Geochemical and isotopic characterization of lead in fugitive dust from unsurfaced roads in Missouri by Emitt C Witt( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

"Eighteen unsurfaced roadways in Missouri's rural Ozark region were sampled to characterize the differences in trace element and isotopic chemistry to determine if there is a human health concern with inhaling and/or ingestion of fugitive dust generated by a moving vehicle. Road reaches were selected to represent those in similar rural areas with and without the presence of mining activity--13 roads were selected in the Viburnum Trend (VT) resource mining area and five were located to the southwest of the mining areas. Samples were collected using a novel cyclonic fugitive dust sampler (patent pending) that collects a composite sample from a specific reach length of road surface directly from suspension. Preliminary results show that road dusts collected from the VT area have substantially larger concentrations of contaminant trace elements relative to those roads in non-mining areas with Pb being the predominant trace metal. Sequential extraction analysis of samples shows that Pb in the VT dusts is most often associated with the exchangeable + carbonate and reducible phases whereas road dusts outside the mining area had a larger proportion of the total concentration associated with the less mobile oxidizable and residual geochemical phases. In vitro simulated body fluid extractions revealed that as much as 78% and 100% of the total Pb concentration in mining road dusts is extracted by gastric and artificial lung fluids, respectively. Isotopic ratios of Pb from the individual sequential extracts for all dust samples show minimal difference indicating mixing among the operational phases; however, three component end-member mixing was useful in apportioning the total labile Pb among smelter deposition and/or fugitive road haulage, natural bedrock soils, and US aerosols"--Abstract, page iv
Isotopically constrained lead sources in fugitive dust from unsurfaced roads in the southeast Missouri mining district( )

Abstract: The isotopic composition of lead (Pb) in fugitive dust suspended by a vehicle from 13 unsurfaced roads in Missouri was measured to identify the source of Pb within an established long-term mining area. A three end-member model using 207 Pb/ 206 Pb and concentration as tracers resulted in fugitive dust samples plotting in the mixing field of well characterized heterogeneous end members. End members selected for this investigation include the 207 Pb/ 206 Pb for 1) a Pb-mixture representing mine tailings, 2) aerosol Pb-impacted soils within close proximity to the Buick secondary recycling smelter, and 3) an average of soils, rock cores and drill cuttings representing the background conditions. Aqua regia total concentrations and 207 Pb/ 206 Pb of mining area dust suggest that 35.4–84.3% of the source Pb in dust is associated with the mine tailings mixture, 9.1–52.7% is associated with the smelter mixture, and 0–21.6% is associated with background materials. Isotope ratios varied minimally within the operational phases of sequential extraction suggesting that mixing of all three Pb mixtures occurs throughout. Labile forms of Pb were attributed to all three end members. The extractable carbonate phase had as much as 96.6% of the total concentration associated with mine tailings, 51.8% associated with smelter deposition, and 34.2% with background. The next most labile geochemical phase (Fe+Mn Oxides) showed similar results with as much as 85.3% associated with mine tailings, 56.8% associated with smelter deposition, and 4.2% associated with the background soil. Graphical abstract: Highlights: End-member mixtures represent Pb-types from mine tailings, smelter deposition, and background soil/regolith. The three-component mixing model adequately constrains Pb-types in road dust samples. The largest source of Pb in road dust is from the Pb-mixture containing mine tailings. The smallest source of Pb in road dust is from the background component. Sequential extraction provides minimal additional resolution to Pb isotope forensic analysis. Abstract : Lead (Pb) in road dust is apportioned using a three end-member mixing model to mine tailings>smelter deposition>background with no improvement in using Pb isotopes to resolve source using any extraction solvent
