%X the present work has aimed to determine the 16 us epa priority pah atmospheric particulate matter levels present in three sites around salvador, bahia: (i) lapa bus station, strongly impacted by heavy-duty diesel vehicles; (ii) aratu harbor, impacted by an intense movement of goods, and (iii) bananeira village on mar¨¦ island, a non vehicle-influenced site with activities such as handcraft work and fisheries. results indicated that bbf (0.130-6.85 ng m-3) is the pah with highest concentration in samples from aratu harbor and bananeira and cry (0.075-6.85 ng m-3) presented higher concentrations at lapa station. pah sources from studied sites were mainly of anthropogenic origin such as gasoline-fueled light-duty vehicles and diesel-fueled heavy-duty vehicles, discharges in the port, diesel burning from ships, dust ressuspension, indoor soot from cooking, and coal and wood combustion for energy production.
