Levels of TBT and other selected organotin compounds in duplicate diet samples
Sousa, Ana C. A.; Coelho, Sónia; Pastorinho, M. Ramiro; Taborda Barata, Luis; Nogueira, António J.A.; Isobe, Tomohiko; Kunisue, Tatsuya; Takahashi, ShinOrganotin compounds (OTs) are ubiquitous contaminants with a broad range of applications ranging from biocides and pesticides to catalysts for the production of polyurethane foams and silicones. The deleterious effects of some OTs (particularly tributyltin - TBT) upon wildlife and experimental animals are well documented and include endocrine disruption, immunotoxicity, neurotoxicity, genotoxicity and metabolic...
A microcosm approach to evaluate the degradation of tributyltin (TBT) by Aeromo...
Cruz, Andreia; Henriques, Isabel; Sousa, Ana C. A.; Baptista, Inês; Almeida, Adelaide; Takahashi, Shin; Tanabe, Shinsuke; Correia, AntonioTributyltin (TBT) is a biocide extremely toxic to a wide range of organisms, which has been used for decades in antifouling paints. Despite its global ban in 2008, TBT is still a problem of great concern due to the high levels trapped in sediments. Aeromonas molluscorum Av27 is a TBT degrading bacterium that was isolated from an estuarine system. We investigated the ability and the role of this bacterium on TBT...

History on organotin compounds, from snails to humans
Sousa, Ana C. A.; Pastorinho, M. Ramiro; Takahashi, Shin; Tanabe, ShinsukeOrganotin compounds are industrial chemicals used as biocides, polyvinyl chloride stabilizers and industrial catalysts for the manufacture of silicone and polyurethane foams. Despite multiple applications, organotin notoriety is due to tributyltin, a potent biocide used in antifouling paints. Because of the intensive use of tributyltin for the protection of ships’ hulls, tributyltin has been largely released in...
Organotin levels in Nazare canyon (west Iberian Margin, NE Atlantic) and adjace...
Sousa, Ana C. A.; Oliveira, Isabel B.; Laranjeiro, Filipe; Takahashi, Shin; Tanabe, Shinsuke; Cunha, Marina R.; Barroso, Carlos M.Organotin compounds (OTs) are ubiquitous in the marine environment and high concentrations (mu g g(-1) range) in sediments from different coastal areas around the world have been reported. However, few reports have described the OTs contamination status in the offshore and deep sea environment. This work investigated organotin levels in Nazare canyon for the first time. Levels of monobutyltin (MBT), dibutyltin ...
