Resumo
Atmospheric nanoparticles are presented in atmosphere, both by primary and secondary formation processes, and they can affect human health and climate change. Secondary formation processes encompass both new particle formation and growth events, among other processes. The study of levels and evolution of atmospheric nanoparticles was carried out at the University Institute of Research in Environmental Studies of University of A Coruna, a suburban area during 2013. The Scanning Mobility Particle Sizer (SMPS) was used to measure the submicron particles, and meteorological parameters were also measured. The influence of sea breeze to take place nucleation events had studied and this demonstrated that nucleation mode was presented by new particle formation process with the presence of sea breeze and at midday hours and by direct emissions, like road traffic, during the rest hours, regardless the origin of air masses. Also, during 2013 lower nanoparticle concentrations were measure than during 2012 and 2011 and the three years presented one maximum in Aitken mode but 2012 had other maximum in nucleation mode too.
