The use of passive samplers for monitoring polycyclic aromatic hydrocarbons in ambient air

摘要: In this study polcyclic aromatic hydrocarbon (PAH) concentrations of ambient air are compared to those present in leaves, spruce sprouts and the corresponding soil used as passive samplers. Marked profile alterations were detected various horizons with increasing relative higher boiling decreasing lower PAH depth. There is no direct correlation between absolute masses found samples collected by samplers or samples. Even profiles differ significantly; they can, however, be correlated introducing PAH- sampler-specific factors. The appear indicate that coal combustion mostly contributes pollution FRG. time course concentration benzo[a]pyrene benzo[e]pyrene during past seven years measured biological sampler a significant decrease (by factor two) First measurements clean area Eastern part FRG exhibited up ten times than comparable areas western country.
