Chromium Stress in Plants: Toxicity, Tolerance and Phytoremediation (2021, background): “Cr emitted into the air through sources such as Cr-based automotive catalytic convertors, tobacco smoke, and coal combustion also end up in soils [9].”
Glycinebetaine mediates chromium tolerance in mung bean through lowering of Cr uptake and improved antioxidant system (2016, background): “Chromium (Cr) accumulation in agricultural soils has become a global scientific concern due to its non-biodegradability and adverse effects on plant growth and productivity (Nagajyoti et al. 2010; Singh et al. 2013; Dheeba et al. 2015).”
Heavy Metal Stress and Some Mechanisms of Plant Defense Response (2015, background): “Cr is transported and accumulated via carrier ions such as sulfate or iron and is not directly absorbed by plants [32, 33].”
Chromium immobilization by extraradical mycelium of arbuscular mycorrhiza contributes to plant chromium tolerance (2016, background): “Naturally Cr has two stable forms, hexavalent chromium [Cr(VI)] and trivalent chromium [Cr(III)], of which Cr(VI) is highly mobile, and more toxic than Cr(III) for its mutagenic and carcinogenic effects (Losi et al., 1994; Singh et al., 2013a).”
Metal bioavailability and toxicity in freshwaters (2015, background): “For example, hexavalent chromium is usually associated with oxygen, producing oxyacids like chromate ions (CrO4 ) or dichromate (Cr2O7 ) (Singh et al. 2013).”
