CCSEM-based single-particle analysis identified ten pollution source types in Benxi, a typical steel city. Soil dust (31.5%) and construction dust (17.4%) were the dominant local sources, with significant seasonal and spatial variations. The graphical abstract image was generated using Adobe Firefly.
