Analisi della concentrazione di PM10 in zona ad alto rischio industriale

The aim of this analysis is to study the relationships between some meteorological variables and a micro-pollutant, the PM10, which has a remarkable impact on environment and health. PM10 is a particulate (powders) whose diameter is less than 10 microns. In Italy, the quantity of this pollutant in the air has been recently controlled according to D.M. n.60 of 2nd April 2002. The study has been carried out analysing the two-year data (2000-2001) provided by three stations belonging to the CIPA monitoring net, located in the industrial area of Priolo-Melilli, in the province of Syracuse, Italy. The data show a remarkable variability of PM10 concentration during the different seasons. This fact can be related for sure to the influence of the meteorological variables which condition the movement and dispersion of the pollutant. In the present study, by the use of statistical instruments, we verify the inter-relationships between PM10 concentration and the main meteorological parameters, i.e. temperature, humidity, speed and direction of the wind. The results obtained suggest an important correlation between PM10 concentration and the meteorological variables considered; it thus provides not only precise information on the air quality of the area monitored but even the possibility to make short-term predictions regarding the concentration of the pollutant.
