Abstract

The results of an experimental analysis carried out to investigate PM2.5 concentration levels and the content of polycyclic aromatic hydrocarbons, as well as inorganic trace elements in the atmospheric particles are presented. Measurements were taken with a micrometeorological station equipped with an optical PM2.5 detector, and simultaneously, particles were collected on filters for subsequent chemical analyses. The average value of daily PM2.5 concentration is 21.5 ug/m 3 and real-time measurements indicate that the average concentration during the day (8 am to 8 pm) is about 25% lower than the nocturnal average. Short-time averages of PM2.5 decrease when the wind speed increases as consequence of the more efficient mixing. Meteorological measurements indicate the presence of a local daily (breeze) circulation with wind blowing from the Alps or the Adriatic Sea and, during this circulation, larger concentrations were observed, with wind coming from the Alps. Days of high PM2.5 concentration with dominant anthropic or with prevalent crustal contributions were identified. (literal)
