Catullo Spa implements measurements carried out to monitor air quality that go further than those provided for by the regulations, in order to safeguard the urban settlements located in the proximity of the airport grounds. The analysis (referring to the measurement campaign conducted from 26 February to 29 May 2013 by the Veneto Regional Agency for Environmental Protection and Prevention) indicates that the values of the main polluting agents have always remained below the limits established by law, or are in any case comparable to the values identified in other areas of the province and the region.
