The main objective of the study was to study the impact red mud waste extract on a crop plant. The red mud waste extract (RMWE) prepared in the laboratory is equivalent to the extract chemicals leaking from the red mud pond. The DNA, RNA, protein and FAA content significantly decreased in lechate exposed green gram seedlings in petriplate culture compared to control values indicating significant inhibition. Little insignificant increment in FAA and RNA in lechate exposed seedlings did not indicate any impact except the fact that increases in FAA in exposed seedlings might be a case of proteolysis in the exposed seedlings. Significant decrease in the DNA, RNA, protein and FAA content in lechate exposed green gram seedlings in pot culture compared to control values were noted. These biomolecular depletion no doubt indicate significant inhibition caused by the toxicant (RMWE). Little insignificant increment in FAA and RNA in lechate exposed seedlings did not indicate any impact except the fact that increases in FAA in exposed seedlings might be a case of proteolysis in the exposed seedlings as stated earlier. Significant decrease in DNA content and depletion in protein content was probably due to cell death and proteolysis caused by the toxicant. The leaf and root showed accumulation of alumina and maximum deposition was noted in the roots compared to leaf. No residual alumina accumulation was observed in the seeds of green gram plants after prolonged exposure to lechate waste, hence this crop can be recommended for cultivation in the contaminated site instead of rice cultivation.
