Resumen:
Abstract Polycyclic aromatic hydrocarbons (PAHs) are considered potentially toxic, even carcinogenic, because of their afection to public health and the environment. It is necessary to know their ambient levels and the origin of these pollutants in order to mitigate them.A concerning scenario is the one in which commercial/administrative, industrial, and residentialactivities coexist.In this context, Gran La Plata (Argentina) presents such characteristics, in addition to thepresence of one of the most important petrochemical complexes in the country and intense vehicular traic.The source apportionment of PAH emission in the region, associated to 10-µm and 2.5µmparticulate matter fractions , was studied. First, different missing value imputation methods wereevaluated for PAH databases.GSimp presented a better performance, with mean concentrations of ∑PAHs of 65.8 ± 40.2 ng m in PM2.5. For both fractions, it was found that the highest contribution was associated with low molecular weight PAHs (3 rings), with higher concentrations −3 in PM10 and 39.5 ± 18.0 ng m −3
