Acerra's air quality faces significant challenges from the densely urbanised Naples metropolitan area combined with the notorious Campania "Land of Fires" illegal waste burning legacy historically generating some of Italy's highest dioxin and PM2.5 concentrations. Vehicle traffic on the A1 motorway and surrounding industrial character compound the Campanian volcanic plain's enclosed geography, while the Naples Airport flight path nearby contributes aviation NOₓ to the broader Acerra metropolitan exposure throughout the year.
