Organotin compounds are chemical compounds that contain tin bonded to carbon and are used in various applications, including as stabilizers in plastics and as biocides in marine antifouling paints. They are known for their effectiveness in preventing the growth of barnacles and other marine organisms on ships and boats. However, organotin compounds can be toxic to aquatic life and may pose environmental risks. Due to their harmful effects, regulations have been implemented in many countries to limit their use, particularly in products that come into contact with water, to protect ecosystems and human health.
