Review of Antifouling Marine Coatings and Their Influence on Marine Environments.

摘要

The problem of marine 'fouling' and corrosion of ship hulls and marine installations is well known and has been attacked by many research and development groups. The problem is particularly acute in south Louisiana where the brackish and salty water of the wetlands constitute one of the worse fouling areas in the world. The only practical solution to these fouling problems through the years has been the utilization of paints and coatings having antifoulant activity based on a toxic component. Currently, the most successful systems appear to be those containing organoting toxicants. As these materials find ever increasing utility and application in the marine industry and in naval operations, their long-term environmental impact on harbors and shipyards will become more important. The assessment of this environmental insult to the wetlands areas of south Louisiana is dependent on our ability to quantify the release of toxicant to the biosphere and to follow the biochemical pathway of the toxicant from release to eventual degradation as innocuous inorganic tin.
