A Preliminary Study of Heavy Metals in Thais gradata Collected from Kuala Sungai Ayam and Pantai Lido, Peninsular Malaysia

Abstract

This study determined the levels of Cd, Cu, Fe, Ni, and Zn in the soft tissues, operculum and shells Thais gradata between Kuala Sungai Ayam and Pantai Lido, Peninsular Malaysia, collected in 2008. The metal concentrations (µg/g dry weight) in the soft tissues of T. gradata collected from the two sites in Peninsular Malaysia ranged from 3.01-4.72 for Cd, 83.96-124 for Cu, 345-365 for Fe, 6.80-14.8 for Ni, and 2916-4361 for Zn. Overall, this preliminary baseline data can be used for regular ecological monitoring for the effective management of the coastal area in Malaysia.
