情况,单因子污染指数均小于1,空气样品铅的内梅罗综合污染指数高于土壤样品。结论该企业未对周边环境造成严重的铅污染,但对空气的影响程度严重于土壤。
[Objective] To investigate the influence of lead （Pb） around a factory in Beijing, evaluate the pollution level. [ Methods ]The samples of air/soil/underground water were collected around a factory related to Pb. The concentrations of Pb were detected, and the results were evaluated by the single factor polluted index and N.L Nemerow integrated polluted index. [Results]There were 28 samples of air, 4 samples of soil and 5 samples of underground water. The levels of Pb from 37 samples were lower than the environmental standard limits, and all of the single factor polluted indexes were lower than 1. The N.L Nemerow integrated polluted index of air samples was higher than that of soil samples. [Conclusion]The Pb pollution of the factory for the surrounding environment is not serious, but the effect on air is worse than on soil.
