“…For this study, average abundance of trace elements in crustal (soil) materials (Levinson, 1974) were used as background values (Table 2). The assessment criteria are generally based on the EF values, as proposed by Martinez-Martinez et al (2013). They had proposed five contamination categories from slight (<2) to excessive contamination (>16).…”

The objective of this study was to determine the concentration of trace elements in soils of Keana-Awe brine-fields. Composite soil samples were randomly collected at a depth of 0-15 cm and were analysed for molybdenum, zinc, arsenic, lead, cobalt, chromium, copper, barium and nickel using Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). Quantification of the degree of soil contamination by these trace elements was carried out using the enrichment factor (EF) and the geo-accumulation index (Igeo). The data were subjected to principal component analysis (PCA). The average concentrations were 1.56 ppm molybdenum, 1116.42 ppm zinc, 23.80 ppm arsenic, 71.40 ppm lead, 17.64 ppm cobalt, 237.35 ppm chromium, 24.16 ppm copper, 254.67 ppm barium and 143.71 ppm nickel. Cobalt, nickel and chromium showed positive loadings in component 1 with a total variance of 29.56%. Zinc, copper and lead showed positive loadings in component 2 with a total variance of 18.79%, while copper showed negative loading in component 3 with a total variance of 14.79%. Considering the concentration of trace elements in the soils and statistical analyses, we conclude that soils of the study area were severely enriched in molybdenum, cobalt, chromium, copper, barium, nickel, while arsenic and zinc are in excessive concentrations in the soils. These trace elements could have originated from geogenic and anthropogenic sources.

“…The factor 1.5 corrects for the fluctuations of a given metal in the environment as well as very small anthropogenic influences (Martinez-Martinez et al, 2013). This method categorised the metal pollution into seven classes (0 to >5), ranging from unpolluted to very highly polluted.…”

The soil sample obtained from shooting area contaminated with Pb, Cu, and Zn was investigated to determine the chemical forms of heavy metals with Tessier's sequential extraction method, which is constituted of five fractions such as 'exchangeable', 'bound to carbonate', 'bound to oxide', 'bound to organic matter', and residual fractions. The amount of organic matter was measured by loss on ignition (LOI) and then the results of 'bound to organic matter' and LOI were compared. The sequential extraction results show that 4.7%-45% of Pb, 6.2%-25.9% of Cu and 3.9%-15.3% of Zn belong to the 'bound to organic matter' fraction, but LOI result shows that only 1.0%-2.8% of organic matter exists in the soil sample. In heavy medium separation tests, because Pb and Cu extracted in 'bound to organic matter' and residual fractions were removed, the heavy metals in the fractions would exist as heavier forms. These results suggest that the part of heavy metal extracted in 'bound to organic matter' fraction would result from the oxidation of metallic forms by hydrogen peroxide and nitric acid used in the fraction, and, consequently, that the 'bound to organic matter' fraction should be investigated in detail to determine the removal method and treatment capacity when the Tessier's sequential extraction method is used to examine heavy metal contaminants resulted from elemental metal like bullets.

“…Accumulated mine tailings without proper management are major cause of soil heavy metal pollution in mining region (Ding et al 2011;García-Lorenzo et al 2014;Jordanova et al 2013). Numerous studies have been carried out on the negative impact of mine tailings on soil environment (Favas et al 2011;Li et al 2014b;Martínez-Pagán et al 2011;Rodriguez et al 2009;Wang and Mulligan 2009), while most of them were only focused on metal spatial distribution in mining soil (Liu et al 2010(Liu et al , 2013Martínez-Martínez et al 2013;Monterroso et al 2014) or leaching behavior of metal ions from mine tailings (Cukrowska et al 2004;García-Lorenzo et al 2014;Guo 2013;Kossoff et al 2011;Schwab et al 2007;Song et al 2015;Wang and Mulligan 2009). In fact, heavy metals that released from mine tailings are mostly associated with colloidal particles (Lower et al 2004;Pascaud et al 2015;Slowey et al 2007).…”

Exposed mine tailings could release substantial amounts of toxic metal-rich colloidal particles into soils during drying-wetting (D-W) cycles, but the mechanisms are still incompletely understood. In this study, two-layered (tailings above and soils below) packed columns were set to explore the effects of D-W cycles on tailing particle (TP) mobilization and transport in soil, and the mediating effect of TPs on the release and transport of heavy metals (Pb and Cu) was also examined. Results show that D-W cycles enhanced colloidal TP (approximately 190-712 nm) release from the column. The enhancing effect depends on duration of drying period, being slight for short-term drying (1, 3, 7, and 14 days) and significant for long-term drying (30, 60, and 90 days). The most interesting observation is the concentration valley of the effluent TPs during wetting event after 7-and 14-day drying. Based on these results, the dependence of TP mobilization and transport upon drying duration can be attributed to a combined action of different particle generation mechanisms during different drying periods, which appears to be relevant to the pore water content. The release and transport of Pb and Cu from the tailings into soil were dominantly mediated by the TPs and significantly enhanced by D-W cycles. These findings improve the understanding of TPs mobilization and transport in soil under fluctuating weather conditions.
