Imposex induction in Stramonita haemastoma floridana (Conrad, 1837) (Mollusca: Gastropoda: Muricidae) submitted to an organotin-contaminated diet

Brazilian Journal of Oceanography, 2006
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 causes a superimposition of ...

Efeito biocida de mandelatos organoestânicos sobre Fusarium oxysporum f. sp. cubense Biocide effect of organotin mandelates on Fusarium oxysporum f. sp. cubense

Ciência e Agrotecnologia, 2004
Compostos organoestânicos são substâncias que têm sido utilizadas como biocidas. A vantagem do uso dessa classe de compostos é sua degradação em dióxido de estanho (SnO2), que é atóxico para o meio ambiente.

Imposex in endemic volutid from Northeast Brazil (Mollusca: Gastropoda)

Brazilian Archives of Biology and Technology, 2008
Imposex is characterized by the development of masculine sexual organs in neogastropod females. Almost 120 mollusk species are known to present imposex when exposed to organic tin compounds as tributyltin (TBT) and triphenyltin (TPT). These compounds are

Imposex in Stramonita haemastoma from coastal sites of Cartagena, Colombia

Brazilian Journal of Biology, 2017
Imposex is the development of male sexual characteristics caused by the toxic effects of some chemicals that acts as an endocrinal disruptor. Antifouling paints contain these chemicals.

Occurrence of imposex in Thais haemastoma: possible evidence of environmental contamination derived from organotin compounds in Rio de Janeiro and Fortaleza, Brazil Ocorrência de imposex em Thais haemastoma: possíveis evidências de contaminação ambiental por compostos organotínicos no Rio de Janeiro e em Fortaleza, Brasil

Cadernos de Saúde Pública, 2002
There are indications that the widespread use of organotin compounds (TBT and TPT) as antifoulings, as stabilizers in plastic and as pesticides, has severely affected several species of marine organisms.

Organotin pollution at Arraial do Cabo, Rio de Janeiro State, Brazil: increasing levels after the TBT ban

Brazilian Journal of Oceanography, 2011
Imposex, an endocrine disruption phenomenon, is a biomarker of tributyltin (TBT) exposure in marine gastropod populations. The occurrence and intensity of the syndrome in populations of the neogastropod Stramonita haemastoma were ascertained at nine ...

Imposex in Thais rustica (Mollusca: Neogastropoda) (Lamark, 1822) as an indicator of organotin compounds pollution at Maceio coast (Northeastern Brazil)

Brazilian Journal of Oceanography, 2004
The use of OTC (organotin compounds) as biocides in naval antifouling paints causes impacts on non-target organisms. One of these impacts is a syndrome called imposex in gastropod molluscs.

Suscetibilidade de populações de Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) a acaricidas organoestânicos em citros

Scientia Agricola, 2001
Brevipalpus phoenicis (Geijskes, 1939) é uma das principais pragas da cultura de citros no Brasil. Os acaricidas organoestânicos representam mais 40% da área tratada de citros para o controle de B. phoenicis.
