Phytoremediation Ability of Aquatic Fern (Azolla pinnata) in Lead and Zinc
Author(s): Shaik Umme Salma* and AT Ramachandra Naik
Heavy metals are environmental pollutants and their toxicity is a problem in increasing significance of ecological, evolutionary and nutritional reasons. They are ubiquitous in environment and higher concentrations poses serious threat to the aquatic ecosystem. The remediation of aquatic environment by aquatic plants known as phytoremediation is an emerging area of research. Hence, an effort was made to understand the role of aquatic fern Azolla pinnata in absorption and level of accumulation so as to understand the extent of phytoremediation value in aquatic environmental studies.
Accumulation profile of heavy metals in Azolla pinnata exposed to 25%, 50%, 75% and 100% dilutions of sewage and aquaculture effluents was carried out. Atomic absorption spectrophotometric analysis of sewage effluent accumulation in Azolla pinnata showed initial concentr.. View More»
