Heavy metal contamination and health risk assessment

2015-5-1  The present investigation was to appraise the degree of contamination and human risk assessment due to abandoned barite mine sites. The study has shown varying trends of contamination by different elements based on two methods, Contamination index and Nemerow pollution index, while human health risk assessment indicated the health risk through

Bioaccessibility of barium from barite contaminated soils

2015-10-23  Barite contamination of soil commonly occurs from either barite mining or explorative drilling operations. This work reported in vitro data for barite contaminated soils using the physiologically based extraction test (PBET) methodology. The existence of barite in plant tissue and the possibility of 'biomineralised' zones was also investigated

Safe Mining Assessment of Artisanal Barite Mining

Barite, used in mud formulation, is mined in several places to support the industry. However, there is insufficient literature on the downside of mining and associated hazards, especially in the artisanal barite mining sector. This paper contains three parts. The initial section reviews major causes of mining accidents and health hazards in Nigeria.

Bioavailability of barium to plants and invertebrates in

Contamination resulted from barite mining activities. Barium concentrations in contaminated soils determined by X-ray fluorescence were in the range 0.13-29.2%. Barite contaminated soils were shown to negatively impact both E. fetida and L. sativa relative to control soil. For E. fetida, pore-water concentrations and acid extractable Ba were

2019-11-15  Cadmium (Cd) is associated with barite; however, its biogeochemical characteristics in environments impacted by barium (Ba) mining are not known. Here, we first revealed the characteristics of Cd concentrations, distributions, and chemical forms in the soil-rice system in Ba mining areas.

2017-3-1  TENORM-contaminated soil was simulated by spiking a model soil, free of anthropogenic contamination, with γ-emitting 232 Th (ThO 2) at a concentration in soil of 2.0%.Based on our previous results (Falciglia et al., 2015), a 232 Th-concentration of 2.0% can be considered as a “worst-case” scenario.It was further shown that higher contamination levels can inhibit the hydration processes

2 Sources of Lead Contamination Investigative Strategies

Early mining and local mining focused on lead, but from the 1920s to the 1980s these residual deposits were mined by industrial methods for barite (MO DNR 2017; Mugel 2017). Page 16 Share Cite Suggested Citation: "2 Sources of Lead Contamination."

This resulted in many legal and illegal mining of barite, a major component used in the oil and gas indus-try in Nigeria. The mining and processing of barite generates vast quantities of mine rocks and mine tailings. Barite has been mined

Soil and/or groundwater contamination by arsenic, barium, cadmium, and lead at the Old Mines Site is most likely the result of lead and barite mining, milling, and smelting. Continuous lead mining began in Washington County in 1721 at the surface and near-surface (ten feet or less below ground surface (bgs)) in an area north of Potosi.
