Distribusi Spasial Logam Pb dan Cu pada Sedimen dan Air Laut Permukaan di Perairan Tanjung Buton Kabupaten Siak Provinsi Riau
Abstract: A study on the
concentrations of Pb and Cu in the surface seawater and sedimenthas been
conducted to determine the concentrations and to assess their spatial
dis-tribution in Tanjung Buton coastal waters. All water quality parameters
measuredin the present study were still in the range of tolerable levels for
the survival ofmarine organisms. Heavy metal concentrations in surface seawater
and sedimentwere found to have almost similar trend where the highest
concentrations werefound in station closed to the most populated area in the
former port area. Concen-trations of Pb in both seawater and sediment were
higher than Cu. Vertical distribu-tion of Cu in sediment were clearly noticed
where the concentration in deeper layerwere found to have higher concentration
when compared to the upper layers (al-though they were statistically non
significant) which shows the effects of anthropo-genic activities in the former
port area. Concentration of Pb in seawater were possi-tively correlated with
that in sediment (y = 15,58 + 5,573x; r = 0,31), whilst Cushows negative
correlation (y = 0,91 - 10,5x; r = 0,1). Higher concentration ofheavy metals
was assumed to be related to an increase in population inhabited thesurrounding
waters and anthropogenic activities such as dumping of debris, ports,boat
traffic and other anthropogenic sources. In general, the concentrations of
Pband Cu in Tanjung Buton coastal waters were comparatively lower than
reportedvalues in regional studies. As the ever increasing human activities and
rapid devel-opments in many infrastructures and industry sectors, a continuous
environment monitoring program should be implemented to keep and protect the
sustainableTanjung Buton coastal resources.
