A survey of paired soil-rice (n = 200) and soil-vegetable (n = 142) samples was conducted in Xiangtan county of Hunan province, southern China. The concentrations of Cd in all the samples were determined by inductively coupled plasma mass spectrometry. Dietary intakes of Cd from the consumption of locally produced rice and vegetables were estimated for different age groups. Among the 342 crop samples collected in the survey, 88% and 29% of rice grain and vegetable samples, respectively, exceeded the Chinese maximum permissible limit for Cd (0.2 mg dry weight kg−1, 0.2 mg fresh weight kg−1 and 0.1 mg fresh weight kg−1 for rice, leafy vegetables and for rootstalk and legume vegetables, respectively). The median dietary Cd intake varied …
