AIR POLLUTANT EXPOSURE OF ADULT POPULATION IN MILAN (EXPOLIS STUDY)

摘要

In the framework of the EXPOLIS project a random Milan population sample of 250 subjects was selected for questionnaire applications ("diary sample"). An "exposure sample" (50 office workers) was selected for pollutant exposure evaluation. The results of the Milan study are compared with those of the other European centers participating to the project (Athens, Basel, Grenoble, Helsinki and Prague). The average time spent by the subjects in the different microenvironments varies little between the cities (95-97% of their time indoors, 2-4% in commuting and 1% outdoor). High PM2.5 workplace levels were found in Milan and Athens (58.6 and 60.1 μg/m~3). In all the cities TVOCs and benzene levels were higher in indoor environments and in personal exposure than outdoor concentrations. In all the cities the highest CO exposure were found during commuting (1.5-6.5 mg/m~3). The degree of perceived air pollution annoyance was higher during commuting than at workplace and home.
