Abstract
In the frame of the project EDOC@WORK3.0, Education and Work on Cloud (2013-2015) founded by MIUR (Italian Ministry for University and Research), a monitoring plan has been carried out in Taranto (one of the most polluted sites of Italy) [1] in order to investigate contemporary indoor and outdoor concentrations of NO2 and SO2 by passive sampling devises (Radiello sampling system) [2]. In Taranto (South Italy), close to the urban centre, an industrial complex, that includes one of the greatest steel manufacturing plants in Europe, an oil refinery, shipbuilding activities, a navy arsenal and a cement plant and two thermoelectric power plants has host [1]. These industrial activities represent important environmental stressors for the area. Simultaneously indoor and outdoor samplings of NO2 and SO2 were performed from 2n November 2015 to 5 December 2015 in nine sites scattered in the area: three sites were located in the downtown, two sites in the district Tamburi, very close to the industrial area, one site closeness to the high traffic street, two in the district 'Paolo VI' and one in Statte (a municipality very close to the industrial complex).
