摘要
对上海市内环高架沿线街道灰尘重金属污染进行了调查,结果表明,与道路交通因素相关的重金属Pb、Cd、Cu和Zn均具有较高的含量水平,分别为上海市土壤背景值的9.3倍,7.5倍,9.0倍和8.8倍。除了重金属Hg以外,其他7种重金属平均含量均表现为浦西段高于浦东段,说明内环高架浦西段相对于浦东段具有较高的重金属积累。而污染指数评价的结果也表明了上述4种重金属的污染程度超过了其他重金属,已经达到了中度污染水平。
The pollution of heavy metal in street dust along inner-ring overhead highway in Shanghai was studied. The contents of Pb, Cd, Cu and Zn were higher levels and reached 9.3 times, 7.5 times, 9.0 times and 8.8 times of the soil background value in Shanghai city respectively. Except for Hg the contents of 7 heavy metals in Puxi district were higher than those in Pudong district to indicate higher heavy metals accumulation of west parts than east parts in the inner-ring overhead highway. The results of geo-accumulation index evaluation showed the Pb, Cd, Cu and Zn pollution had reached medium pollution levels.
