Lead Uptake and Growth Responses in Pistia Stratiotes Linn. (Quiapo)

Abstract

Pistia stratiotes was cultured in hydroponics solutions amended with three different lead (Ph) levels-2ppm, 4ppm, and 8ppm AAS analysis revealed that Ph accumulation in the plant tissue (BCF) increased with increasing Ph levels in the culture solutions, Ph accumulation had caused the development of chlorotic leaves and decreases in the fresh biomass of the plants. However, there was no interference of the Ph accumulation on the growth responses of Pistia in terms of moisture, chlorophyll, and protein contents. These findings imply that P. stratiotes might be useful in heavy metal decontamination process in industrial and domestic wastewaters. These responses also indicate the potential of Pistia as a lead scavenger and bioremediation tool in the aquatic environment.
