Aviation-related impacts on UFP near airports

Aircraft engine exhaust emissions are a significant source of ultra fine particles (UFP; aerodynamic diameter <100 nm) and can cause several-fold increases in ground-level particle number concentrations (PNC) over large areas downwind of airports, as a recent study in the United States shows. Exposure to UFP is of particular concern because it is associated with […]

Noise tax in Northwest Italy

From 1 January 2018 the aircraft noise tax (Iresa) was introduced in Piedmont, Italy, giving an economic value to the weight, equal to € 0.50 per ton. This was decided at the meeting of the regional commission – which involved Finance and Transport – of 25 October last. The Conference of Regions, in 2012, had […]

Aircraft Noise and the Heart

Noise has been found associated with annoyance, stress, sleep disturbance, and impaired cognitive performance. Furthermore, epidemiological studies have found that environmental noise is associated with an increased incidence of arterial hypertension, myocardial infarction, heart failure, and stroke. Observational and translational studies indicate that especially night-time noise increases levels of stress hormones and vascular oxidative stress, […]
