The distribution of Co, Pb and Zn in the bottom sediment offshore of Kemaman, Terengganu, Malaysia during pre and post monsoon periods

This study focussed on heavy-metal concentrations in sediment off the coast of Kemaman. Sampling was conducted at 21 stations during the pre-monsoon and post-monsoon seasons. Sediment was analysed for total concentration of Co, Pb and Zn using ICP-MS after total acid digestion. The grain size of the...
