Contamination and control of heavy metals in farmland around coal mining area in Northern Shaanxi
To investigate the pollution of heavy metals on farmland around mining area during coal mining,sampled the heavy metals from surrounding soil and corn seedling in Shenmu Daliuta coal mine. Determined the heavy metals content of 35 typical sampling point and blank group.The results show that,the average content of Cu,Zn,Pb,Cr,Cd,Hg,As and others heavy metals are higher than those in the blank group,the content of Zn,Cu,Pb,Cr,Hg and others heavy metals in soil have positive correlation with those in the corn seedling.That means the soil around the mining area has been contaminated and the heavy metals in soil have a direct impact on the heavy metals absorp-tion of corn seedling.Provide matched soil remediation measures.
