This study aims to investigate the air quality in primary school placed in district of Taranto (south of Italy), an area of high environmental risk because of closeness between large industrial complex and urban settlement. The chemical characterization of PM2.5 was performed to identify origin of pollutants detected inside school and the comparison between indoor and outdoor levels of PAHs and metals allowed evaluating intrusion of outdoor pollutants or the existence of specific indoor sources. The results showed that the indoor and outdoor levels of PM2.5, BaP, Cd, Ni, As, and Pb never exceeded the target values issued by World Health Organization (WHO). Nevertheless, high metals and PAHs concentrations were detected especially when school were downwind to the steel plant. The I/O ratio showed the impact of outdoor pollutants, especially of industrial markers as Fe, Mn, Zn, and Pb, on indoor air quality. This result was confirmed by values of diagnostic ratio as B(a)P/B(g)P, IP/(IP + BgP), BaP/Chry, and BaP/(BaP + Chry), which showed range characteristics of coke and coal combustion. However, Ni and As showed I/O ratio of 2.5 and 1.4, respectively, suggesting the presence of indoor sources. © 2017 A. Di Gilio et al.

The chemical composition of PM 10 samples collected during a monitoring campaign performed at five Apulia Region sites (Torchiarolo, Galatina, Taranto-Tamburi, Palagiano and Montalbano-Ostuni) was investigated. Ionic fraction, metals, carbonaceous compounds and polycyclic aromatic hydrocarbons (PAHs) were determined for all samples. The PM concentrations showed a regional background of PM 10 at all the sites except for Taranto and Torchiarolo which are characterized by an important industrial area close to the town and by a local biomass burning source, respectively. A principal component analysis (PCA) applied to the dataset provided four sources relevant for the area under investigation, that were identified as combustion processes, crustal, marine aerosol and secondary particulate matter. The integrated approach used in this work (chemical characterization of the samples, meteorological information and statistical analysis) allowed to evaluate the synergistic effect of regional secondary particulate and long-transport contributions to PM 10 concentrations at the sampling sites and to provide useful information in order to characterize the most relevant local emission sources.
