Platinum in indoor settled dust matter (homes and cars)

Abstract This paper presents a method for Pt analysis in indoor (homes and cars) settled dust, used as passive samplers, and the results relative to samples collected in the Sicilian area are used to evaluate the magnitude and distribution of concentrations inside common environments and the possible origins of the considered contaminant. The concentrations of platinum in settled indoor dust were measured by differential pulsed voltammetry (DPV). Concentrations of Pt in homes are in the range from 30 to 1460 μg kg − 1 d.w. while, in the vehicles from 30 to 1750 μg kg − 1 d.w. Considering the geoaccumulation index (I geo ), 42% of the settled dust sampled in homes could be classified as extr…
