Abstract PM 2.5 ‐bound antimony (Sb) may threaten human health and sustainable development, necessitating accurate source identification for its effective control. This study pioneered the application of Sb isotope signatures to trace sources, presenting first isotopic fingerprints in urban . We selected two mega‐cities with contrasting profiles: more developed Wuhan central less Guiyang southwest China. Urban both cities exhibited an ε 123 value 1.84 ± 0.79‱, a distinct seasonal pattern, that is, heavier isotopes spring/winter lighter summer/autumn. Isotopic apportionment revealed waste incineration as predominant anthropogenic cites at 34.0–39.1%, despite their massive economic industrial differences. Brake wear emerged second major source, especially Wuhan, where vehicle ownership is greater, accounting 21.2%. Complementary analyses using enrichment factor, elemental ratios, positive matrix factorization modeling, backward trajectory analysis corroborated findings. offers novel approach identify unveiling brake contributors from new perspective.
