| Summary: | Heavy metal pollution had becoming one of the most serious environmental
problems today. These pollutants have highly affected agricultural productivity,
human health as well as disrupting the world’s ecological biodiversity system.
Experimental research conducted had undergone the phytoremediation process
which is bio-based low cost alternative technology, environmental friendly and
represents the efficiency of using plants for treatment of heavy metal.
Bamboos are potentially good plants for phytoremediation due to their
widespread distribution, simple and well-known propagation mode, the full
range of species and their potential as an additional use for raw material. They
are fast-growing, grow more rapidly than other timber species and have
various actual and possible applications for income generation and
environmental conservation. This study aims in evaluate the potential of B.
vulgaris as phytoremediation agent for heavy metal. The plants were grown up
uniformly in lysimeter pot for three months in the presence of heavy metal
copper, zinc and iron with different level of concentration to quantify the toxic
effects of these metals on morphological and physiological attributes of B.
vulgaris. Leachates from lysimeter were being collected periodically and
undergoing screening process to determine the contents of remaining heavy
metal in samples. The close positive relationship of heavy metal analysis that
exhibits low concentration of metal before and after treated or infiltrated by B.
vulgaris indicates that it can be used as bioaccumulator plants of heavy metal
pollution by absorbing excess heavy metal from the polluted soils and water.
From the study, B. vulgaris most efficient in uptake iron compared to zinc and copper. The findings indicated that heavy metals copper zinc and iron are
considered to be important for plant growth due to the positive response in
morphological and physiological attributes of B. vulgaris at low concentration
however brings phytotoxicity effects at high level of concentration and time.
B.vulgaris performance was increased at early weeks and in low concentration
metal level indicated it’s tolerance to the heavy metals, making it a prospective
phytoremediator species. Thus, we can conclude that B. vulgaris has potential
to be a phytoremediator plant and can be grown up on moderately heavy
metal contaminated soil. |
