Title:

11.PHYTOVOLATILIZATION POTENTIAL OF Bacopa monnieri (L.) Pennell :-A PHYTOREMEDIANT FOR ENVIRONMENTAL ASSESSMENT

Authors :

Hussain. K

Abstract :

Plants in general and aquatic plants in particular absorb and accumulate minerals and metals from soil/aquatic environment. Bacopa monnieri is highly medicinal, a creeping emergent herb growing naturally in wet soil and shallow waters. In addition to the medicinal use, recently this plant has been recommended as an agent for phytoremediation due to the capacity of absorption and accumulation potential. Earlier studies on the effect of Hg and Cd proved that bioaccumulation of these metals taken place in all parts of plant body, but during prolonged growth, the accumulated quantity is found to be reduced. It has already been reported that phytovolatilization is one of the mode of removal of Hg and Cd from the plant body. In the present study an attempt is made to confirm the process of phytovolatilization by cultivating the root cuttings of Bacopa monnieri in Hoagland solution artificially contaminated with known quantities of Hg and Cd. The“PHYTOVOL-EXTRACTOR” was fabricated to measure the quantity of Hg and Cd liberated from the plant to atmosphere. In this system, plants growing in Hoagland solution were placed inside a transparent glass chamber fitted with provisions for intake of water-filtered air and exhaust for transpired-water providing estimation of Hg and Cd content liberated from the plant through the stomata. It is inferred that in Bacopa monnieri, phytovolatilization is the main mode of sequestration to make its possibility in environmental assessment of environmental pollution.key words: Bacopa monnieri, Phytovolatilization, Heavy metals, Detoxification, Phytovol- extractor, Sequestration, Phytoremediation, Environmental Assessment
