Persistent Organic Pollutants (POPs) have become widespread in the environment and now represent a global contamination problem. The global transport of POPs is of current interest and concern. Based on the model of global fractionation and distillation, at present, the contributions of POPs from the subtropical regions of China to the pollution to the global environment are paid more and more attention. Recent investigations showed that POPs concentrations in the water, sediment, and atmosphere could be very high in the region. However, there have been few studies on POPs in agricultural ecosystems within this region. The U. S. EPA analytical methods were employed to examine agricultural soils concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) and organochlorine pesticides (OCPs) in typical area of subtropical zone of China.The distribution and main possible sources of these pollutants were studies. Contamination traits in different planting manner were discussed. The results were showed as follows: (1) The total PAHs concentrations ranged from 22.1ng/g to 1256.9 ng/g and the pollution extent was classified as a moderate level in comparison with other investigations and soil quality standards. PAHs isomer ratios suggested that the pyrolytic origins such as fossil fuel combustion related to vehicle exhaust as well as industrial emissions were the dominant source of PAHs. (2) The concentrations of OCPs ranged from 4.6ng/g to 1021.5 ng/g and DDTs and HCHs didn’t exceed national soil quality standards, suggesting that OCPs contamination still existed after forbidden for a considerable period. OCPs residues might be caused by its persistence and/or some fresh input of DDT and Endosulfan. (3) High PAHs and OCPs concentrations were found in surface and subsurface soils. The total concentrations were declined with depth，but transmission was little under 40cm. (4) The PAHs of vegetable soils were slighter than that of paddy soils, but the OCPs residues were more than ones of paddy soils.
