摘要
According to "Environmental quality standard for soil" and using As,Cd,Cr,Cu,Hg,Ni,Pb,Zn elements as evaluation index,the author evaluated soil environmental quality in Xihe area of Shenyang.The results show that the soil in Xihe area is polluted rifely by heavy metal elements.The polluted areas are mainly distributed near the upstreams of Xihe River,Shenxin River and Shenliao irrigation canal.There exist large distinctions among the heavy metal elements to the pollution degree.Cd pollution area is the biggest and the most serious in pollution degree.
According to ＂Environmental quality standard for soil＂ and using As, Cd, Cr, Cu, Hg, Ni, Pb, Zn elements as evaluation index, the author evaluated soil environmental quality in Xihe area of Shenyang. The results show that the soil in Xihe area is polluted rifely by heavy metal elements. The polluted areas are mainly distributed near the upstreams of Xihe River, Shenxin River and Shenliao irrigation canal. There exist large distinctions among the heavy metal elements to the pollution degree. Cd pollution area is the biggest and the most serious in pollution degree.
