Abstract

Fishes are considered as good indicators of trace metal pollution in
the aquatic ecosystem in addition to being a good source of protein.
Thus, the concentration of trace metals (Fe, Zn, Al, As, Cd and Pb) in
water and muscle, liver and gills tissues of two important marine fish
species, Arius maculatus and Pennahia anea collected from Kapar and
Mersing in Peninsular Malaysia, were examined. Generally, Fe has the
highest concentrations in both water and the fish species. While, Cd in
both coastal waters showed high levels exceeding the international
standards. The metal level concentrations in the fish samples are in the
descending order from livers > gills > muscles. Fortunately, level of
these metal concentrations in fish has not exceeded the permitted level
of Malaysian and international standards.
