Soil exploitation due to increasing population has led to the pollution in soil.
Heavy metal pollution in soil causes toxic effect on human, plants and animals.
Phytostabilisation is the use of plant root to minimize the mobility of heavy
metal in soil. Melaleuca cajuputi has the ability to immobilize and reduce the
mobility of heavy metal. This study was conducted to determine the influence
of Melaleuca cajuputi on the mobility of heavy metal and to investigate the
mobility of Copper, Cadmium and Zinc affected by phytoremediation. The study
was conducted under greenhouse experiment whereas three heavy metals
were given which were Zinc, Cadmium and Copper at different concentration.
Heavy metal concentration was analysed using Tessier sequential extraction
method to differentiate the heavy metal concentration into fraction. The soil
properties in term of organic matter were expected to be changed due to
influence of Melaleuca cajuputi and reduce the mobility of heavy metal.
