Within the framework of the UN-ECE Convention on Long-Range Trans-boundary Air Pollution, critical ozone levels for forest trees and crops have been determined. This paper shows the mapping results of short and long-term threshold exceedances in an area of Central Italy. Eighty-thousand hourly mean ozone concentrations were recorded and computed to evaluate the potential distribution of the pollutant in the area. The results suggest that the threshold is frequently exceeded in the summer, and this may be very critical for the plants' health.

Abstract
Within the framework of the UN-ECE Convention on Long-Range Trans-boundary Air Pollution, critical ozone levels for forest trees and crops have been determined. This paper shows the mapping results of short and long-term threshold exceedances in an area of Central Italy. Eighty-thousand hourly mean ozone concentrations were recorded and computed to evaluate the potential distribution of the pollutant in the area. The results suggest that the threshold is frequently exceeded in the summer, and this may be very critical for the plants' health.File in questo prodotto:
