Metal(loid) bioaccessibility of atmospheric particulate matter from mine tailings at Zimapan, Mexico.

ABSTRACT: Metal(loid)s are contaminants of concern emitted as particulate matter (PM) from several pollution sources. The objective was to characterize potential exposure from local airborne metal(loid)s in a community in proximity to mine tailings. Air samples were collected weekly at five sites around the municipal mine tailings using two Hi-volume samplers for simultaneously collecting PM₁₀ and PM_2.5. Total suspended particulates (TSP), concentrations, speciation, and bioaccessibility of metal(loid)s were quantified. The size and form of particles were determined by scanning electron microscopy. The concentration of TSP (μg m^-3) in the airborne samples ranged from 21.2 to 64.6 for PM_2.5 and 23.6 to 80.1 for PM₁₀. The profiles of analyzed quas
