The increasing incidence of imposex in Stramonita haemastoma (Mollusca: Gastrop...
Castro, Ítalo Braga de; Meirelles, Carlos Augusto Oliveira de; Pinheiro, Jully Cristiny Lopes; Cascon, Helena MatthewsImposex is characterized by the development of masculine sexual organs in neogastropod females, caused by organotin contamination of the seawater. These compounds, as tributyltin (TBT), are used world-wide as biocidal agents in antifouling paints, commonly used to covering boats and off shore metallic structures. Five sampling sites were determined along the coast of Ceará State, Northeast Brazil in March 2001....
Compostos organoestânicos: um risco potencial para contaminação do pescado marinho
Braga, Anna Rafaela Cavalcante; Castro, Ítalo Braga de; Rocha-Barreira, Cristina de AlmeidaOrganotin compounds (OTCs) are used in antifouling paints applied on boats all over the world, having shown to be highly toxic to different components of the marine biota. In mammals the effects of contamination from organotin compounds are: imunosuppression, reproduction changes and citotoxicity. Research work carried out off the Suva peninsula, in Fiji, and the Guanabara Bay, in Brazil, has shown the existing...
Compostos orgânicos de estanho: efeitos sobre a fauna marinha – uma revisão
Castro, Ítalo Braga de; Queiroz, Liana Rodrigues; Barreira, Cristina de Almeida RochaThe organotin compounds are used since the1970’s in antifouling paints applied in ships. In the 1980’s the toxic effects of these compounds were detected in oyster Crassostrea gigas cultivated at Arcachon Bay, France. Since then, many organisms around the world have shown the symptoms of this kind of contamination. The present study tried to catalogue most of the marine organisms identifi ed down to genus or sp...

Castro, Ítalo Braga de; Cascon, Helena Matthews; Fernandez, Marcos AntônioO imposex caracteriza-se pelo surgimento de caracteres sexuais masculinos, sobretudo pênis e vaso deferente, em fêmeas de moluscos neogastrópodes. O fenômeno é provocado pela contaminação da água do mar e/ou da dieta alimentar dos animais por Tributilestanho (TBT) oriundo das tintas de ação “antifouling” utilizadas em muitas embarcações. Para verificar a existência do problema na costa de Fortaleza e de parte d...
