Fstbttms - Tributyl-Tin based paints were not outlawed in the US due to quantitative scientific measurement - they were outlawed due to environmental lobbying groups being successful in showing qualitative, anecdotal, non-labaratory based evidence of reduced growth of aquatic species in areas frequented by boats. Because of the higher levels of TBT found in these areas, it was pointed to as a possible reason for this lesser growth, and because many alternatives were available, the environmentalists were able to push through - very rapidly, I may add - legislation banning its use. The legislation was not because of potential harm to humans. Many studies show that you have to have significant concentrations of TBT for it to cause issues in humans, and the paint industry (yes, I know there is a conflict interest in this source) says that TBT will metabolize within 3 days.
