Resumo: | Imposex in gastropod mollusks is an efficient and low-cost biomarker for pollution by organotin compounds. Such substances are typically found in areas with an intense flux of vessels, such as marinas and harbors. This study preliminarily evaluated the occurrence of imposex in Stramonita haemastoma (Linnaeus, 1758) populations along the areas under the influence of the main harbors from southern Brazil (Paranaguá, PR; São Francisco do Sul, SC; Itajaí, SC; and Rio Grande, RS). Although no chemical analyses were performed so far to confirm the presence of organotins, the occurrence of imposex strongly suggests a contamination by these compounds in the studied areas and it is likely that the closest from the harbors (as the main sources) the more contaminated the environment. However, due to the ilimitations of S. haemastoma, it is important to assess the response of alternative species adapted to mesohaline environments and non-consolidated substrates, in order to make up for the lack of indicator species for some areas such as Patos Lagoon and Itajaí-Açu estuaries. |

Esses compostos são tipicamente encontrados em áreas com intenso fluxo de embarcações, como marinas e terminais portuários. O presente estudo verificou preliminarmente a ocorrência de imposex em populações de Stramonita haemastoma (Linnaeus, 1758) ao longo das áreas sob a influência dos principais terminais portuários do sul do Brasil(Paranaguá, PR, São Francisco do Sul, SC, Itajaí, SC, e Rio Grande, RS). Apesar de não confirmados quimicamente, a ocorrência de imposex em todas as áreas estudadas sugere contaminação por compostos orgânicos de estanho, sendo possivelmente tanto maior quanto mais próxima dos portos (ou das fontes). Porém, em razão das limitações de S. haemastoma, é importante avaliar essa resposta em espécies alternativas que suportem ambientes mesohalinos e com substratos não consolidados, possibilitando assim avaliação mais completa de ambientes como os estuários da Lagoa dos Patos e Itajaí-Açu.2011-05-06T13:10:32Z2011-05-06T13:10:32Z2007info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCASTRO, I.B. ; BEMVENUTI, C.E ; FILLMANN, G. .
