The concentration of selected heavy metals in the sediment at Sungai Terengganu
estuary was been investigated. Objective of this study is to determine the
concentration of heavy metal in sediment from Sungai Terengganu estuary and to
identify the level of pollution. The selected metal are Al, Li, Cr, Ni, Cu, Hg, Pb with
average value of 8.846%, 42.254 mg/kg, 14.711 mg/kg, 7.297 mg/kg, 6.017 mg/kg,
0.209 mg/kg and 12.794 mg/kg respectively. Majority of the metals tested have higher
concentration near the mouth of the estuary. The result from enrichment factor (EF)
and geo accumulation index (Igeo) suggested that anthropogenic sources are the
most significantly enriched by selected metals. It is possible from the boating activities
and changing of the ballast water in the estuary area. This work is important as it can
help in determining the changes as it can be to monitor and manage in the future.
