| Abstract: | The pollution degree of priority PAHs in aerosols at different function areas of main cities of PearlRiver Delta economic region is assessed with the standards of made public by WHO and regional background of priority PAHs in aerosols in Pearl River Delta economic region in spring. It is shown that the concentrations and pollution degreeof priority PAHs in aerosols in winter and spring were higher than those in summer at the same function area. It is considered that there were serious pollution of PAHs at complex area of commerce, crowded population and traffic, and pollution of PAHs at individual area of commerce, crowded population and traffic and light pollution of PAHs at industrial area in winter and spring. It is believed that the pollution degree of priority PAHs in aerosols at industrial area was greater than that at individual function area of commerce and traffic. A trial formula of multi parameter and suggestion that monitoring organic toxic pollutants must be enhanced based on conventional air environmental monitoring are presented in this paper. |
