Abstract:
The focus of this study was to determine the merc
ury distribution in sediment and also
to study about relationship between Hg concentration and mean particle size of
sediment and total organic carbon at Terengganu river Estuarine sediment and also its
relationship with changes of monsoon season.Sampling was done for twice and for
each sarnpling,involving 1 O.Concentration of Hg was determined using ICP
MS.According to the result,distribution of Hg concentration varied from 0.00520.0112
µgig for first sampling (Pre Monsoon) and 0.1738-0.3878 µgig for second
sampling (Post Monsoon).For the correlation between Hg concentration with mean
particle size for Pre Monsoon sampling,it shows almost negligible correlation
(r=0.1844) while for sampling Post Monsoon,it shows low correlation with mean
particle size (r=0.361 ).Hg concentration has almost negligible correlation with
sampling stations for first sampling (r=0.0632) and for the second sampling.Hg
concentration has moderate correlation with sampling stations (r= 0.4550).Correlation
between Hg concentration before Pre Monsoon and Post is low (r=0.2449).Besides
that,Hg concentration has moderate correlation with organic carbon for both
sampling.From the result �overall almost stations which was analysed have
Hg concentration exceed the Hg concentration in uncontaminated sediment which is
0.05 µgig for second sampling (Post Monsoon).
