The concentration of potentially toxic elements (zinc, iron, manganese) bound PM2.5 in the indoor air of urban schools: a global systematic review and meta-analysis
In this study, the concentration of Zn, Fe, and Mn in the indoor air of schools bound PM2.5 were meta-analyzed. PubMed and Scopus were used to retrieve papers related to the concentration of PTEs bound PM2.5 in the indoor air of urban schools from January 1, 2000 to March 10, 2020. The concentration of PTEs in PM2.5 was meta-analyzed based on the country subgroup in the random-effects model (REM). Thirty papers with 25 data reports were included in the study. The rank order of PTEs bound PM2.5 was Zn (17.32  ng/m3)  >  Fe (14.49 ng/m3)  >  Mn (7.40 ng/m3). The rank order of countries based on the concentra...
