“…For most of these, the Mo concentrations exceed those for uncontaminated soils (<10 mg/kg [5]) and upper continental crust (1.1 mg/kg, [26]). Exceptions include soils more than 250 m from the Portuguese Neves Corvo Cu-Pb-Zn mine [27], mine tailings and soils from the Portugues Ervedoa Sn-As mine [28] and rhizosphere soil around the Spanish Panasqueira Sn-W mine [29].…”

Abstract:Molybdenum is an essential element for life, with growing production due to a constantly expanding variety of industrial applications. The potentially harmful effects of Mo on the environment, and on human and ecosystem health, require knowledge of Mo behavior in mining-affected environments. Mo is usually present in trace amounts in ore deposits, but mining exploitation can lead to wastes with very high Mo concentrations (up to 4000 mg/kg Mo for tailings), as well as soil, sediments and water contamination in surrounding areas. In mine wastes, molybdenum is liberated from sulfide mineral oxidation and can be sorbed onto secondary Fe(III)-minerals surfaces (jarosite, schwertmannite, ferrihydrite) at moderately acidic waters, or taken up in secondary minerals such as powellite and wulfenite at neutral to alkaline pH. To date, no Mo-metabolising bacteria have been isolated from mine wastes. However, laboratory and in-situ experiments in other types of contaminated land have suggested that several Mo-reducing and -oxidising bacteria may be involved in the cycling of Mo in and from mine wastes, with good potential for bioremediation. Overall, a general lack of data is highlighted, emphasizing the need for further research on the contamination, geochemistry, bio-availability and microbial cycling of Mo in mining-affected environments to improve environmental management and remediation actions.

“…It is also used as a fireproof coating for other metals. Molybdenum compounds are applied as catalysts in the petroleum industry, and as dyes for the production of paints, inks, plastics and rubber products [Reimann andDe Caritat 1998, Smedley andKinniburgh 2017]. …”

“…Mo exists in several oxidation states; +4, +5 and +6 are the most important for environment [Smedley and Kinniburgh 2017]. Molybdenum easily forms complex anionic compounds that are mobile under neutral and alkaline conditions [Borovec 1993, Sjöstedt et al 2009].…”

Molybdenum is an essential element for humans, animals, and plants. But excess exposure to molybdenum substances may cause harmful effects. This chapter describes natural occurrence, production, uses, and chemical and biochemical properties of molybdenum substances, and possible adverse effects in relation to dose. The emphasis is on commercial inorganic molybdenum substances and those where the molybdate ion [MoO 4 ] 2− is the driver for a biological effect.
