It is considerably important for sustainable development of nonferrous metals industry to study the soil environmental quality and food safety in the typical bined pollution belts. In this study, cultivated soil, vegetable and rice samples were collected from the nonferrous industry areas, including Changsha, Zhuzhou, Hengyang and Chenzhou district of Hunan Province. Accumulation and translation characteristics of heavy metals in the cultivated soil, vegetable and rice samples were determined, and, potential risk of heavy metals in vegetables and rice for human’s health was evaluated through principle ponent analysis, multivariate techniques and correlative analysis. The results show that the cultivated soils are mainly contaminated by Cd, As, Pb, Cu and Zn. Combined pollution information of Pb, Zn, Cd and As in vegetable soils and the relationship among them with pH of vegetable soils and, of Cu, Zn, Pb and Cd in paddy soils from factor 1 is elucidated through principle ponent analysis, respectively. Furthermore, bined pollution for cultivated soils is elucidated mainly by Cd, Pb, As, Cu and Zn through multivariate techniques, too. Concentrations of Cd, Pb, As, Cu, Zn and Cr in vegetables, and of Cd, Pb and Zn in rice from the studied areas are much higher than the threshold level of food quality of China. Especially, concentrations of Cd, Pb, and As in vegetables and, of Cd and Pb in rice are heavily potential risk for human’s health.Key words: nonferrous metals industry areas。 vegetable。 multivariate analysis
