Tributyltin oxide is a potent skin irritant.
Tributyltin compounds had been used as marine anti-biofouling agents. Concerns over toxicity of these compounds (some reports describe biological effects to marine life at a concentration of 1 nanogram per liter) have led to a world-wide ban by the International Maritime Organization. It is now considered a severe marine pollutant.
