Abstract:

Rapid growth of industrialization leads to pollution due to waste water. Many countries have experienced pollution hazards due to toxic metals. Industrial waste effluents containing toxic metals are creating water pollution problems. The present paper reports on the systematic studies of the uptake of Cr (VI) and the effect of the metal on some biochemical constituents of the plant Pistia stratiotes L. The biochemical parameters were : Hill activity, Chlorophylls, protein, free amino acid, inorganic phosphorus,   RNA, DNA, dry  weight and the activities  of Protease, RNase and Peroxidase, etc. The effects on the biochemical parameters differed from those in  control  experiments.  The absorption  of the  metal by the plants gradually  increased  with  increase  in  concentration  of  Cr  (VI)  in  the  culture medium. The aquatic plant species may be regarded as Cr (VI) accumulators. So, the plant Pistia stratiotes L. can serve the mankind as the scavenger of Cr (VI) from waste water.


Keywords: Toxic effect, Chromium (VI), Pistia plant, Removal from waste water
