Phytoremediation of hexavalent chromium by mung bean through bio-accumulation and bio-stabilization in a short duration

Phytoremediation is an effective approach to remove the challenging pollutant of hexavalent chromium [Cr(VI)] in the environment, however, which requires a relatively long work duration. Herein, we reported the utilization of mung bean (Vigna radiata) as a highly efficient accumulator for Cr(VI). Typically, within a short work duration of only 7 days, 5041 mg center dot kg(-1) of chromium (Cr) could be accumulated in the whole plants of mung bean. Moreover, about 80% of Cr in the mung bean plants are transformed to fractions with low bioavailability. This study demonstrated that mung bean could be a promising candidate for phytoremediation of Cr(VI), not only accumulating but also stabilizing Cr(VI) within very short time.

Automated summary

Mung bean is an efficient accumulator of Cr(VI), capable of accumulating a significant amount of chromium within a short period of time. This study demonstrated that around 80% of the accumulated chromium in mung bean plants is transformed into fractions with low bioavailability, making mung bean a promising candidate for phytoremediation of Cr(VI) due to its ability to rapidly accumulate and stabilize the pollutant.
