摘要：
Polycyclic aromatic hydrocarbons (PAHs), widespread environmental pollutants, have been measured in aerosols and dustfall in Macao. In this paper, we compare concentration distributions and determine the partitioning of PAHs in aerosols and dustfall for different areas, sampling times and sampling heights. The results demonstrate that the concentrations of ΣPAHs in aerosols and dustfall vary at the different sites and heights. The concentrations of ΣPAHs and most of the individual PAHs in aerosols at night were higher than those in the daytime when using the unit of μg/g and lower than those when using the unit of μg m-3. It is shown that the distribution of individual PAHs in aerosols differs significantly from that in dustfall.
