| 摘 要： | 随着工业化和城市化进程的推进,行业环境重金属污染日益受到关注。选取北京市10个典型行业地表环境灰尘为研究对象,分析了灰尘不同粒径分布和Pb、Cr、Cu、Zn、Ni浓度及贡献率,并采用单因素污染指数和综合污染指数法评估了重金属在不同行业地表环境的污染水平。结果表明:批发行业、工业、餐饮业和交通运输业综合污染水平较高,文化体育业和教育行业综合污染水平最低。

| Abstract: | With the promotion of industrialization and urbanization，much attention is being paid to heavy metal pollution of
the industry environment． The dusts from 10 typical industries environments in Beijing were selected as the research objects，
the different particle size distribution of the dusts，Pb，Cr，Cu，Zn，Ni concentration and contribution rate were analyzed． The
heavy metal pollution levels in the surface environment of different industries were evaluated by means of the single factor
pollution index and comprehensive pollution index． The results show that the comprehensive pollution levels of the wholesale
industry，industry，catering industry and transportation industry are high，culture and sports industry and education industry
are relatively low． |
