Abstract
A
rapid bioassay test was conducted to study heavy metal accumulation and
biochemical changes in Trigonella foenumgracum (methi) irrigated with
25, 50, 75 and 100% of effluent from flash light manufacturing industry at 60
days after sowing. Total metal concentration in effluent samples was:
Cr=0.12-1 whereas, metals
were not detected in control. An increase in photosynthetic pigments of
exposed plant was noticed up to 50% concentrations of the effluent followed
by a decrease at higher concentration as compared to their respective
control. An enhanced lipid peroxidation in the treated plants was observed,
which was evident by increased level of antioxidants: proline, cysteine,
malondialdehyde and ascorbic acid content. The treated plants accumulated
metals in the following order: Cu>Pb>Cr>Cd in the roots and shoots.
