Antifoulants In 1998, Rohm and Haas Company received a Presidential Green Chemistry Challenge Award for designing the environmentally safe marine antifoulant called Sea-Nine™. Fouling, the unwanted growth of plants and animals on a ship's surface, costs the shipping industry approximately $3 billion a year. A significant portion of this cost is the increased fuel consumption needed to overcome hydrodynamic drag. The main compounds used worldwide to control fouling are organotin antifoulants, such as tributyltin oxide (TBTO). They are effective at preventing fouling, but have widespread environmental problems due to their persistence in the environment and the effects they cause, including acute toxicity, bioaccumulation, decreased reproductive viability, and increased shell thickness in shellfish. Rohm and Haas Company sought to develop an antifoulant that would prevent fouling from a wide variety of marine organisms without causing harm to nontarget organisms. Compounds from the 3-isothiazolone class were chosen. In particular, 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one was selected as it was found to degrade extremely rapidly in seawater and even faster (1 h) in sediment. TBTO bioaccumulates as much as 10,000 times, while Sea-Nine™ bioaccumulation is essentially zero. Both TBTO and Sea-Nine™ were acutely toxic to marine organisms, but TBTO had widespread chronic toxicity, while Sea-Nine™ antifoulant showed no chronic toxicity. |
