“…If BMF > 1, then the equilibrium whole-body-averaged concentration of the chemical will be higher in the predator than in its food. To calculate the BMF of TBT and MeHg for the American plaice, we used our experimental data (Table 1) and values of k, for MeHg in flatfish given by Jarvenpaa et al (1970) and Pentreath (1976) which comprised between 0.001 and 0.004 d-l. BA4Fcalculated this way ranges from 0.1 to 0.5 for TBT and from 2 to 9 for MeHg, values similar to those previously reported from the ratio of organometal concentration in various marine fish species over that measured in their food (Francesconi & Lenanton 1992, Takahashi et al 1997.…”

“…The fact that TBT is readily metabolised in organisms like fish and crustaceans suggests that the long-term biomagnification of TBT is not as significant as for MeHg and organochIorine pollutants (Fent 1996). However, recent monitoring results showed that TBT may be biomagnified by various marine organisms (Takahashi et al 1997, and references therein), indicating that the trophic transfer of this organometal needs to be investigated in more detail.…”

ABSTRACT-Pharmacokinetics and distribution of a 5 pg dietary dose of tributyltin (ll3Sn-TBT) and methylmercury [Me2":'Hg) were studied over 4 2 d in the American plaice Hjppoglossoides platessoides, using in vivo gamma counting, whole-body autoradiography, and a 2-compartment model. The average retention efficiency of TBT was 42'!~,, compared with 88"; for Mcl-lg. Both organometals were distributed to the entire body of the fish. Distribution proceeded at a faster rate for TBT. 95'1; of the stcady state distribution being reached within 5 to 10 d. compared with 29 to 41 d for MeHg. Elimination of TBT was characterised by half-life values ranging from 15 to 77 d. Absorption of dietary TBT from the intestinal lumen appears to be limited by ~t s molecular size, whereas its fast translocatlon rate in the body of fish might be related to specific properties of the intestinal epithelium-blood interface or to cotransport with lipids. Our data also indicated that butyltins in the viscera were partitioned between 2 kinetically distinct pools; one that was eliminated rapidly and one that was stored or eliminated at a very slow rate, probably as a consequence of TBT metabolism. The overall biomagnification factor for the transfer of TBT from sediments to benthic invertebrates to the American plaice may be > l . This indicates that the trophic transfer of sedimentary TBT in the manne benthic food web is potentially significant.

A B S T R A C TMarine organisms are affected by organotin compounds due to the cumulative, deleterious effects of these latter. The most evident and well known consequence of organotin contamination is imposex, a hormonal disruption that causes a superimposition of sexual male features in females of prosobranchia neogastropod molluscs such as Stramonita haemastoma floridana. Molluscs accumulate organotins mainly because of their poor ability to eliminate TBT and DBT from their tissues. The aim of this study was to analyze organotin uptake by ingestion experimentally, using uncontaminated subjects (S. haemastoma floridana) fed with organotin-contaminated oysters (Crassostrea rhizophorae). A total of 248 gastropods, distributed in 7 tanks with uncontaminated water and contaminated food, were used in this study, a control group being fed uncontaminated oysters. Every 15 days, the individuals of one of the tanks were examined for the presence of imposex. Development of imposex was measured using the VDSI, RPSI and RPLI indexes. The animals had already developed imposex within the first 15 days, all the indexes measured (RPLI, RPSI and VDSI) having increased significantly with duration of exposure, indicating that the animals were probably contaminated by the food and had accumulated the pollutant. New paths of imposex development were also observed. R E S U M OOrganismos marinhos são afetados por compostos organoestânicos que causam uma série de efeitos deletérios aos mesmos. O mais conhecido efeito da contaminação por organoestânicos é o imposex. Esse fenômeno consiste na masculinização de fêmeas de moluscos neogastrópodes tais como Stramonita haemastoma floridana. Esses compostos tendem a se acumular em moluscos devido a sua baixa capacidade de eliminá-los. Um total de 248 indivíduos de S. haemastoma floridana foram coletados de uma população livre qualquer indício de imposex. Esses animais foram mantidos em 7 aquários, com aproximadamente 30 indivíduos cada, 1 desses aquários foi considerado como controle e os animas do mesmo alimentados com ostras obtidas de locais onde não se verificou a ocorrência de imposex em neogastrópodes nativos. Os animais nos outros 6 aquários foram alimentados com ostras obtidas em local onde a incidência de imposex entre os gastrópodes nativos revelou-se muito alta. A cada 15 dias, por um período total de 90 dias, os animais de um dos tanques eram retirados e analisados quanto à presença de imposex. Os níveis de imposex foram quantificados através da % de imposex e dos índices: RPLI, RPSI e VDSI. Observou-se a indução de imposex em S. haemastoma floridana através da dieta a partir de Crassostrea rhizophora e um aumento significativo dos índices com o decorrer do tempo de exposição. Os animais do aquário controle foram analisados ao fim do experimento não revelando qualquer indício de imposex.

Concentrations of tributyltin (TBT) and its degradation products, monobutyltin (MBT) and dibutyltin (DBT), were determined in the liver and kidney of striped dolphins ( Stenella coeruleoalba), bottlenose dolphins ( Tursiops truncatus) and in a fetus of the common dolphin (Delphinus delphi) found stranded along the western Italian and Greek coasts in the period 1992–1994. Butyltin (BT) compounds were detected in almost all the samples analyzed and were higher in the kidney than in the liver. Total BT concentrations were 0.78–8.05 μg g−1 wet wt in kidney and 0.015–1.02 μg g−1 wet wt in liver of S. coeruloealba. Bottlenose dolphins had lower BT concentrations than striped dolphins. Although only one fetal sample was analyzed, it showed the highest BT concentrations of all. Unlike BT concentrations in the other adult dolphins, in the pregnant dolphin they were higher in the liver (4.35 μg g−1 wet wt), suggesting that BTs are transferred from mother to fetus. No significant differences in BT concentrations were found between sexes. Of the breakdown products, DBT was predominant in most liver samples and MBT was more abundant in kidney. Although BT concentrations are known to be found in cetaceans inhabiting waters of developed countries, our observations strongly suggest that concentrations found in S. coeruleoalba were either similar to or higher than those reported for other Stenella species collected from coastal areas close to harbors or marinas.
