Environmental and health implications of Pb-bearing particles in settled urban dust from an arid city affected by Pb-Zn factory emissions.

ABSTRACT: Metal-rich particles originating from non-ferrous metallurgical activities are the primary source of atmospheric metals in urban environments. These particles vary in size, morphology, and elemental compositions and they undergo weathering processes that alter their composition and affect their toxicity. This study focuses on lead (Pb)-rich particles in settled urban dust within an arid and dusty city, Torreón in North Mexico, affected by Met-Mex Peñoles complex, one of the world's largest Ag-Cd-Pb-Zn smelting and refining facilities in operating since 1901. Torreón is characterized by arid conditions, temperature fluctuations, and low humidity. Dry atmospheric particles were collected in 2015 and 2017 from Torreón's urban area within a 3 km radius of the Met-Mex Peñoles complex. We used v
