Status of heavy metals concentrations in oysters (Crassostrea sp.) from Setiu wetlands, Terengganu, Malaysia = Status kepekatan logam berat dalam tiram (Crassostrea sp.) dari tanah bencah Setiu, Terengganu, Malaysia

This study aimed at documenting the potentially toxic metal levels in oysters from the aquaculture area of the Peninsular Malaysia east coast. Concentrations of essential (Zn and Cu) and non-essential (Pb and Cd) heavy metals were analyzed in total soft tissue, different sex, selected organs and she...
