Abstract:This study assessed PM2.5 concentrations and heavy metal composition in blacksmith workshops located in Mekarmaju village, Bandung Regency, Indonesia. The PM2.5 levels measured across seven workshops showed significantly elevated concentrations, ranging from 166.88 µg/m3 to 513.80 µg/m3, greatly exceeding the indoor air quality recommended by the World Health Organization (WHO). Chemical analysis revealed toxic heavy metals within PM2.5, including iron (Fe), chromium (Cr), nickel (Ni), manganese (Mn), zinc (Zn… Show more
