The increased use of chromium (Cr) in several anthropogenic activities has led to the subsequent soil, surface water and ground water contamination. It has wide applications in the dyes, stainless steel, leather tanning, electroplating of chrome, and wood preservatives industries. Chromium exists in the environment in several diverse forms such as Cr(0), Cr(III) and Cr(VI) species. Cr toxicity depends on its valence state. Cr(VI) which is regarded as being highly mobile is toxic, while Cr(III… Expand

Chromium and the Plant: A Dangerous Affair?
Abstract Contamination of aquatic and terrestrial environments by toxic chromium (Cr) species is a worldwide increasing problem. Cr occurs in the environment mainly as Cr(III) and Cr(VI) species. CrExpand
Chromium biogeochemical behaviour in soil-plant systems and remediation strategies: A critical review.
TLDR
There is a plausible link among Cr sources, levels, chemical forms, and phytoavailability in soil; Cr accumulation and translocation in plants; and Cr phytotoxicity and detoxification in plants as well as the environmental impacts resulting from the application of reductive materials. Expand
A critical review on bioremediation technologies for Cr(VI)-contaminated soils and wastewater
Abstract Chromium (Cr) is a potentially toxic metal originating from natural processes and anthropogenic activities such as the iron-steel, electroplating, and leather industries, which is carcinogenExpand

Microbial Cd(II) and Cr(VI) resistance mechanisms and application in bioremediation.
TLDR
This review focuses on the highlighting of novel achievements on microbial Cd(II) and Cr(VI) resistance mechanisms and their bioremediation applications and the knowledge gaps and research perspectives are discussed in order to build a bridge between the theoretical breakthrough and the resolution of Cd-II and Cr-VI contamination problems.

Chromium speciation, bioavailability, uptake, toxicity and detoxification in soil-plant system: A review.
TLDR
There is a dire need to monitor biogeochemical behavior of Cr in soil-plant system, as Chromium induces phytotoxicity by interfering plant growth, nutrient uptake and photosynthesis, inducing enhanced generation of reactive oxygen species, causing lipid peroxidation and altering the antioxidant activities. Expand
Speciation, toxicity, microbial remediation and phytoremediation of soil chromium contamination
Contamination of soil by toxic chromium (Cr) is a rising health issue due to over-exploitation and industrial production. Toxicity can be decreased by bioremediation because some microorganisms areExpand
Conductive polymer-based nanocomposites for the removal of hexavalent chromium and trivalent arsenic from wastewater solution
Abstract Wastewater is spent or used water that has been discharged from industrial, domestic, and agricultural activities and contains contaminants such as bacteria, heavy metals, and fungi. UnlikeExpand
Simultaneous Speciation Analysis of Arsenic, Chromium, and Selenium in the Bioaccessible Fraction for Realistic Risk Assessment of Food Safety.
TLDR
The simultaneous speciation analysis of As, Cr, and Se revealed that the simple act of cooking can convert all of the carcinogenic Cr(VI) to the safer Cr(III). Expand
