Total suspended particulates (TSP) samples were collected from Sep., 2003 to Jul., 2004 in Beijing, and 15 kinds of PAHs, ranging from 3 to 7 rings were analyzed. The maximum concentrations sigma PAHs and BaP were 705 ng/m3 and 52 ng/m3 respectively. Average sigma PAHs concentrations in four seasons were 46 ng/m3, 16 ng/m3, 52 ng/m3 and 268 ng/m3 respectively; and the average BaP concentrations in four seasons were 2.8 ng/m3, 0.23 ng/m3, 3.3 ng/m3, 16 ng/m3 respectively. Regarding to the meteorological parameters, precipitation distinctly lowered the concentration; in heating period, PAHs concentrations fall with the temperature goes up, but there is no obvious relation between concentration and temperature in non-heating period; the increase of wind speed level causes the decrease of PAH concentrations in the heating period, but relation between PAH concentrations and wind speed varied with aromatic rings of PAHs and levels of wind speed in the non-heating period.
