Global ban on organotin ship paints proposed by UN maritime group

Article Abstract:

Government representatives at an April 1998 meeting of the United Nations' International Maritime Organization have proposed to ban the use of organotin biocides in ship anti-fouling paints, including tributyl tin (TBT). TBT-based paints have been linked to sex changes in shellfish and other harmful effects in other marine creatures. The IMO could formally adopt the proposal as early as 1999 and be ready for ratification by the 155 IMO member nations. Organotin paints are widely used to deter the growth of marine creatures on ship hulls and other marine structures.
