On our previous sampling trip a sediment samples were collected from 6 sampling stations along the Merbok river catchment. Sediments were obtained by using sediment grabber (Figure 1) which is handled by two person on a boat. The sediment grabber capable to grabs approximately 1kg of wet sediments. The collected sediments then were stored in a labelled plastic bag container. Samples analysing will be conducted in the laboratory to examine its heavy metal substances.
