Pollution Characteristics and Source Analysis of Polycyclic Aromatic Hydrocarbons in Surface Water in Qingyuan Basin of Hunhe River
The pollution characteristics such as content,composition,and distribution of 16 polycyclic aromatic hydrocarbon(PAHs)compounds in Qingyuan Basin of Hunhe River were studied,and their pollution sources were analyzed using the characteristic ratio method.The results showed that the range of total PAHs in surface water of the upper Qingyuan section of Hunhe River was 176.49～4 899.83 ng·L-1,and the mean value of total PAHs content was 953.51 ng·L-1.3 and 4-ring PAHs were the main components of PAHs in the sampling points.The main sources of PAHs pollution in this basin were biomass and coal combustion,and this result was consistent with the local production,and living reality.
