“…Similar results have been observed worldwide: on the northeastern Brazilian coast, in relation to S. rustica (Castro et al, 2007(Castro et al, , 2008, in the Mediterranean, in relation to Hexaplex trunculus (L.) (Axiak et al, 1995), and in several harbors in Europe and in Halifax harbor, Canada, in relation to Nucella lapillus (L.) (Sousa et al, 2009). Other studies have also confirmed that areas near harbors and marinas are hotspots for TBT pollution (Barroso et al, 2002;Sousa et al, 2005).…”

This study investigated the effects of tributyltin (TBT) on the morphology of the genital system of the gastropod Stramonita rustica in southern Bahia, Brazil. For this, 330 specimens were collected during the summer of 2014 at eight sampling points to ascertain whether male sex organs had developed in addition to the complete female genital tract in females (= imposex). The analyses were made under a stereoscopic microscope. Imposex and their associated indexes, and the sterile females, exhibited the highest rates in harbors and shipyards areas. Despite the total ban of TBT in anti-fouling paints on a global scale since 2003, the results of this and other studies indicate the continued use of those paints on the Brazilian coast. This shows the inefficiency of existing legislation and the need to strengthen enforcement of the ban.Keywords: antifouling, sterilization, harbors, TBT. Avaliação da contaminação por tributil-estanho baseada em imposex em Stramonita rustica (Mollusca: Gastropoda) ao longo do Litoral Sul da Bahia ResumoEste estudo investigou os efeitos de tributil-estanho (TBT) sobre a morfologia do sistema genital do gastrópode Stramonita rustica (Lamarck, 1822) no Litoral Sul da Bahia, Brasil. Para isso, 330 espécimens foram coletados durante o verão de 2014 em oito pontos de amostragem, para verificar se os órgãos sexuais masculinos tinham se desenvolvido para além do trato genital feminino completo (= imposex). As análises foram feitas sob um microscópio estereoscópico. O imposex e seus índices associados, assim como as fêmeas estéreis, apresentaram as maiores taxas em áreas portuárias e estaleiros. Apesar da proibição total do TBT em tintas anti-incrustantes em escala global desde 2003, os resultados deste e de outros estudos indicam a continuidade de uso dessas tintas na costa brasileira. Isso mostra a ineficácia da legislação vigente e reforça a necessidade de se cumprir integralmente o banimento.Palavras-chave: antifouling, esterilização, portos, TBT.

“…OT mean concentrations in sub-surface waters in 2006 varied from 0.7 to 140.8 ng Sn per l, the major fraction of which is known to be butyltins, as other OT species are almost negligible in quantity along the Portuguese coast. 15,34,35 However, vessels may not be the only source for these recent TBT inputs. Some authors still consider that after the IMO ban entry came into force TBT inputs were maintained by other sources, namely: (i) release from dockyard facilities as a result of the removal of old coatings in dry dock; 36 (ii) the remobilization from sediments to the water column; 37,38 (iii) some illegal use; and (iv) other sources such as preservative or disinfecting agents.…”

Nucella lapillus L. imposex levels after legislation prohibiting TBT antifoulants: temporal trends from 2003 to 2008 along the Portuguese coast

et al. 2011

Nucella lapillus (dog whelk) imposex levels were assessed along the mainland Portuguese coast in 2006 and 2008 and were compared with available data from 2003 for the same area. Given that specimen size has been described as a factor inducing variation in some of the imposex assessment indices, and thus resulting in less reliable results, new monitoring and data analysis procedures are described and applied to study change of imposex levels from 2003 to 2008. A significant decline in imposex intensity was observed in the study area during the study period, and the Portuguese coast ecological status (

“…Additionally one should not forget that organotins residues such as TBT can also be transferred to humans via dietary uptake. Sousa and co-workers predict that in traditional seafood-consuming countries the estimated Sn daily intake is high enough to cause damage to humans (Sousa et al, 2009b), making TBT contamination more than "just" an environmental issue of concern.…”

“…et al, 1999. These are largely dominated by investigations on insect growth regulators (IGRs), which are designed to act as EDCs for insect pest control, and by studies on the antifouling biocide tributyltin (TBT) that has been shown to induce imposex and intersex in prosobranch snails (Matthiessen & Gibbs, 1998;Sousa, 2009b). Imposex has been associated with skewed sex ratios, reduced fecundity, population declines, and local extinctions of affected gastropod populations (Gibbs & Bryan, 1986).…”
