Abstract: The contents of heavy metal (Pb, Cd, Cr, Hg) in the vegetable soils collected from the main vegetable production areas in north of Anhui province were examined and analyzed to evaluate the vegetable soils status of heavy metal contamination. The evaluation of environmental quality of the vegetable soils was carried out by using the Nemerow index method. The results showed that the mean contents of Pb, Cd, Cr, Hg of the vegetable soils in of north Anhui were 22.5, 0.247, 63.2, 0.040 mg/kg and the mean integrated heavy metal pollution index of the vegetable soils was 0.64. The vegetable soils were good in quality on the whole. Some of the vegetable soils were polluted with heavy metals, Cd and Hg were the major pollution contributors. The contents of Cd and Hg were significantly correlated with soil total P,available P and the time of plating vegetables.
