| Abstract: | Contents of heavy metals Hg,As,Cd,Cr,Pb and Cu at seven pollution-free agriculture product bases in Zhijin County were analyzed and environmental quality of the soil was assessed by using the single-factor contaminant index and comprehensive pollution index methods.The results showed that the single-factor contaminant index of Cd at five bases exceeded the warning level,while that of Cu at one base exceeded and at another,lightly polluted.All comprehensive pollution index was under 1.0,meating requirements ... |
