ABSTRACT
Although industrial activities are significant contributors to atmospheric releases of particulate matter (PM) and associated toxic substances that lead to adverse human health effects, a knowledge gap exists concerning the human health risk resulting from such activities owing to lack of evaluation of industrial emissions. Here, we comprehensively characterized and quantified PM from 118 full-scale industrial plants. The dominant (97.9â¯%) PM showed diameters of <2.5⯵m; 79.0â¯% had diameters below 1⯵m. Annual atmospheric releases of Fe and heavy metals (As, Cd, Cr, Cu, Ni, Pb, Zn) contained in fine PM from these global industrial activities are estimated to be 51,161â¯t and 69,591â¯t, respectively. Emissions of heavy metals from these industries cause increased cancer risk, estimated to range from 1461â¯% to 50,752â¯%. Five crystalline compounds (ZnO, PbSO4, Mn3O4, Fe3O4, Fe2O3) that can indicate specific industrial sources are identified. Global annual emissions of these toxic compounds in fine PM from the industrial sources are estimated to be 78,635â¯t. The Global South displayed higher emissions than the Global North. These results are significant for recognizing regional health risks of industrial emissions.
