Heavy metals are significant environmental pollutants, and their toxicity is a problem of increasing significance of ecological, evolutionary, nutritional and environmental reasons. Water pollution is a global problem. The heavy metals are omnipresent in our environment, and higher concentration of heavy metals poses a serious threat to the aquatic ecosystem. The remediation of aquatic environment by aquatic plants i.e. phytoremedition is an emerging area of research. In the present investigation laboratory experiments were conducted to study the accumulation profile of heavy metals in Azolla filiculoides Lam., exposed to 25%, 50%, 75% and 100% concentration of sewage, at the interval of 4 days for 12 days. The results revealed that the accumulation of heavy metals in test plant varies with sewage concentration and duration of exposure and directly proportional to its concentration and duration of exposure. It is evident from the present investigation that the Azolla filiculoides Lam., can be used as phytotool for remediation of heavy metals from sewage. [ABSTRACT FROM AUTHOR] |
