Dogwhelks Nucella lapillus became locally extinct on some shores adjacent to areas of high shipping/boating activity during the period of high tributyltin (TBT) contamination in the 1980s and early 1990s. However, the species has now re-colonised sites at which extinction occurred on the Isle of Cumbrae, the northeast coast of England. the Shetland Isles and Southwest England. There have also been substantial declines in the severity of imposex on adjacent shores where the species has persisted during this period, Recolonisation and recovery can be attributed to two measures: regulations prohibiting the use of TBT-based paints on vessels <25 m in length and the development of slow-releasing. self-polishing copolymer paints'. Nevertheless, the International Maritime Organisation has now imposed a total ban on the use of TBT-based paints as antifoulants. This is almost certain to result in the use of paints containing alternative biocides and there is widespread concern that there is relatively little information on which to assess their likely environmental impacts. They could cause substantial environmental damage. (C) 2002 Elsevier Science Ltd, All rights reserved.
