Abstract
As the "source" and "collector" of PAHs, surface dust in cities, cause invisible, potential and long-term destructions to ecosystems. PAHs content in the surface dust and distributions of functional areas in Shenyang city was discussed systematically. PAHs composition differences in different functional areas were analysed. It was concluded that parks and residential districts present the least PAHs pollution, while commercial districts and roads suffer the heaviest PAHs pollution. Different functional areas show similar composition of PAHs. Most PAHs are high-ring ones, accompanied with some low-ring PAHs. The content of high-ring PAHs is proportional to the number of rings or molecular weight. PAHs pollution and health risk in Shenyang city were evaluated through various methods. Results demonstrated that PAHs pollution in Shenyang city has reached a high level, which is threatening the local ecological environment and human health significantly.
