dc.description.abstract | In a dry dock, large quantities of particulate pollutants including antifouling paint and metallic particles are emitted into the adjacent sea from vessel repair, maintenance and cleaning processes. We investigated TBT and metals contaminations of bottom sediments near shipyards of a small marina located in Busan, Korea and found that they were highly contaminated with TBT and Cu, Zn, and other metals. To better understand their environmental impacts and to make an optimal remediation plan, we characterized individual antifouling fragments in terms of metal and TBT contents, magnetic properties and grain size. Individual antifouling fragments exhibited simultaneously high levels of TBT and metals and high magnetic susceptibility appeared to be a major source of pollution in the bottom sediment. Individual antifouling fragments exhibited simultaneously high levels of TBT and metals and high magnetic susceptibility appeared to be a major source of pollution in the bottom sediment. Therefore, the magnetic separation in combination with size-separation appears to be effective remediation method to remove the TBT and metals contaminated shipyard sediments. The operational detail on this separation scheme is currently being under examined using a bench-scale pilot.ions of bottom sediments near shipyards of a small marina located in Busan, Korea and found that they were highly contaminated with TBT and Cu, Zn, and other metals.
