“…VDSI is the only index that responds effectively over a broad range of imposex. It is useful in assessing the reproductive capacity of the studied population; populations with a mean VDSI above IV are comprised of sterile females, and show reduced reprodutive capacity (Gibbs & Brian, 1994;Oehlmann et al, 1996Oehlmann et al, , 1998Stroben et al, 1995). VDSI was obtained through two different approaches: (1) by using the scale of Gibbs (Gibbs & Bryan, 1987), and (2) by using a modified scale of seven levels of imposex, developed by Fernandez et al (1998).…”

“…This last effect, denominated imposex is induced in several gastropod species both in the field and in laboratory studies at very low concentrations of TBT (imposex is initiated at less than 1ng/L -1 TBT in Nucella lapilus, and at 3-5ng/L -1 all females may be sterilized (Gibbs & Bryan, 1994; concentrations of 1ng/L -1 can induce imposex development in Thais clavigera, Horiguchi et al, 1995). This widely observed effects suggests that TBT and TPT may also act as endocrinal disruptors (Horiguchi et al, 1995(Horiguchi et al, , 1997aLiu & Suen, 1996;Mathiessen & Gibbs, 1998;Oehlmann et al, 1996).…”

Occurrence of imposex in Thais haemastoma: possible evidence of environmental contamination derived from organotin compounds in Rio de Janeiro and Fortaleza, Brazil

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. The most striking effect of TBT and TPT as hormonal disruptors is the development of male organs in females of gastropods, currently denominated imposex. This syndrome can lead to the sterilization and death of affected organisms. The present work gives an overview of the present state of knowledge on imposex occurrence and reports results of a survey conducted in Guanabara Bay, Rio de Janeiro and in several sites along the coast of Fortaleza, Ceará State. Different stages of imposex development were verified in this survey, however, the most prominent levels appeared associated to known spot sources of TBT and TPT.

The TBT related sex ratio alternation has been reported in T. clavigera (Tan, 1997;Blackmore, 2000;Shim et al, 2000;Li, 2003) and other gastropods, such as N. lapillus , T. biserialis (Ramasamy and Murugan, 2002), Ocinehrina aciculate (Oehlmann et al, 1996b). The affected population may suffer from reproductive failure and even local extinction (Gibbs and Bryan, 1996;Evans et al, 1996).…”

“…The affected population may suffer from reproductive failure and even local extinction (Gibbs and Bryan, 1996;Evans et al, 1996). This phenomenon has been suggested to be caused by selective mortality on female Tan, 1997;Nicholson and Evans, 1997) or sex change of female to male (Oehlmann et al, 1996b;Rilov et al, 2000). Functional sex change of gastropod induced by organotins, however, has not been directly demonstrated at any developmental stage.…”

As active ingredients of anti-fouling paints that are widely used on ship hulls, organotin compounds, in particular tributyltin (TBT), are well-known endocrine disruptors causing sex changes in marine organisms and widespread in coastal waters and sediments worldwide. In this study, a comprehensive ecological risk assessment (ERA) of organotins was conducted in Hong Kong waters through determining the imposex status, sex ratio and tissue burdens of these compounds in the neogastropods, Thais clavigera and Thais luteostoma collected from 29 coastal sites. We also investigated the historical trend of organotin effects on these gastropods, and performed a probabilistic ERA based on tissue burden of TBT in the animals. Our results demonstrated that imposex indices were positively correlated with the body burden of organotins in the gastropods. Across all sites, the sex ratio (female:male) decreased significantly with increasing imposex levels or tissue burden of organotins, implying that such pollutants can result in a male-biased population, potentially leading to local extinction in extreme cases. Based on the ERA, 5.4% of all populations of T. clavigera are at risk due to exposure to TBT; the risks include growth inhibition, impairment of immune functions and reduced fitness. Seriously impacted areas included Aberdeen, Repulse Bay, Butterfly Beach, Mui Wo and Ha Mei Wan. A comparison with historical data revealed that there had been some improvement in the areas with low marine traffic, and distant from the major harbour/port. This could partly be due to the restriction on the use of TBT on small vessels (<25 m in length) since 1992. Nevertheless, the organotin contamination still remains severe in areas with high marine traffic or adjacent to large harbours/ports. In particular, the situation in the northeastern waters of Hong Kong has been getting worst since 1996 that is probably associated with the rapid development of the cargo container port at Yantian in China.

O ermitão Clibanarius vittatus é um organismo típico de regiões intertidais estuarinas sendo considerado um possível bioindicador da presença de tributilestanho (TBT) nesses ambientes. Por esta razão, este estudo apresenta o desempenho analítico e a validação do método para quantificação de TBT em tecidos de C. vittatus por cromatografia gasosa com detector fotométrico de chama pulsante (GC-PFPD), após extração com solvente apolar (tolueno) e derivatização com reagente de Grignard. Os limites de detecção do método (LOD) foram 2,0 e 2,8 ng g -1 para TBT e DBT (dibutil estanho), respectivamente, e seus limites de quantificação (LOQ) 6,6 e 8,9 ng g -1 para TBT e DBT, respectivamente. O método foi aplicado em amostras do Estuário de Santos, Estado de São Paulo, Brasil. As concentrações de TBT e DBT variaram de 26,7-175,0 ng g -1 a 46,2-156,0 ng g -1 , respectivamente. As concentrações encontradas saopreocupantes uma vez que efeitos tóxicos (tais como a alteração endócrina) têm sido relatados em outros organismos, mesmo em níveis inferiores aos registrados no presente estudo.The hermit crab Clibanarius vittatus is a typical organism from intertidal regions being considered as a good bioindicator of tributyltin presence at these environments. Thus this study presents the analytical performance and validation method for TBT quantification in tissues of C. vittatus by gas chromatography with pulsed flame photometric detector (GC-PFPD) after extraction with an apolar solvent (toluene) and Grignard derivatization. The limits of detection of the method (LOD) were 2.0 and 2.8 ng g -1 for TBT and DBT (dibutyltin), respectively, and its limits of quantification (LOQ) were 6.6 and 8.9 ng g -1 for TBT and DBT, respectively. The method was applied to samples from Santos Estuary, São Paulo State, Brazil. TBT and DBT concentrations ranged from 26.7 to 175.0 ng g -1 and from 46.2 to 156.0 ng g -1 , respectively. These concentrations are worrisome since toxic effects (such as endocrine disruption) have been reported for other organisms even under lower levels of registred at this study.Keywords: crustaceans, organotin, tributyltin (TBT), gas chromatography IntroductionButyltin compounds (BTs), members of the class of organometallic contaminants, are found in coastal regions worldwide because they were used in antifouling paints for many years. [1][2][3] In spite of the total worldwide ban proposed by the International Maritime Organization (IMO) in January 2008, these compounds are still found in different environmental compartments of aquatic systems. 4 Their toxic effects are observed in many species because tributyltin (TBT) can induce an endocrine disruption process known as imposex. 5 This effect in mollusks has been well documented.
