摘要: The contributions of deposited particles (P) to polycyclic aromatic hydrocarbon (PAH) levels in pine (Cedrus deodar) needles sampled from the Dalian region were evaluated by washing off needle surfaces. P values ranged 4.4 ± 2.2% for fluorene 69.9 4.0% indeno(1,2,3-cd)pyrene, and positively correlated with logarithm octanol–air partition coefficients (log KOA) each PAH significantly. total 14 PAHs under study (∑PAHs), that 490 3241 ng g−1 dw (dry weight) median value 1521 dw, high traffic areas, low residential or park implying significant both gas particle phases emitted vehicles. However, profiles not significantly altered washing, due fractions (2–5%) 5- 6-ring ∑PAHs. wind speed frequently alternating directions spring could quicken depuration processes PAHs. Thus, local meteorological conditions source variations should be taken into account when using implicate seasonal atmospheric semi-volatile organic compounds.
