The Environmental Engineering Laboratory (EEL) of the Department of Civil Engineering of the University of Patras has conducted a project for assessing the University of Patras Campus (UPC) air quality. This project has started on April 2012, after a meeting of the University Committee for Environmental Management. The EEL Monitoring Station has been installed 18-m W from the building of Civil Engineering Department. It is equipped with automatic analyzers for particulate matter (PM10, PM2.5 and PM1), sulfur dioxide (SO2), carbon monoxide (CO), oxides of nitrogen (NO, NO2 and NOx) and ozone (O3), as well as for necessary meteorological parameters. The air pollution measurements at UPC site for the period 2012-2013 are presented in the present book in comparison to the limit values and available corresponding data of other Hellenic and European Mediterranean sites of approximately same latitudes. It is concluded that UPC site is convenient for monitoring secondary air pollution, while primary air pollution is not a matter. Comparisons reveal that UPC resembles suburban and rural sites. Data are very useful for assessing environmental impacts due to future development of the area.
