Geochemical sources, forms and phases of soil contamination in an industrial city

Popis výsledku v původním jazyce

This study examines current soil contamination in an Australian industrial city, Newcastle. Public (roadside verges and parks) and private (homes) surface soils (n = 170) contained metal(loid)s elevated above their respective Australian Health Investigation Levels (HIL). Lead (Pb), the most common contaminant in the city, exceeds the HIL for residential soils (HIL-A, 300 mg/kg) in 88% of private soils (median: 1140 mg/kg). In-vitro Pb bio-accessibility analysis of selected soils (n = 11) using simulated gastric fluid showed a high affinity for Pb solubilisation (maximum Pb concentration: 5190 mg/kg, equating to 45% Pb bio-accessibility). Highly soluble Pb-laden Fe- and Mn-oxides likely contribute to the bio-accessibility of the Pb. Public and private space surface soils contain substantially less radiogenic Pb (range: Pb-208/Pb-207: 2.345-2.411, Pb-206/Pb-207: 1.068-1.312) than local background soil (Pb-208/Pb-207: 2.489, Pb-206/Pb-207: 1.198), indicating anthropogenic contamination from the less radiogenic Broken Hill type Pb ores (Pb-208/Pb-207: 2.319, Pb-206/Pb-207: 1.044). Source apportionment using Pb isotopic ratio quantification and soil mineralogy indicate the city&apos;s historic copper and steel industries contributed the majority of the soil contaminants through atmospheric deposition and use of slag waste as fill material. High-temperature silicates and oxides combined with rounded particles in the soil are characteristic of smelter dust emissions. Additionally, a preliminary investigation of polycyclic aromatic hydrocarbons in soils, sometimes associated with ferrous metal smelting, coal processing or burning Of fossil fuels, shows that these too pose a health exposure risk (calculated in comparison to benzo(a)pyrene: n = 12, max: 13.5 mg/kg, HIL: 3 mg/kg).
