Investigação sobre a emissão e caracterização dos hicrocarbonetos policiclicos aromaticos (HPA) na bacia do rio Atibaia

TL;DRAbstract

In this work, 18 PAHs were analyzed in sediments as well as in the suspended particulated matter in seven sampling points distributed along the Atibaia river basin during four sampling campaigns.Results show higher PAHs concentration during the dry season.The most impacted sampling point was at the Campinas potable water withdraw station with PAHs total concentration of 1.841 µg kg -1 dry weight in the dry season, and the least impacted one was the sampling point located downstream of the Anhumas input in the Atibaia river, with PAHs total concentration of 152,7 µg kg -1 dry weight during the rainy season.Sewage inputs were observed in the Atibaia river basin due to the predominance of fluoranthene, phenanthrene, pyrene and 2-methylnaphthalene.In the sampling point located near the SP-332 highway, PAHs from mobile sources were observed, mainly by heavy-duty diesel trucks.The Paulínia oil refinery (REPLAN) effluent analysys showed a daily total PAHs input of 6,5 g in the Atibaia river,
