“…However, little information is known about the mechanism of bonding these metals to the soil and also the mechanism of releasing these metals from the soil [1]. Metal concentration and bioavailability vary according to the time and environment and depends on the variation of the soil properties like the composition, the reduction/oxidation reaction, adsorption/desorption and on the chemical properties of the received metals [2].…”

“…These heavy metals have an excellent potential to transfer to the ecological system and the food chain [1,2]. Different methods have been used for the remediation of metals from soils like extraction with chelating agents (EDTA or other biodegradable agents) [3], sequential acid leaching [4], washing [5], hydrometallurgy technique [6], Bioelectrochemistry [7] and phytoremediation [8].…”

The potentional of plants to cleanup metals from an old landfill site

2017

Old landfill sites contain different hazardous materials like heavy metals which have the ability to affects the entire environment. These places are sometimes covered by plants to increase the stability of the soil and to reduce the effects of erosion. 15 soil samples (3 samples from each place) and 5-7 timothy-grass (Phleum pretense) plants from 5 different places were taken from an old landfill place in an active landfill site in Högbytorp /Sweden owned by Ragn-sells Group Company. XRF scanning was used to analyze the metal content of soil samples and of plants. High concentrations of metals were detected in the soil samples like Fe with an average of about 25000 ppm, Mn about 250 ppm and 2800 ppm of Ti. The plants results showed an average concentration of Fe in the shoots about 730 ppm, Mn about 60 ppm and Ti about 1760 ppm. On the other hand, the roots results showed an average concentration of about 10 000 ppm of Fe, about 160 ppm of Mn and 2200 ppm of Ti. These results gave the indication that the Timothygrass has the ability to extract metals from contaminated soils and can help to cleanup these soils.

“…Although the industrial and agricultural sectors are largely responsible for environmental degradation and toxic metal pollution, some contamination comes from natural geological sources, and these can be evaluated through geochemical factor analysis [1][2][3]. Mercury is a highly toxic element, and is released into the environment as metallic Hg [4,5].…”

“…Bioaccumulation of metals in the food chain process occurs in all animals, including food animals such as fish and cattle, and also in humans [2,14]. Diet in large mammals is the main route for metal accumulation, causing heavy metal accumulation in the kidneys, liver, bones, hair, and blood of these mammals.…”

Mercury Contamination of Cattle in Artisanal and Small-Scale Gold Mining in Bombana, Southeast Sulawesi, Indonesia

et al. 2017

Abstract:The industrial mining sector is one of the main contributors to environmental damage and toxic metal pollution, although some contamination originates from natural geological sources. Due to their position at the top of the food chain, cattle tend to bioaccumulate mercury (Hg) in their bodies. We used analyses of cattle hair samples to investigate Hg contamination in cattle farmed within and outside of an artisanal and small-scale gold-mining area in Bombana, Southeast Sulawesi, Indonesia. We also examined the factors that might have influenced the toxicity, such as the environmental conditions, sex, and age of the cattle. A total of 63 hair samples were analyzed by particle-induced X-ray emission spectrometry. The mean Hg concentration was significantly higher in hair from cattle farmed within the artisanal and small-scale gold mining area (11.44 µg/g hair) than in those farmed outside the area (2.89 µg/g hair, p < 0.05). A possible cause of this is contamination by mercury persistent in terrestrial food chain. The results indicates that the level of toxic metals such as Hg need to be controlled in food sources to protect human health, especially in Bombana, Indonesia.

“…Enrichment factors in the upper section of the soils profiles are comparable to those of the studied peat mires for Cd and Ag, however Mo and Sb values are lower reflecting their lower relative sensitivity to enrichment (Table 4.4) and implying they are being diluted by additions of natural sediment. Previous studies have demonstrated that, even in areas proximal to emission sources, the identification of industrial metals in soils may be complicated by high background concentrations, or by natural variability within the soil profile (Barbieri et al, 2014).…”

The fate of atmospheric metal pollutants in the landscape, Snowy Mountains, south-eastern Australia

Industrial metals, emitted to the atmosphere by human activity, have been transported and deposited to almost every location on Earth, including Antarctica and Greenland. This is demonstrated by an increasing body of literature in which many atmospheric industrial metals (e.g. Pb, Hg, Cd and Cu) have been shown to be significantly enriched in environmental archives. Studies have largely focussed on peat mires and ice cores, which receive high rates of atmospheric deposition relative to terrestrial inputs. By contrast, few studies have examined the extent of atmospherically derived metals across the wider landscape, where processes such as pedogenesis, erosion and sedimentation affect the spatial extent and magnitude of metal enrichment. In the Snowy Mountains, Australia, atmospheric pollutant metals have previously been identified in alpine peat mires, although their impact on the wider environment has not been assessed. Interest in the fate of atmospheric pollutants in the Snowy Mountains has increased due to the operation of a cloud seeding program in which, silver iodide, AgI, is released to the atmosphere, leading to concerns that silver, Ag, contamination may be accumulating in this ecologically important region. This thesis examines the spatial extent and magnitude of atmospherically derived metals in the SnowyMountains by investigating patterns of enrichment in a range of geomorphic settings and catchment positions, including in soils, peat mires, lakes and reservoirs. The potential movement of metals through the landscape was also assessed by examining rates of geomorphic processes, including rates of pedogenesis and erosion, determined via radionuclides. The thesis was undertaken in three parts which are summarised below. by atmospheric deposition (ombrotrophic peat mires in the upper parts of catchments), the order and magnitude of metal enrichment most closely resembled that of collected aerosols, however, on average enrichment was 5-7 fold lower than in the aerosols. Metals most sensitive to enrichment, i.e., those with low natural abundance in local sediments (Cd, Ag, Sb, Mo), were enriched in all environments including the most geomorphically active settings (tarn lake sediments). In reservoirs, located lower in catchments, patterns of metal enrichment largely reflected concentrations in catchment soils but metals were additionally enriched or depleted depending on their relative particle reactivity. For those metals which are most sensitive to enrichment (Ag, Cd, Sb), the increase in excess flux required to reach trigger value concentrations is lowest in the reservoir sediments (Ag: 13-18, Cd: 7-10 and Sb: 17-61 times the current flux) and highest in the tarn lake (Ag: 60, Cd: 15, Sb: 27 times the current flux) and the peat mire (Ag: 74, Cd: 15, Sb: 18 times the current flux).In part three of this thesis, rates of soil production and soil erosion were quantified using radiocarbon dating, fallout radionuclides and sediment yields in lakes and reservoirs in order to assess the stability of l...
