“…Several studies about the manufacture of handmade bricks show that pollutant gases are emitted such as SOx, NOx, CO, CO 2 , particulate matter (PM) or total suspended particulates (TSP)-particles that pass through a size-selective inlet with a 50% cut-off at 1, 2.5 and 10 µm aerodynamic diameter (PM 1 , PM 2.5 and PM 10 , respectively)-metals (Cu, Cr, Pb, Ni, Zn, Cd, Fe, Mn), fluorides and organic compounds (methane, ethane, volatile organic compounds (VOCs)), persistent organic compounds (POPs) and some hazardous air pollutants such as hydrogen chloride (HCl) and hydrogen cyanide (HCN) [64][65][66][67][68][69]. Akinshipe and Kornelius [69] reported that the contribution of brick production to global emissions of black carbon, organic carbon, PM 1 , SO 2 and CO is 5.5%, 2.6%, 1.6%, 2.9% and 1.6%, respectively.…”
