Atmospheric emissions of Fe-containing nanoparticles from industrial activities.
Air inhalation of exogenous Fe-containing nanoparticles (NPs) can lead to their occurrence in human organs. Comprehensive recognition on unintentional releases of Fe-containing NPs from ongoing large industrial activities is urgently required for sustainable human health. Here, we quantified Fe-containing NPs emissions in fine particulate matter collected from 132 full-scale industrial plants belong to 13 industrial categories. For the 13 investigated industries, most particles had a diameter of <80 nm. The sources with the highest Fe-containing NPs concentrations were hazardous waste incineration (1.4 × 1012 particles/g), followed by blast furnace production of pig iron (6.2 × 1011 particles/g) and electric-arc furnace steelmaking (4.7 × 1011 particles/g). The annual total atmospheric emission of Fe-containing NPs from the 13 industries in China was 1.03 × 1024 particles. Emissions of Fe-containing NPs from the 13 industries contribute to elevated concentrations of these particles in the atmosphere surrounding factories, potentially posing health risks to the general population. Coal-fired power plants, cement kiln co-processing of solid waste, blast furnace production of pig iron, coking plants, iron-ore sintering, electric-arc furnace steelmaking, and hazardous waste incineration collectively contributed to 99.9 % of the total annual atmospheric emissions from the 13 industries. These results are important for evaluating emissions and enhancing the sustainability of global industrial development.
期刊介绍:
The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere.
The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
