[Concentration characteristics and influencing factors of atmospheric polycyclic aromatic hydrocarbons in TSP in the southeastern suburb of Beijing, China].
ATSP samples were collected at three sampling sites in the southeastern suburb of Beijing from March, 2005 to January, 2006. The samples were analyzed for TSP and sixteen PAHs. The concentrations and seasonal changes of TSP and sixteen PAHs were illustrated. Concentrations of sigma 16PAHs range from 0.29 - 1 184.48 ng/m3, and the average value is 239.44 ng/m3. Partial correlation analysis was applied to investigate the influence of meteorological parameters (temperature, wind speed, air pressure and relative humidity) and air pollution indexes (SO2, NO2 and PM10) on PAHs concentrations. Finally, quantitative estimation equations between PAHs and meteorological parameters and air pollution indexes were put forward by applying stepwise linear regression method, and the equations are sigma 16PAHs = 572.56 - 23.18 t and sigma 16PAHs = 5.99 SO2, respectively. Concentration of PAHs could be estimated using temperature or API of SO2.
