Advances in Nutrition, 2018 Two oxidation states of chromium are considered to be biologically and environmentally relevant based on their stability in the presence of water and oxygen. Compounds containing chromium(6 + ) are mutagenic and carcinogenic when inhaled and potentially when ingested orally in large quantity as well.

Health hazards of hexavalent chromium (Cr (VI)) and its microbial reduction
Bioengineered, 2022 Industrial effluents/wastewater are the main sources of hexavalent chromium (Cr (VI)) pollutants in the environment. Cr (VI) pollution has become one of the world’s most serious environmental concerns due to its long persistence in the environment and ...

Chromium toxicity, speciation, and remediation strategies in soil-plant interface: A critical review
Frontiers in Plant Science, 2023 In recent decades, environmental pollution with chromium (Cr) has gained significant attention. Although chromium (Cr) can exist in a variety of different oxidation states and is a polyvalent element, only trivalent chromium [Cr(III)] and hexavalent ...

Effects of Cr doping on the magnetic properties of one-dimensional spin chain system α–CoV2O6
AIP Advances, 2023 This study investigates the structural and magnetic properties of α–CoV2O6 and Cr doped α–CoV2O6 samples synthesized using a wet chemical method. X-ray diffraction (XRD) measurements and analysis indicate that α–CoV2O6 forms in a monoclinic crystal ...

Seebeck coefficient of Cr100−zOsz alloy system
AIP Advances, 2022 The magnetic phase diagram of the Cr100−zOsz alloy system exhibits possible quantum critical behavior (QCB), with commensurate spin-density-wave to paramagnetic (CSDW-PM) phase line terminating at z ≈ 14, in a superconducting dome at z ≈ 12.

Neutron diffraction study of the Cr84.7Re15.3 alloy
AIP Advances, 2021 Measurements of the temperature dependence of electrical resistance (R) and neutron powder diffraction (NPD) of a Cr84.7Re15.3 alloy is reported. The magnetism originates from the formation of a spin-density-wave (SDW) as a result of nesting between the ...
