Resumo: | We measured polycyclic aromatic hydrocarbons (PAHs) in bulk precipitation in the Fortaleza metropolitan area, Ceará, Brazil, for the first time. Because little information is available concerning PAHs in tropical climat- ic regions, we assessed their spatial distribution and possible sources and the influence of urban activities on the depositional fluxes of PAHs in bulk precipitation. The concentrations of individual and total PAHs (ΣPAHs) in bulk precipitation ranged from undetectable to 133.9 ng.L− 1 and from 202.6 to 674.8 ng.L− 1, respectively. The plume of highest concentrations was most intense in a zone with heavy automobile traffic and favorable topography for the concentration of emitted pollutants. The depositional fluxes of PAHs in bulk precipitation calculated in this study (undetectable to 0.87 μg.m− 2.month− 1) are 4 to 27 times smaller than those reported from tourist sites and industrial and urban areas in the Northern Hemisphere. Diagnostic ratio an- alyses of PAH samples showed that the major source of emissions is gasoline exhaust, with a small percentageoriginating from diesel fuel. Contributions from coal and wood combustion were also found. Major economicactivities appear to contribute to pollutant emission |
