Different concentrations of industrial effluents (0, 5, 10, 15, 20 and 100%) were
prepared with tap water. All physico-chemical parameters was observed in the differen
concentrations of the industrial effluents i-e pH, EC, TDS, COD, BOD, Cl, CO3, HCO3
The values of these parameters were increased with increasing the concentrations of th
waste water. Heavy metals were also analyzed in the different concentrations o
effluents and increasing trend was Cr >Cd >Pb. Eichhornia crassipes L. was grown in
these concentrations of the effluents for 15, 30 and 45 days of experiment. The growth
parameters like shoot length, root length, fresh weight of leaves, fresh weight of root
and leaves, dry weight of roots and leaves, was observed in the different concentration
of industrial effluents. The maximum growth was observed in the 10 and 15%
concentration and minimum growth was observed in 100% (industrial effluents). The
uptake of metals Cr, Cd, Pb was recorded after 15, 30 and 45 days of the experiment
The protein and chlorophyll content were also observed in the leaves of the Eichhornia
crassipes L. after 45 days of experiment. The aim of this study to observe the effect o
heavy metals on the protein, chlorophyll content and growth of Eichhornia crassipe
L. in different concentrations of industrial effluents of Shiekhupura.
