Abstract

Rain water may collect organic air pollutants, such as polycyclic aromatic hydrocarbons (PAHs), phthalate ester (PEs), pesticides, and polychrorinated biphenyls (PCBs), that could be present in air in consequence of different factors. The determination of these compounds in rain water samples consequently may be interesting for a first screening of air quality in urban and/or industrial areas. For this purpose, 3 areas of the city of Rieti (central Italy) were selected for rain water sampling: a) the city center, densely populated and with high road traffic; b) a suburban residential area; c) the industrial area, about 3 km out of the city center and along the state road. Wet-only precipitation collectors were used for sampling; solid-phase microextraction or liquid-liquid microextraction techniques followed by GC/MS determinations were applied for sample analysis. PCBs and pesticides were never found in the samples collected. On the contrary, some polycyclic aromatic hydrocarbons and phthalates were always found. Significant and seasonal differences in PAH levels were observed in the 3 different sampling areas, with higher values always found in the city center and during the winter period; on the contrary, PEs levels remained unchanged.
