Abstract
Surface sediments collected from four sampling stations, each from the coastal area of Tanjung Pasir, Tangerang, and
coastal areas of Panimbang, Pandeglang, Banten Province have been geochemically [easily, freely, leachable or exchangeable (EFLE),
acid-reducible/Fe-Mn Oxides, oxidisable-organic and resistant] analyzed using AAS Shimadzu 6300 series. Cu, Pb, and Zn content in
sediment fraction were correlated with the respective metal concentrations in tissues of
Anadara indica
collected from the same
stations as for those sediment samples. The objective of this study was to determine the concentrations of heavy metals Cu, Pb and
Zn in sediments and
A. indica
as well as to relate the possible differences in the accumulation patterns of Cu, Pb and Zn in
A. indica
to those in the geochemical fractions in the surface sediment. The results revealed that heavy metal concentrations were recorded to
be higher in stations closed to the industries and anthropogenic activities (Garapan rivermouth, Tanjung Pasir) compared to
agricultural activities (Cibungur rivermouth, Panimbang). Significant (p < 0.01) correlations were observed between Cu in the soft
tissue of
A. indica
with exchangeable, Fe-Mn oxides, oxidisable organic, residual fractions of Cu in the sediment, and Fe-Mn oxides,
oxidisable organic, residual fraction for Pb, while significant correlations were observed between Zn in soft tissue of
A. indica
with
Fe-Mn oxides and oxidisable organic fractions. It is suggested that the soft tissue of
A. indica
could be used as a useful biomonitoring
agent for Cu, Pb, and Zn pollution.

Introduction
Nowadays, detectable trace metal contamination
occurs in many aquatic environments as a result of
human activities. The biological impacts of that
contamination are poorly understood (Cairns, 1984),
especially the processes that control accessibility of
metals to aquatic biota (i.e. the biological availability)
(Luoma, 1983). Sediments constitute a concentrated
pool of metals in aquatic environments. Thus,
understanding metal bioavailability from sediments is
especially important.
Lead is a naturally occuring metal found in small
amounts in the earth’s crust. It can be found in all
parts of our environment. Lead (Pb) may be present in
hazardous concentrations in food, water, and air.
Sources include paint, urban dust, folk remedies,
mining, smelting and non-ferrous metal industries.
Lead poisoning is the leading environmentally
induced illness in children. At greatest risk are children
under the age of six because they are undergoing rapid
neurological and physical development.
Copper (Cu) is used in manufacturing of steel
foundries, etc. Copper (Cu) exists in the final effluent
as dissolved species representing as much as 80 % of
the total concentration, and they are most bioavailable
form. It tends to have a high affinity for the clay/silt
fraction (Bubb et al.,
1991) and invariably highly
complex in polluted and unpolluted freshwater
(Moriber, 1974).
Zinc (Zn) is among the most prevalent of metal
contaminants in the environment, especially in
aerobic water. A significant fraction is likely to exist
as simple ionic forms such as carbonate and hydroxyl
