摘要

调查了安微省蚌埠市文教区、居民区、商业区、公园绿地区、工业区、交通区6个功能区的地表灰尘中重金属Zn

Mn的含量

并采用地累积指数法和Hakanson潜在生态危害指数法评价了重金属污染程度及潜在生态风险。结果表明

蚌埠市地表灰尘中Zn

Cd和Mn平均含量依次为:254.29

85.64

72.39

2.31和535.86 mg/kg

均高于安徽省土壤环境背景值。地累积指数法评价结果显示

Cd元素为偏重污染;Zn和Cu为偏中度污染;Pb为轻度污染;Mn处于清洁水平。所研究的6个功能区均属于偏中度污染。潜在生态危害指数法评价结果表明

Cd元素污染最严重

在所有采样点均超出强生态危害水平

其他4种重金属元素均属于轻微生态危害。交通区、商业区、居民区和工业区属于很强生态危害程度

文教区和公园绿地区处于强生态危害水平。在去除重金属Cd以后

各功能区均表现为轻微生态危害水平。总之

蚌埠市地表灰尘重金属的生态环境较好

但存在Cd元素的极强潜在生态危害。

Abstract

The concentrations of heavy metals(Zn

Cd and Mn) are investigated in surface dusts of Bengbu City

Anhui Province. The geo-accumulation index and the Hakanson potential ecological risk index are employed to evaluate the pollution degree of heavy metals in the surface dusts and the level of potential ecological risks. Results show that the average contents of Zn

Cd and Mn in the surface dusts are 254.29

85.64

72.39

2.31 and 535.86 mg/kg

respectively. The concentrations of the heavy metals are higher than their soil background values in Anhui Province. The evaluation results of geo-accumulation indicate that Cd is of partial heavy pollution

Zn and Cu are of partial mild pollution

Pb is of light pollution

and Mn is in clean level. All functional areas are in partial moderate pollution. Assessment results of the potential ecological risks indicate that Cd pollution is the most serious

beyond the strong ecological risk level in all sampling points. The other four heavy metals are in slight ecological risk. The sampling points in traffic

business

residential and industrial districts belong to very strong ecological risk degree and other sampling points are in strong ecological risk. After the removal of heavy metal Cd

various functional areas are in slight ecological risk. In general

the situation of surface dusts of Bengbu City is in a good ecological environment. However there is the very strong potential ecological risk for Cd.
