dc.description.abstract	Il monitoraggio della qualità dell’aria é un primo passo attraverso un futuro migliore perché ci segnala quale processo emette più sostanze dannose nell’atmosfera e dove c’è bisogno di applicare tecnologie nuove per ridurre le emissioni. In questo lavoro, la componente organica (IPA, TC-EC-OC, levoglucosano) e quella inorganica (metalli) sono state determinate mediante il monitoraggio attivo (filtri) e il biomonitoraggio (T. aeranthos).	it_IT
dc.description.abstract	In this study, the organic and inorganic fraction of the airborne particulate matter was determined on a) filter devices (active sampling), and b) by biomonitoring (passive sampling). Organic components of the atmospheric particulate such as PAH, compounds out of the carbonaceous fraction, and levoglucosan, which are demonstrated to induce adverse effects on humans’ health, were detected. Further, also inorganic compounds such as As and Hg were found in some exposed samples. Monitoring the components of the air is a first step towards an increase in life quality.	it_IT
