| Summary: | Mangrove forest ecosystems are threatened by direct impacts such as cutting and pollution due to
agricultural, industrialization and urbanization activities. Mangrove forests are often regarded as
unpleasant environments with little intrinsic value. Mangrove forests perform valued regional and
site-specific functions. Mangrove species can take up excessive nutrients and also play a crucial
role in creating a favourable environment for a variety of chemical, biological and physical
processes that contribute to the inorganic removal and degradation of organic compounds. Of the
many mangrove species Sonneratia alba, Avicennia alba and Rhizophora apiculata have been
studied for biomonitoring of toxic heavy metals elements (Fe, Cu, Zn, Pb and Mn) in a wide range
of plant tissues (roots and leaves) and sediment composition at three different locations in Negeri
Sembilan, west coast of Malaysia. The results established that there were significant differences
between the three mangrove species, locations, plant tissues and sediment samples and their
interaction for all the five heavy metals content. The findings revealed that leaf tissues for all
species accumulated mostly Fe, Zn, Pb and Cu. Interestingly we noticed that different localities
will accumulate different type of heavy metals, for instance R. apiculata leaf tissues were detected
with higher concentration of Cu and Pb at Kampung Sungai Sekawang whereas in another two
sites were detected with Cu, Fe, Zn and Pb. S. alba indicated that the most heavy metals highly
accumulated was Zn followed by Pb and Cu. In this study A. alba showed Zn was highly
accumulated in leaf tissues at Pasir Panjang. Thus, those three mangrove species appear to have
the greatest potential for use as an effective ecological indicator tools for inorganic contaminants
monitoring in mangrove ecosystems |
