| Resumo: | Atmospheric pollution has become a key aspect for sustainable development world-wide. Lack of measurements of atmospheric nanoparticles properties at different geographic locations limits the understanding of the role atmospheric particulate matter plays in multiple biophysical and environmental processes and its corresponding risks for human beings. This study presents a method to measure atmospheric primary nanoparticle, secondary nanoparticle and microparticle data. Moreover, a process for samples characterization is proposed combining different spectroscopy techniques. ?The method allows researcher to collect, measure, store and characterize atmospheric nanoparticles properties including their electric charge. ?A specific sample characterization is proposed, based on different techniques such as TEM and RAMAN spectroscopy. ?The outcomes of the approach give science the chance to study new themes such as the importance of particulate matter charge in transmission of infectious respiratory diseases; the role of electric charge in pollutants deposition in the respiratory tract; the link between electric atmospheric charge of nanoparticles and meteorological variables. |
