O imposex é um excelente marcador da contaminação marinha por compostos orgânicos de estanho (COEs). Esse fenômeno consiste no surgimento de caracteres sexuais masculinos mensuráveis, em fêmeas de neogastrópodes. Um ...

The first appraisal of butyltins(BT)contami- nation linked with imposex incidence in the Pacific coast of South America was performed in the current study.Imposex occurrence was analyzed in three muricid species (Thaisbiserialis, ...

Compostos organoestânicos(COEs) são utilizados em tintas de ação antiincrustrante aplicadas a embarcações do mundo inteiro, tendo-se revelado altamente tóxicos para diversos componentes da biota marinha. Em mamíferos, os ...

Os compostos orgânicos de estanho são utilizados desde a década de 1970 como princípio ativo de tintas anti-in- crustantes aplicadas a embarcações. Já na década de 1980, os efeitos tóxicos desses compostos foram detectados ...

Imposex is characterized by the development of male characteristics, such as the penis and vas deferens, in female prosobranch gastropods, caused by organotin compounds contamination. In Brazil, imposex was observed in the ...

Imposex is the occurrence of male sexual features in female prosobranch mollusks exposed to organotin compounds. Since imposex has measurable characteristics, it has been used as a bioindication tool for the presence of ...

Marine organisms are affected by organotin compounds due to the cumulative, deleterious effects of these latter. The most evident and well known consequence of organotin contamination is imposex, a hormonal disruption that ...
