Effect of Industrial Effluent on the Growth Parameters of Eichhornia Crassipes, Vallisneria Spiralis and Lemna Minor

Abstract

The effect of organic and inorganic pollutants of effluent is expressed in tens of growth parameters like leaf number/plant, leaf area/plant, and chlorophyll content of the phytoremediators. it has been observed that with the increase in phytoremediation period, there is increase in leaf number and leaf area but a negative effect on chlorophyll a, chlorophyll b and total chlorophyll. The maximum change in growth parameters was observed when plants were grown in 20% concentration of the effluent followed by 40 % concentration of the effluent and pure water. Among three phytoremediators, E. crassipes exhibited more growth than Spiralis and L. minor.
