Abstract

Abstract

The distribution maps of heavy metals in soils of Chongming county were drawn using Kriging method in the geo-statistic module of ArcGIS，and the degrees of pollution were evaluated using the single-facter pollution index (SPI) and comprehensive pollution index (CPI).The results showed that the degrees of pollution of heavy metals in soils of Chongming County were CdZnCuCrPb. Among the heavy metals, Cd was the major one. The average SPI of Cd in the soil samples was 1.05, reaching the light degree of pollution.The comprehensive pollution index of 5 heavy metals including all soil samples, ranged from 0.22 to 2.59 with an average of 0.88, reaching the alarm degree of pollution. However, The overall situation of heavy metals in soils were relatively clean, because there were still 72.39% of soil samples showing the cleanness.
