Meharg et al. (2003) reported that husked rice grain, collected in several districts in Bangladesh with high arsenic levels in ground water, had arsenic concentrations ranging from 0.058 to 1.83 mg/kg, which indicated that, despite impact due to mining, crop cultivation in the country faces serious problems with arsenic-contaminated aquifers.Web

The mechanisms at different pH for the stabilization of arsenic (As) in mine tailings (MTs) using steelmaking slag were investigated using laboratory experiments. Two types of steelmaking slag were used in the experiments. Ca-slag has high pH and high calcium oxide content due to its short period of aging. In contrast, Fe-slag is oxidized for …Web

most often as arsenic sulfide or as metal arsenates and arsenides. Almost all of the arsenic used is obtained as a by-product of smelting of ores of copper, lead, cobalt and gold. Mining of these ores and the management of waste materials associated with mining operations is a significant source of arsenic released to the environment.Web

Abstract. Understanding the natural occurrence and the chemical and mineral forms of arsenic in the surface environment is of paramount importance in assessing the sources and pathways contributing to human exposure. Arsenic is a metalloid element, within Group Vb of the Periodic Table, but is often incorrectly referred to as a metal.Web

Arsenic belongs to the most toxic elements; therefore, its high concentrations in the environment are always a matter of special concern [1,2].Particularly, the strong enrichment of soils in As usually occurs in the sites associated with …Web
