Concentration of heavy metal (cooper, zinc and cadmium) in Corbicula fluminea collected from Terengganu river

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.
