The content of cadmium(Cd) was investigated in the farmland of water level fluctuating zone of Zhuxi River.The results showed that the content of Cd in farmland exceeded GradeⅢof the national environmental quality standard,which also exceeded the soil background value in Sichuan Province.Cd was accumulated in different plant parts of crops,among which leaves had the maximum bioconcentration ability(BCA),and fruits had the minimum BCA.Overall,BCA in edible parts was in the order of water spinach>coriander herb>peanut>cowpea>mung bean.Water spinach and coriander herb would bring potential health risk to local residents with HQ>1.
