To investigate heavy metals accumulation in giant mudskipper (Periophthalmodon schlosseri), surface sediments and giant mudskipper (Periophthalmodon schlosseri) were collected from six sampling sites on Peninsular Malaysia's west coast in August and September 2008 and March and June 2010. The goal of this study was to determine the concentrations of heavy metals in gigantic mudskippers (Periophthalmodon schlosseri) and their relationships with various geochemical fractions of sediments. The sediments were fractionated into four geochemical fractions using a sequential extraction technique: readily, freely or leachable and exchangeable (EFLE), acid reducible, oxidizable organic, and resistant fractions. The amounts of heavy metals (Cu, Zn, Pb, Cd, and Ni) in surface sediments and giant mudskipper were evaluated using a Perkin Elmer Analyst 800 air acetylene flame atomic absorption spectrophotometer (AAS). Metal concentrations in P. schlosseri tissues were significantly correlated (p 0.01 or 0.05) with Cu in the sediment (oxidisable organic, resistant, and total Cu), Zn in P. schlosseri and Zn in the sediment (EFLE and total Zn), Pb in P. schlosseri and Pb in the sediment (with all four fractions of Pb), Cd and Ni in P. schlosseri and Cd and Ni in the sediment (with all four fractions .
