ΣPAH accounted for 0.0018% of the TSP mass and 0.0012% of the PM10 mass. Total PAH contents on the particle phase were 3.57 ng m-3 and 2.59 ng m-3 for TSP and PM10, respectively. Contributions of carcinogenic USEPA priority PAHs (B[a]An, B[b]F, B[k]F, B[a]Py, IPy and DB[ah]A) were 1.86 ng m-3 (52% of total PAHs) and 1.40 ng m-3 (54% of total PAHs), for TSP and PM10 samples, respectively. Diagnostic ratios and multivariate statistical analysis were, in general, similar to those reported for soil dust except for the Flt/Flt+Py) ratio, 0.34, compatible with diesel emissions. Dry deposition fluxes were in the range of 0.022-0.603 and 0.016-0.436 μg m-2 day-1 for compounds in TSP and PM10, respectively.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-05-17T13:28:35Z No. of bitstreams: 1 __www.scielo.br_pdf_jbchs_v20n9_02.pdf: 164837 bytes, checksum: 34ffd92b134786c97ae1cfc444a01919 (MD5)Made available in DSpace on 2012-05-17T13:28:35Z (GMT).
