Extensive mining activities increased the chromium (Cr) contamination in the environment. Cr, a potentially toxic metal arising from various natural and anthropogenic activities such as the electroplating, steel and leather industries, is carcinogen to living organisms as well as a risk to ecology. Hence, the remediation of Chromium pollution has gained widespread attention. The toxic nature of Cr severely affects plant growth and development. Naturally Cr exists in various oxidation states, including Cr(III) and Cr(VI). The hexavalent Cr is the most toxic and persistent form in soil. Plants uptake Cr through various transporters such as sulfate and phosphate transporters. In recent years, Cr accumulating plants has been recognized as one of the promising Phytoremediation methods for the Cr contaminated region. This review summarized the Phytoremediation techniques of Cr and uptake mechanisms of different plants.
