Tributyltin (TBT) is an aggressive biocide that has been used in anti-fouling ship paints since the 1970s. The toxicity of TBT prevents the growth of algae, barnacles and other marine organisms on ship hulls. However, TBT leaches from the paint and enters the marine environment. TBT accumulates in sediments, especially in areas with a high density of ship movements such as harbours and ports. From 1 January 2003, the use of TBT in anti-fouling systems on ships was banned, following a decision taken by the International Maritime Organisation (IMO) and Commission Directive 2002/62/EC of 9 July 2002 on organostannic compounds. In order to prevent desorption from sediments reintroducing TBT into the marine environment, effective removal and treatment methods for TBT contaminated sediments need to be implemented. This project aims at demonstrating an integrated approach to eliminating TBT from the marine environment that includes prevention, removal, treatment and finally reuse.
