Abstract:
This study was conducted at Terengganu River were the specific location for
sampling station is Pulau Manis River, Rengas River and Pulau Rusa River. The aim
for this study is to determine and compare the concentration of heavy metal (Cu, Cd
and Zinc) in Corbicula jluminea and sediment collected from three stations at
Terengganu River and determines the concentration of Cu, Cd and Zinc in different of
size of Cjluminea. Cjluminea was collected by hand while the sediment was
collected using plastic spatula that it was rinse with 5% nitric acid. Samples were
brought back to laboratory and store in refrigerator for further analysis. lbree
separation size were been done in Cj
luminea (large, medium and small) to analysis
their heavy metal concentration at different size. The samples were dried and digested
to detect the heavy metal concentration (Cu, Cd and Zn), using Inductively Coupled
Plasma-Mass Spectrometry or ICPMS. The result showed that Cjluminea has high
concentration of Zinc (19.0397 ± 4.09 µgig to 22.1605 ± 4.88 µgig) than other metaJs
and higher concentration of Zinc also had been detected in the sediment. The
concentration of Zinc in sediment is 0.9204 ± 4.09 µgig to 4.4090 ± 6.98 µgig depend
the location of the station.
