“…The Cu content found in the study exceeded the levels reported by Ning et al (2011). Ning et al (2011), as well as Cobbina et al (2015), reported heavy metals other than Cu (Table 2), which might have occurred because of different production processes in the gold mining industry.…”

The objective of this study was to evaluate the characteristics of mangium bark and its biosorbent ability to reduce heavy metal ions in standard solutions and wastewater and to assess changes in bark characteristics after heavy metal absorption. The experiments were conducted to determine heavy metal absorption from solutions of heavy metals alone and in mixtures as well as from wastewater. The results show that mangium bark can absorb heavy metals. Absorption percentages and capacities from single heavy metal solutions showed that Cu(2+) > Ni(2+) > Pb(2+) > Hg(2+), while those from mixture solutions showed that Hg(2+) > Cu(2+) > Pb(2+) > Ni(2+). Wastewater from gold mining only contained Cu, with an absorption percentage and capacity of 42.87 % and 0.75 mg/g, respectively. The highest absorption percentage and capacity of 92.77 % and 5.18 mg/g, respectively, were found for Hg(2+) in a mixture solution and Cu(2+) in single-metal solution. The Cu(2+) absorption process in a single-metal solution changed the biosorbent characteristics of the mangium bark, yielding a decreased crystalline fraction; changed transmittance on hydroxyl, carboxyl, and carbonyl groups; and increased the presence of Cu. In conclusion, mangium bark biosorbent can reduce hazardous heavy metal ions in both standard solutions and wastewater.

“…In artisanal and small-scale mining, it is a common practice for waste material to be removed and piled in large mounds at the mining site. These piles of tailings often contain heavy metals found in the ore and in many instances also contain mercury waste that was used during the amalgamation of gold (Cobbina et al, 2015). In such instances, these tailings are exposed to the elements and can be easily weathered, releasing toxic metals into the soil, adjacent water bodies and ultimately groundwater.…”

Ground water is the source of drinking water for many people around the world, especially in rural areas. A lot of parameters such as the concentrations of Arsenic, Copper, Zinc and other heavy metals in conjunction with other physico-chemical properties contribute to the suitability of water for drinking and for other purposes. This study was carried out in the Bibiani-Anhwiaso-Bekwai District of the Western region of Ghana to assess the presence and the levels of selected heavy metals (As, Cu, Zn) pollution of boreholes from different villages in the study areas using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The result of the study revealed that, the mean concentrations of As, Cu and Zn in the analyzed samples were 0.00143, 0.0186 and 0.0329 mg/L, respectively. The analysis of variance showed that there were significant differences in the Arsenic concentrations among the eight boreholes (F=4.078, P=0.033). However, the differences in the concentrations of Copper (F=1.592, P=0.264) and Zinc (F=0.741, P=0.647) from the eight boreholes were not significant. Concentrations of the selected heavy metals in analysed water samples were below the acceptable limits of World Health Organization (WHO) and Ghana Environmental Protection Agency (GEPA). The concentration of the selected heavy metals may be attributed to the activities of panners, improper disposal of sewage and solid materials containing toxic chemicals and the indiscriminate use of farming inputs such as fertilizers and pesticides which have impacted on the water quality of the selected boreholes in the study areas. Although the levels of the selected heavy metals in these water samples did not exceed WHO and GEPA permissible limits, it is necessary for residents in the study areas to be provided with potable water.

Abstract. The solution mining of salt mineral resources may contaminate groundwater and lead to water inrush out of the ground due to brine leakage. Through the example of a serious groundwater inrush hazard in a large saltmining area in Tongbai County, China, this study mainly aims to analyse the source and channel of the inrushing water. The mining area has three different types of ore beds including trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, with the formula Na 2 CO 3 × NaHCO 3 × 2H 2 O, it is a non-marine evaporite mineral), glauber (sodium sulfate, it is the inorganic compound with the formula Na 2 SO 4 as well as several related hydrates) and gypsum (a soft sulfate mineral composed of calcium sulfate dihydrate, with chemical formula CaSO 4 × 2H 2 O). Based on characterisation of the geological and hydrogeological conditions, the hydrochemical data of the groundwater at different points and depths were used to analyse the pollution source and the pollutant component from single or mixed brine by using physical-chemical reaction principle analysis and hydrogeochemical simulation method. Finally, a possible brine leakage connecting the channel to the ground was discussed from both the geological and artificial perspectives. The results reveal that the brine from the trona mine is the major pollution source; there is a NW-SE fissure zone controlled by the geological structure that provides the main channels through which brine can flow into the aquifer around the water inrush regions, with a large number of waste gypsum exploration boreholes channelling the polluted groundwater inrush out of the ground. This research can be a valuable reference for avoiding and assessing groundwater inrush hazards in similar rock-salt-mining areas, which is advantageous for both groundwater quality protection and public health.
