“…Organic matter can form soluble complexes with As, increasing its mobility (Ko et al, 2004), and can increase Sb mobility in polluted areas when coupled with increasing pH (Nakamaru & Mart ın Peinado, 2017). In this regard, dissolved OM has been reported to complex Sb(V), with its strongest binding interaction occurring under neutral pH conditions (Fan et al, 2019).…”

Arsenic and antimony are metalloids that exhibit similar geochemical behavior and are often found in the same mineral associations, co-occurring in mine waste derived from ore exploitation. Due to their adverse effects on ecosystems and human health, techniques to limit their release into the environment from mine wastes and the consequent pollution of surrounding areas are of great interest. This review addresses the geochemical behavior of these two metalloids in mining environments and presents an overview of the main strategies used to stabilize or encapsulate As-or Sb-bearing mine waste, highlighting and comparing their shortcomings and advantages. Several approaches have been investigated, including the 1) establishment of surface covers, 2) application of amendments, 3) solidification using cementing or geopolymer, and 4) application of protecting coatings. Several of these methods have exhibited potential for treating As mine waste. However, the weathering state, composition, and final fate of wastes are determining factors affecting treatment effectiveness. Regarding Sb mine waste, only cementation processes have shown some good performance. Further research effort is required to develop effective passivating coatings or stabilization methods to treat these mine wastes.

“…Heavy metals, like other endocrine disruptors, can cause some damage to the endocrine system of aquatic organisms. One of the mechanisms of heavy metal exposure which leads to such metabolic diseases as hypertension and diabetes may be that heavy metals, organochlorine pesticides, and [6,40] polychlorinated biphenyls are known typical endocrine disruptors, which can interfere with hormone synthesis and secretion and form endocrine disruptive toxicity conditions. For example, the heavy metals Cd, Mn, and Cr may increase the incidence of metabolic disorders.…”

Water quality criteria are the scientific basis for formulating water quality standards and environmental management practices. Due to the development of urbanization and industrialization, the problem of heavy metal pollution has become a serious environmental problem. Heavy metals not only have major impacts on aquatic organisms, but also seriously threaten human health. However, the current environmental criteria refer to the maximum value limitations of environmental factors in environmental media where harmful or detrimental effects are not produced on specific protected objects. This study reviewed the sources, hazard levels, toxic effect mechanisms, and the current research status of China’s water quality criteria for heavy metal pollutants. In addition, the focus and direction of future research on the toxic effects of heavy metal on aquatic organisms and the necessary criteria changes were discussed. The present study would provide an important theoretical basis for the future research of water quality criteria and risk assessment of heavy metal pollutants.

“…It is thus of great significance to understand the oxidation and transformation of Sb and the interaction between microbes and the various forms of Sb under microbial mediation, as these reactions will enhance our understanding of Sb behavior in its biogeochemical cycle and environmental impacts ( He and Chen, 2014 ; Burton et al, 2019 ). These interactions are also fundamental in developing Sb pollution prevention and control ( Fan et al, 2019 ; Guo et al, 2019 ; He et al, 2019 ; Karimian et al, 2019a , b ) and bioremediation technology ( Shtangeeva et al, 2011 ; Long et al, 2019 ; Ma et al, 2019 ; Sun et al, 2019 ; Deng et al, 2020 ). Although the microbial metabolism of Sb has been preliminarily discussed in several studies ( Li et al, 2015 ; Liu et al, 2015 ), Sb(III) resistance mechanisms; Sb(III) oxidation characteristics and mechanisms; and the interaction between Sb-oxidizing bacteria and Sb are still poorly understood, and bioremediation technology for Sb pollution is difficult to apply in practice ( He and Chen, 2014 ; Burton et al, 2019 ).…”

A Critical Review of Resistance and Oxidation Mechanisms of Sb-Oxidizing Bacteria for the Bioremediation of Sb(III) Pollution

Antimony (Sb) is a priority pollutant in many countries and regions due to its chronic toxicity and potential carcinogenicity. Elevated concentrations of Sb in the environmental originating from mining and other anthropogenic sources are of particular global concern, so the prevention and control of the source of pollution and environment remediation are urgent. It is widely accepted that indigenous microbes play an important role in Sb speciation, mobility, bioavailability, and fate in the natural environment. Especially, antimony-oxidizing bacteria can promote the release of antimony from ore deposits to the wider environment. However, it can also oxidize the more toxic antimonite [Sb(III)] to the less-toxic antimonate [Sb(V)], which is considered as a potentially environmentally friendly and efficient remediation technology for Sb pollution. Therefore, understanding its biological oxidation mechanism has great practical significance to protect environment and human health. This paper reviews studies of the isolation, identification, diversity, Sb(III) resistance mechanisms, Sb(III) oxidation characteristics and mechanism and potential application of Sb-oxidizing bacteria. The aim is to provide a theoretical basis and reference for the diversity and metabolic mechanism of Sb-oxidizing bacteria, the prevention and control of Sb pollution sources, and the application of environment treatment for Sb pollution.
