Residues and distribution of organochlorine pesticides in the soils of the vegetable garden in the southern Jiangsu were analyzed.The effects of soil utilization, cropping system, vegetable species and history of vegetable cultivation on residues of the pest icides were also discussed.A county with long history of vegetable plantat ion, developed in urbanization and industry, was selected as case study.89 samples were collected throughout the whole county with GPS value for each location.The results showed that organochlorine pesticides were found widely in the soils, with an occurrence of 100%.The mean of the total concentrations(∑-OCP) was 174.4 μg kg^-1 with a range of 23.2μg kg^-1~1126.7μg kg^-1.p, p'-DDE and p, p'-DDT are the main components and took over 82% of the total.The kailyard soil had the highest residues of ∑-DDT, while the paddy soils had the lowest levels.The residues varied significantly with vegetable species in kailyard soils.The residues in soils growing leaf vegetable were much higher than others.The rotation of vegetable and rice could decrease the risk of organochlorine pollution.
