Abstract
A profile of the soil samples around a typical crude oil sludge storage site of Jianghan Oil Field of China were collected and analyzed. We used the UE-GC/FID method to analyze qualitatively and quantitatively the 16 kinds of PAHs which were controlled priory by the U.S.EPA. The results showed that the study area was polluted severely by PAHs. The main pollutants were naphthalene, acenaphthylene, fluorene, phenathrene, chrysene, benzo(b) fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno (1,2,3,-cd) pyrene, dibenzo (a,h) anthracene, benzo (g,h,i) perylene, while the amount of acenaphthene, fluoranthene, pyrene and benzo (a) anthracene was relatively low. The peak values of PAHs in the profiles appeared in the range of 30-40 cm, was 1899 ng·g-1. The ability of different PAHs components to transport downward changed in the profile, which was characterized as 2 rings PAHs>3 rings PAHs>4 rings PAHs>5 rings PAHs>6 rings PAHs.
