LEACHING AND DEGRADATION OF ANTIFOULING PAINTS IN SEAWATER

Organotin compounds in antifouling paints are recognized as one of the best chemical substances to prevent adhesion of aquatic life to the underwater surfaces of a ship and thus reducing fuel consumption at sea. The toxicity of organotin to marine life has caused concern in recent years. The Environmental Protection Committee of the International Maritime Organization have discussed measures to restrict the content and leaching rate of organotin. To determine the minimum rate of organotin compound required for antifouling, ship navigation tests, sea immersion tests, and circulating water channel tests were conducted for antifouling paints currently in use and also experimental paints which contain less organotin. Degradation tests of triorganotin under seawater were carried out under varying conditions of irradiation and/or microorganisms. Data for marine environmental impact assessment was obtained. The leaching and degradation tests for organotin may be applicable to other antifouling paints.
