Abstract:

In order to evaluate the contaminated status of PAHs in the agricultural soil of middle part of Jilin Province, the PAHs concentration of agricultural soil was systematically analyzed and the distribution and ecologic risk of PAHs were discussed. The results showed that the content of PAHs in the agricultural soil ranges between 144.5 μg/kg and 2 355.0 μg/kg, and the PAHs concentration of paddy soil is higher than that of dry farmland. The PAHs of soil mainly come from combustion of fossil fuel and petroleum plllution sources.The soil in this area is weakly contaminated by PAHs at present and it is showed that the ecologic risk of soil PAHs in this area is small.

Key words: polycyclic aromatic hrolrocarbons, agricultural soil, distribution, risk evaluation, Jilin Province
