摘要：

Dietary exposure to heavy metals is threatening human health worldwide. In this study, the concentration of cadmium, mercury, arsenic and chromium in 258 samples of brown rice, grown in Yangtze River Delta where the soils were low-level contaminated, were investigated. In 12 (4.6%) and 10 (3.9%) rice samples the concentrations of Cd and Hg, respectively, exceeded the limit for food. ANOVA showed that Cd and Hg concentrations in rice grains collected from Nanjing and Jiaxing were higher than in the less developed city Yancheng. Students' t-test showed Cd and Hg were accumulated in hybrid rice higher than in conventional rice. The hazard quotients (HQs) showed a low risk from rice consumption. Conventional rice was recommended to cultivate to reduce the current risk in the soil defined as safe use level in Yangtze River Delta.
