Analysis of Distribution Characteristics of Heavy Metals in Soil of Bayi District-Gongbujiangda Road Section in Linzhi
Taking Linla high-grade highway as the investigation object,the surface soil beside the highway was investigated and its distribution characteristics were analyzed.The section from Bayi District to Gongbujiangda in Linzhi is more representative.The soil samples were digested with mixed acids,and the contents of heavy metals Pb,Cr,Zn,Cd,Mn and Cu in the soil samples along the highway were determined by atomic absorption spectrophotometry.The results showed that the soil of the highway from Bayi District to Gongbujiangda in Linzhi was polluted by heavy metals in different degrees,among which the pollution level of cadmium was serious,the pollution level of chromium was the lightest,and the other heavy metals were slightly polluted in different degrees,and the pollution degree was from low to high Zn<Cu<Pb<Mn.According to the correlation analysis of metal content,the results showed that the pollution of Cu,Pd and Cr may be homologous pollution,but the pollution of Zn and Cd was homologous pollution.
