Results of the investigation and analysis of the soil in a well-industrialized and urbanized city in South Jiangsu showed that the single-factor pollution index with HCH was the lowest, and followed by that with Pb and Cr whereas that with Cd was the highest; however, in some traditional vegetable fields and vegetable fields in greenhouse, the single-factor pollution index with DDT came close to or over 1, indicating DDT residues exceeded the criteria in some of the soils. In regard to combined pollution index, except paddy soil with the value being 0.57, below the threshold value of 0.7, all the soils ranged between 0.72 and 0.95, all beyond the threshold value for warning. In the studied area, over 20% of the soils had their combined pollution indices beyond 1, suggesting that the soils are slightly polluted, which should arouse attention from competent authorities.
