Source apportionment model for PAHs in a complex urban area

The present analysis was carried out to test a method for extracting information from outputs of incomplete experimental frameworks. The method is based on the definition of an imputation vector based on the Box Model assumptions, and is applied to the identification of sources of polycyclic aromatic hydrocarbons (PAHs). Even if the data set showed that the sampling site was set in a non favourable point with respect to the winds scenario, the method provided important information, allowing to identify the angular location of major sources. The present analysis can be suitably carried out for selecting a suitable interpretative dispersion model, as much as an optimal location for new sampling stations.
