“…are similar to concentrations reported for bivalves and gastropods from contaminated sites, but higher than concentrations reported in fish, macroinvertebrates and macrophytes (Fent, 1996;Bouma et al, 2000;Birchenough et al, 2002). Only one report was found in literature on organotin concentrations in mysids of the Haihe estuary in China and total butyltin concentrations were 720 ng/g dw, which is in the same order of magnitude as concentrations reported in our study (Sun et al, 2001).…”

Abstract. Sediment and mysids from the Scheldt estuary, one of the largest and most polluted estuaries in Western Europe, were analyzed for a number of contaminants that have shown to possess endocrine-disrupting activity, i.e. organotins, polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), tetrabromobisphenol A (TBBPA), nonylphenol ethoxylates (NPE) and transformation products nonylphenol (NP) and nonylphenol ether carboxylates (NPEC). In addition, in vitro estrogenic and androgenic potencies of water and sediment extracts were determined. Total organotin concentrations ranged from 84 to 348 ng/g dw in sediment and 1110 to 1370 ng/g dw in mysid. Total PBDE (excluding BDE-209) concentrations ranged from 14 to 22 ng/g dw in sediment and from 1765 to 2962 ng/g lipid in mysid. High concentrations of BDE-209 (240-1650 ng/g dw) were detected in sediment and mysid (269-600 ng/g lipid). Total HBCD concentrations in sediment and mysid were 14-71 ng/g dw and 562-727 ng/g lipid, respectively. Total NPE concentrations in sediment were 1422 ng/g dw, 1222 ng/g dw for NP and 80 ng/g dw for NPEC and ranged from 430 to 1119 ng/g dw for total NPE and from 206 to 435 ng/g dw for NP in mysid. Significant estrogenic potency, as analyzed using the yeast estrogen assay, was detected in sediment and water samples from the Scheldt estuary, but no androgenic activity was found. This study is the first to report high levels of endocrine disruptors in estuarine mysids.Capsule. Field populations of mysid shrimp (Neomysis integer) of the Scheldt estuary (The Netherlands) are exposed to high concentrations of endocrine disruptors.

“…In 1997, Michel & Averty (1999) measured a maximal value of 37.4 ng l -1 in Brest Harbour, and described a general decrease in TBT concentrations in French seawaters compared to 1992 conditions. Similar improvements of imposex condition have been reported in other areas where legislative bans of TBT were effective, such as in the North Sea (Evans et al 1991, 1996, Harding et al 1997, Birchenough et al 2002a), SW England (Bryan et al 1993), Ireland (Minchin et al 1995), Australia (Rees et al 2001) and Canada (Reitsema et al 2002). Despite the same legislative ban of TBT, a reverse trend has been observed in Spain (Ruiz et al 1998, Ramon & Amor 2001 and in Portugal (Barroso & Moreira 2002, Santos et al 2002.…”

Tributyltin (TBT) pollution has been assessed in NW Brittany since 1992 using the bioindicator imposex in Nucella lapillus. The Bay of Brest is highly polluted by TBT and the outgoing water mass has contaminated the adjacent NW coasts. However environmental conditions have been improving in NW Brittany. The decrease in TBT pollution is most likely due to the reformulated antifouling paints (with slower leaching rates or TBT-free) that are used for civil and military careening activities in the Bay of Brest. An increase in imposex levels in 1998 could have been due to the launching of the aircraft carrier 'Charles de Gaulle'. It remains unknown when imposex levels reached their maximum because of the lack of annual surveys in 1996, 1997 and 1999. This underscores the need for annual surveys when using imposex as a monitoring tool.

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.
