Abstract:
The concentration and distribution of heavy metals (Cd, Cu, Zn and Pb) in different size
fraction of sediment at Setiu Lagoon was carried out and the correlation between
concentration of heavy metals with size fraction ( 40 µm, 63 µm, 90 µm, 125 µm, 250 µm,
and 500 µm). Beside the sedimentological characteristics of the sediment was studied
also. Cadmium shows the very high correlation between particle size and concentration
of heavy metals. Toe r value for th.is correlation is 0.8152 with p < 0.01. It is followed by
Zinc (Zn) that also have high correlation with r value
=
0.7454, p < 0.01. The correlation
for Pb is define as moder
a
te correlation; substantial related with r = 0.6561, p < 0.01. Cu
also shows the moderate correlation with r = 0.5415, and p < 0.05. It shows that the
concentration of heavy metals are tends to decrease with increasing particles size of
sediment
