摘要

This study chooses the industrial wasteland after the relocation of a metal processing factory in Shenyang, Liaoning Province of China as the research object. Based on level three soil heavy metal quality standards of Soil Environment Quality Standard (GB15618-1995) in China, the pollution levels of four heavy metals (cadmium, lead, copper and zinc) in survey area are Cd＞ Cu＞ Zn＞ Pb; the Cd pollution is the most serious one, followed by Cu and Zn. The Pb content is low. Average comprehensive pollution index of Cd, Cu, Zn and Pb in soil of the wasteland is 17.33, which belong to Grade V severe pollution. The most polluted point is J-12, followed by J-11 and J-16. The land utilization risk assessment of the wasteland should be strengthened, and appropriate and necessary repair measures should be taken, such as planting accumulative or tolerant plants.
