ABSTRACT: Surface
sediments and giant mudskipper (Periophthalmodon
schlosseri) were collected in August and September 2008 and in March and
June 2010 from six sampling sites in the west coast of Peninsular Malaysia to
assess heavy metals accumulation in the giant mudskipper. Sequential extraction
technique was used to fractionate the sediments into four different geo-chemical
fractions; easily, freely or leachable and exchangeable (EFLE), acid reducible,
oxidizable organic and resistant fractions. Heavy metals concentrations (Cu,
Zn, Pb, Cd and Ni) in the surface sediments and giant mudskipper were
determined by using air acetylene flame atomic absorption spectrophotometer
(AAS) Perkin Elmer Analyst 800. The results of Pearson’s correlation analyses
showed that metal concentrations in the tissues of P. schlosseri were significantly correlated (p p P. schlosseri and 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 the four fractions of Pb), Cd and Ni in P.
schlosseri and Cd and Ni in the sediment (with all fractions of Cd and Ni
except acid-reducible Cd and Ni) which might suggest the use of P. schlosseri as a biomonitoring agent
for heavy metals pollution in the west coast of Peninsular Malaysia.
