Water contaminated with arsenic is a worldwide problem. This review presents the arsenic
contamination in groundwater, its sources, and possible health risk to humans. Groundwater …

Mine wastes pollute the environment with metals and metalloids in toxic concentrations,
causing problems for humans and wildlife. Microorganisms colonize and inhabit mine …

Refractory ores, in which gold is often embedded within As-bearing and acid-generating
sulfide minerals, are becoming the main gold source worldwide. These ores require an …

Passive treatment systems (PTSs) are effective for mine drainage (MD) treatment through
chemical and biological processes. The by-products of PTSs represent potential …

Pollutions associated with mining activities are environmentally challenging worldwide,
particularly in Sub Saharan African countries due to extreme climatic conditions, influencing …

Oxygen-induced abio-oxidation of Fe (II) and As (III) for Fe-As co-precipitation is proposed in
this work as a cost-saving and time-saving method to remove As from As-rich acid mine …

Passive treatment based on iron biological oxidation is a promising strategy for Arsenic (As)-
rich acid mine drainage (AMD) remediation. In the present study, we characterized by 16S …

Acid mine drainage (AMD) containing arsenic produced during coal mining is a global
environmental problem. However, the coupled driving process of the key element Fe and the …

Human activities are the main cause of arsenic contamination in the environment and water
resources, being the mining industry an important source of arsenic contamination because …

Natural attenuation in acid mine drainage (AMD) due to biological iron and arsenic oxidation
offers a promising strategy to treat As-rich AMD in passive bioreactors. A reactive transport …
