Abstract:The content of Cu,Pb and Cd on vegetables in Yancheng city was analyzed and assessed by single-facter pollution index.The measurable rate of copper was 89.5%,and no sample site exceeded the concentration of official tolerance.The measurable rate of zinc was 94.7%,and all matched the standard.The measurable rate of cadmium was 44.2%,and 3.16%,which exceeded the standard.The order of the content of heavy metal in vegetables was Zn>Cu>Cd.The vegetables in Yancheng city had not be polluted by copper and zinc,and seldom of them had be polluted by cadmium.
Keywords:vegetables   heavy metals   pollution   pollution index   Yancheng city
