Concentrations of benzene, CO, NO2, O3 and PM10 in urban atmosphere of Genoa have been analysed from roadside air pollution monitoring sites in order to identify the presence of eventual critical situations and adverse health effects in exposed workers such as urban traffic vigilants. The monitoring campaign, monthly performed by ARPA technicians from 2005 to 2009, shows higher pollution phenomena in the center of urban area, sites 2,6 and 8. The obtained data have been statistically evaluated and correlated among themselves and with the pulmonary functions of urban traffic vigilants (ANOVA uni- and multivariate). No critical situation appears as far as the average concentrations of atmospheric pollutants are concerned and the key indicators of lung functions too (FVC, MVV, FEV1, FEF25, FEF50, FEF75); the observation regards values collected at the beginning and the end of the campaign. At last statistical analysis demonstrates decreasing values of MEF75 connected with sites 2, 6 and 8 (P respectively= 0,06, 0,07, 0,09) to confirm that the central sites represent critical zones. However this observations is not particularly significant becouse involves only hight respiratory tracts, in absence of chronic pulmonary syntoms or diseases, and a further investigation on a larger pattern is requested.
