This paper aims to review the available studies that have been done concerning PM10and PM2.5concentrations in nurseries and primary schools since 2008, to provide a summary of the available scientific findings concerning the concentrations, indoor/outdoor (I/O) ratios and the sources. Levels of PM observed worldwide exceeded several times national legislations and WHO guidelines, especially in developing countries. I/O ratios were several times higher than 1 and high PM levels were reported as due mainly constant re-suspension of particles.
