Abstract

The distribution, accumulation and enrichment of trace metals in sediments of Sepangar Bay, Sabah were investigated. Sediment samples from 12 locations of Sepangar Bay were collected and characterized for trace metals (arsenic (As), calcium (Ca), cadmium (Cd), chromium (Cr), copper (Cu),iron (Fe), lituem (Li), magnesium (Mg), manganese (Mn), nikel (Ni), lead (Pb), titanium (Ti), vanadium (V) and zinc (Zn)), organic matter and grain size. Result showed that the concentration of one potentially toxic metal (Cd) and four essential metals (ca, Mg, Mn and Zn) in some locations of Sepangar Bay were higher than the recommended value of metals in sediment by FAO/WHO and USEPA guidelines, and Pollution Load Index (PLI). The baseline concentrations of V, Ti, Pb, Mn, Li, Fe and Zn were 30.48 mg/kg, 0.0321 %, 6.98 mg/kg, 157.22 mg/kg, 35.49 mg/kg, 1.021% and 46.57 mg/kg, respectively. The concentration of most metals was comparable to the baseline, except for Mn and Zn which showed higher enrichment in most parts of Sepangar Bay. In conclusion, most of the trace metal concentrations, except Cd in Sepangar Bay is still within the permissible levels and should not cause threats to public health.
