Preliminary Research on Chrome Pollution in Farmland Surface Soil around Gold Mining Area

Abstract:

Zhaoyuan city, Shandong Province, is a city rich in mineral resources. In order to study the pollution characteristics of chrome in soil around gold mining area near Zhaoyuan City, the surface soil samples were gathered. The chrome content in soil samples was determined by atomic absorption spectrometric method. The results show that the range of chrome contents in surface soil around gold mining areas are from 7.54mg/kg to 54.23mg/kg, with the average content being 23.11mg/kg. There is an obvious positive correlation between the chrome contents in the surface soil samples and their corresponding value of the organic matter, and there is no relationship between the chrome content in soils and their corresponding value of pH and CEC. The result indicated that chrome pollution of surface soil in gold mining areas is not particularly serious.
