Webmeasures have been suggested but tributyltin self-polishing copolymer (TBT-SPC) paints have been the most effective and commercially viable option in curbing biofouling. However, leaching of tri-organotin biocides from TBT-SPC paints through self-polishing activity constitute pollution which led to the ban of biocide-base paints. Webgradually replaced by ‘self-polishing copolymer’ formulations which ensured a more constant release of biocide and reduced repainting frequency. At the same time as its explosive increase in use, the first observations were made of TBT effects on non-target organisms. While toxicity to fouling organisms was intentional,
