Pollution characteristics of heavy metals in farmland soil around a lead-zinc smelting plant in western Guanzhong Plain
摘要
Abstract
Through the methods of field sampling and experimental analysis ,the contents of heavy metals in farm-land soil around a lead-zinc smelting plant in western Guanzhong Plain were investigated and the pollution assessment was conducted .The results showed that the contents of Pb ,Zn ,Cu ,Cd ,Cr ,Hg ,As and Ni were 47 .95 ,128 .53 ,26 .13 , 1 .09 ,91 .5 ,0 .164 ,12 .2 mg・kg - 1and 27 .1 mg・kg - 1 ,respectively .Except for Ni ,the contents of all other elements were higher than the soil background values in Shaanxi Province .The assessment results showed that the pollution of heavy metals in the farmland soil around the lead-zinc smelting plant was moderate or serious ,in which the pollution of Pb ,Hg and Zn was serious ,and the comprehensive pollution in the farmland soil was serious .关键词
