“…The actual AB for C10 was calculated to be 0.64% (average of 0.26 and 1.02%) and 6.28% (average of 2.98 and 9.58%) for C5, since the As 3+ concentration was about 50% for both samples (Table 5). The bioavailability of As relative to arsenate in the soil from disused mining areas has been reported as 11% 20 and 24% 14 in soil impacted by smelter activities; arsenic speciation was not determined in these studies. These bioavailability results were likely to be under-estimated if there were significant concentrations of arsenite in the soil samples.…”

Watson is a fully developed suburb of some 30 years in Canberra (the capital city of Australia). A plunge dip using arsenical pesticides for tick control was operated there between 1946 and 1960. Chemical investigations revealed that many soil samples obtained from the study area contained levels of arsenic exceeding the current health-based investigation levels of 100 mg kg 21 set by the National Health and Medical Research Council in Australia. For the speciation study, nine composite samples of surface and sub-surface soils and a composite sample of rocks were selected. ICP-MS analysis showed that arsenic levels in these samples ranged from 32 to 1597 mg kg 21 . Chemical speciation of arsenic showed that the arsenite (trivalent) components were 0.32-56% in the soil and 44.8% in the rock composite samples. Using a rat model, the absolute bioavailability of these contaminated soils relative to As 3+ or As 5+ ranged from 1.02 to 9.87% and 0.26 to 2.98%, respectively. An attempt was made to develop a suitable leachate test as an index of bioavailability. However, the results indicated that there was no significant correlation between the bioavailability and leachates using neutral pH water or 1 m HCl. Our results indicate that speciation is highly significant for the interpretation of bioavailability and risk assessment data; the bioavailable fractions of arsenic in soils from Watson are small and therefore the health impact upon the environment and humans due to this element is limited.

“…The gastrointestinal absorption efficiency for each trace element was based on the assumption that the bioavailability from dietary sources in the wild is reduced relative to dietary exposures in the laboratory because trace elements may be relatively tightly bound to protein, cellulose, or other cellular substances in the wild in comparison with the matrix effects for the soluble form of a trace element spiked into laboratory food or water. Absorption of trace elements associated with tailings, smelter emissions, or other particulate mining-related waste is limited by the incorporation of the trace element into mineral matrices ( e.g., Davis et al 1992).…”

“…The bioavailability of trace elements at mining sites is a key issue in both human and ecological risk assessments (Davis et al 1992;McKinney and Rogers 1992;Pascoe et al 1994). Trace elements such as As, Cu, Pb, and Zn may be enriched in soils, sediments, and surface waters as a result of mining-related activities (e.g., mine tailings, smelter emissions).…”

Pluvial deposition of tailings and other mining-related waste in selected riparian habitats of the Upper Clark Fork River Basin (Montana) have enriched trace elements in soils. The significance of trace element exposure to selected wildlife species was evaluated by measuring tissue residues of trace elements (As, Cd, Cu, Pb, Zn) in key dietary species, including dominant grasses (tufted hairgrass and redtop), willows, alfalfa, barley, invertebrates (grasshoppers, spiders, and beetles), and deer mice. Average trace element concentrations in grasses, invertebrates, and deer mice collected from tailings-affected sites were elevated relative to reference levels. Soil-tissue bioconcentration factors for grasses and invertebrates were generally lower than expected from the range of values in the literature, indicating the reduced bioavailability of trace elements from mining waste. In general, trace elements concentrations in willows, alfalfa, and barley were not elevated above reference levels. From these data and plausible assumptions for other exposure parameters for white-tailed deer, red fox, and American kestrel, trace element intake was estimated for soil and diet ingestion pathways. Comparisons of exposure estimates with toxicity reference values indicated that the elevated concentrations of trace elements in key food web species do not pose a significant risk to wildlife.
