Resumo |
Imposex is the development of male sexual characteristics, i.e., penis and/or vas deferens in females of dioecious gastropods. This phenomenon has been associated to the use of the organotin based marine antifouling paints and used worldwide as a bioindicator of pollution by the TBT (antifouling agent) as well as to evaluate the related ecological impact. This study reports imposex in Stramonita haemastoma at south coast of Rio de Janeiro State (Brazil), specifically at Sepetiba and Ilha Grande Bays. All the stations where snails were found have shown imposex. Ilha Grande Bay presented the highest values of imposex indices when compared to Sepetiba Bay. The results suggest that high concentration of shipping activities and coastal morphology are the principal causes at the most polluted sites. |
