Abstract

The objective of this study is to evaluate the contamination of sediments, in order to determine a remediation method for a local bay bottom. To achieve this, 12 surface-sediment samples were obtained from a wood pool located in the inner part of Shimizu Port, Japan, and were subjected to physical and chemical analyses. The results show that the concentrations of the heavy metals measured were relatively high. The concentrations of copper and zinc in the sediment samples were higher than the probable effect levels of marine sediments provided by the Canadian Sediment Quality Guidelines. The high concentrations obtained are probably due to the high organic content resulting from humus. The separation of organic matter might be useful as a remediation technique for dredged materials. A containment technique for dredged sediments using permeable bags is therefore proposed.
