摘要

Particulate matter (PM10 and PM2.5) concentrations were monitored during the November 2008 by using the filter samples collected day and night from three sites in Tanggu District at Tianjin Binhai New Area, China. The mean concentrations of PM2.5 and PM10 rank in the order of urban (150 μg/m3 for PM2.5 and 197 μg/m3 for PM10)industrial (32 μg/m3 for PM2.5 and 170 μg/m3 for PM10)suburb area (27 μg/m3 for PM2.5 and 59 μg/m3 for PM10). Sixteen polycyclic aromatic hydrocarbons (PAHs) were analyzed in PM10 and PM2.5 samples. Concentrations of total PAHs in PM2.5 and PM10 are in the range of 8.47–113.94 ng/m3 with average of 62.88 ng/m3 and 21.07–118.23 ng/m3 with average of 73.42 ng/m3, respectively. The light ring PAHs (2–4 rings) are dominant in both PM2.5 and PM10 during sampling time compares with the heavy ring (5–6 rings) PAHs. The relationship of PAHs and PM2.5 (r = 0.689, p0.05) is stronger than PAHs and PM10 (r = 0.570, p0.05), illustrating PAHs tend to adsorb in PM2.5. In addition, principal component analysis was applied to find the source of PAHs. Three principal factors representing three types of PAHs sources in Tanggu District are extracted, which were coke production, pyrogenic sources and vehicular source.
