Evaluating potentially toxic element accumulation in crops near abandoned mine tailings in northwestern Mexico: a One Health perspective.

ABSTRACT: This study investigated the accumulation of potentially toxic elements (PTEs) in crops cultivated near abandoned mine tailings (MTs) in San Felipe de Jesús, northwestern Mexico, with the aim of evaluating their compliance with food safety regulations. A total of 26 soil and crop samples were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). In soils, concentrations of lead (Pb), zinc (Zn), and cadmium (Cd) reached 367 mg kg⁻¹, 781 mg kg⁻¹, and 6.19 mg kg⁻¹, respectively, and declined exponentially with distance from the MTs, consistent with wind-driven dispersion. Soils exhibited moderate to poor resilience, with 34.6% classified as poor based on pH, organic carbon, cation exchange capacity, iron oxides, and calcium oxides. In crops, sev
