Distribution and Sources of Polycyclic Aromatic Hydrocarbons in Soils of Huzhou City

A total of 74 surface soil samples were collected and analyzed for polycyclic aromatic hydrocarbons (PAHs) and the contents and pollution levels of 15 PAH compounds in different types of surface soils of Huzhou were studied. Results show that the highest contents of PAHs could be found in Huzhou urban. The ratio of low circle PAHs/high circle PAHs were less than 1, and the ratio of Pyrene/Benzo (a)pyrene were less than 2. This means that the PAHs pollution in Huzhou soils was mainly from the burning coal and domestic pollution.
