The contents and sources of 16 kinds of polycyclic aromatic hydrocarbons（PAHs），which are on
the list of priority control PAHs stated by USEPA，in soils from 4 traditional vegetable production bases of Nanning
City were analyzed by HPLC. The result showed that the content ranges of PAHs in soils of vegetable production
bases of Nanning City were 2 632.00～5 002.43 μg·kg-1 dry weight and the average value is 3 351.30±1 110.72
μg·kg-1. The PAHs pollution in soils was in severe polluted level. Most of PAHs in soil contained 2～4 aromatic
rings，and the content took 85.72% of the total PAHs content，among which PAHs of 3 aromatic rings occupied
the largest proportion 54.62%. The PAHs in vegetable production soil of Nanning City were mainly due to the
burning of biomass and fossil fuel and emission of motor vehicle exhaust.
