【 摘 要 】

The objective of the present study was to analyze spatial distribution potential ecological risk of heavy metals in North-West Coast of Kundur Island. Sampels of seawater and sediment were taken from five stations and were analysed by using AAS Perkin Elmer 3110 in Marine Chemistry Laboratory Faculty of Fisheries and Marine Science, Universitas Riau. The arrangement of the metals studied from higher to lower mean concentrations are: Fe>Ni>Zn>Mn>Cr>Sn>Pb>Cu in seawater and Fe>Mn>Zn>Ni>Cr>Pb>Sn>Cu in sediments, respectively. Distribution of heavy metal concentrations in seawater and sediment were found to have almost similar trends where higher concentrations were found in stations closed to the mining activities. Concentration of all metals in seawater were possitively correlated with that in sediment, except for Mn. Contamination factor, geoaccumulation index and enrichment factor demonstrated that most of the sediment samples were moderately to heavily contaminated by Cr, Ni and Zn but not yet for other metals. However, PERI value indicated that the studied area is still has low ecological risk from the mining activity in the surrounding area.
