Phytoremediation competence of short-term crops on magnesite mine tailing

The soil pollution emerging from mining action is a major environmental concern, the finding of biological resolution for these disputes is substantial to reduce and recover metal harmfulness and spreading. Hence, this research was designed to appraise the phytoremediation capability of short-term cereal crops on magnesite mine tailing. Many sources reported that it took several months or a year for phytoremediation process. We provided for the first time the removal of metals from mine tailing in a shorter period at 56 days and obtained a huge percentage of removal results states that out of 14 crops, 7 crops such as J. curcas (47.2-72.3%), R. communis (41.7-67.1%), M. uniflorum (42.1-58.4%), O. sativa (35.6-61.5%), V. ungiculata (39.3-67.5%), P. glaucum (37.3-58.9%), and G. hirsutum (45.5-68.2%) removed in the range of 35.6-72.3% from the tailing of magnesite mine. Besides that, this results also alarming us the possibilities of entering these metals into the human and animals through consumption of foods derived from these types of crops cultivated from metal polluted soil.

Automated summary

This research investigates the phytoremediation capability of short-term cereal crops on mine tailings, showing that some crops can remove metals from tailings within 56 days. The results also raise concerns about the possibility of metals entering human and animal bodies through consumption of crops cultivated in metal-polluted soil.
