摘要
采集安徽省部分矿区附近农田土壤样品，分析了重金属含量。结果表明：土壤总Cu、Zn、Pb和Cd含量分别为79．3～2415．3、75．6～778．6、46．3～252．1和O．29～13．546mg／kg，平均为282．1、功．2、122．5和1．927mg／kg，是我国A层土壤算术平均值的12．5、3．1、4．7和19．9倍。土壤Cu、Cd、Zn和Pb的污染指数相应为1．59～48．31、0．97～45．15、0．38～3．89和0．19～1.01，平均为5．64、6．42、1．14和0．45，表明该区域土壤已受到极为严重的Cu、Cd污染，部分土壤受到一定程度的Zn污染。
Soil samples were collected in the farmland near mining in Anhui province and the content of heavy metal was analyzed. The results showed that the total content of Cu, Zn, Pb and Cd was 79.3- 2 415.3,75.6 - 778.6,46.3 - 252.1 and 0.29 - 13. 546 mg/kg with the average of 282.1,227.2, 122.5 and 1.927 mg/kg,mspectively,which was 12.5,3.1,4.7 and 19.9 times of the one of the arithmetic mean of A-layer soils in China. The pollution index for Cu,Cd,Zn and Pb was 1.59 - 48.31,0.97 - 45.15,0.38 - 3.89 and 0.19 - 1.01 with the mean of 5.64,6.42, 1. 14 and 0.45 .Thus, the soil at this district was seriously polluted by Cd and Cu and a part of them was contaminated by Zn.
