The data of the air quality monitoring in Venice led by Arpav in collaboration with the Municipality of Venice are ready. nitrogen dioxide is an hourly parameter that in some sites deserves attention: in fact, even though the weekly average concentrations in all sites have never exceeded the limit values ​​and the overall average resulted as limit values ​​in both winter and summer and at the limit value in all sites, in the immediate vicinity of the Grand Canal, characterized by intense water traffic, higher concentrations of NO2 are recorded but in any case below the annual limit value. At the Rio Novo site, lower concentrations were measured only considering those detected along the Grand Canal and San Marco: therefore the entire historic center, being the representative site of a medium – high water traffic situation, unlike the more specific and less representative of the Grand Canal, which is unique in all of Venice; these results confirm the advisability of maintaining a fixed station in said position. Sulfur dioxide is not found in any of the monitored sites: the weekly average concentrations were well below the limit values ​​at all the monitoring stations in the Province of Venice and the overall average of the concentrations measured in the two winter and summer periods was between 1.3 and 2.2 µg / m3, measured respectively at Rio San Zan Degolà and at Ferrovia; these are values ​​well below the limit for the protection of ecosystems.
