Organometallic compound of tin with three phenyl groups
Triphenyltin (TPT) compounds are highly effective biocides. Along with tributyltin compounds, TPT compounds were components of many antifouling paints for ships (until about 1990). Furthermore, they are used as fungicides in agriculture. In Germany, however, registration was withdrawn in 2001.
TPT compounds enter the environment during production and use. They are lipophilic and adsorb strongly to particles. Degradation is relatively slow.
Since 2003, antifouling agents containing organotin compounds are banned in the EU, and since 2006, marketing of biocides containing triphenyltin is prohibited.
