“…These observations are consistent with the broad mode of action of MEMC. The effects on adult corals are similar to those of the antifoulant TBT, which can cause both tissue damage and a slight reduction in photosynthesis at low concentrations (Smith et al 2003).…”

“…The wide range of organisms, bacteria included, affected by the toxic effects of TBT (White et al, 1999;Alzieu, 2000;Petersen and Gustavson, 2000;Qun-Fang et al, 2002;Smith et al, 2003;Jensen et al, 2004;White and Tobin, 2004) suggests that molecular cell components common to all living systems, namely biomembranes, may constitute the main target of this lipophilic xenobiotic. Prokaryotic cells are particularly useful to study the molecular toxicity of membraneactive compounds, offering advantage over eukaryotic cells owing to the simple membrane organization.…”

“…Reports of TBT toxicity to organisms belonging to the five taxonomic kingdoms have been reported (White et al, 1999;White and Tobin, 2004;Smith et al, 2003;Jensen et al, 2004), endocrine disruption, (Schulte-Oehlmann et al, 1997) and mitochondria function impairment (Jurkiewicz et al, 2004) effects. However, the molecular mechanisms underlying the toxicity of TBT are far from full understanding.…”

Tributyltin is a potent biocide mainly used in marine antifouling paints. Owing to its widespread distribution in coast areas and its high toxicity to aquatic organisms, the use of this compound is generally restricted and under government regulation. Despite of that, it persists in the aquatic environment. Organotins used in industry have also been detected in terrestrial environments. The persistence and high lipophilicity explain bioaccumulation. The role of bacteria in recycling organic matter prompted us to study the interaction of tributyltin with two ubiquitous bacilli, B. stearothermophilus and B. subtilis, proposed as biological indicators of pollutants with ecological impact. These bacteria have been used as suitable models for the study of toxicity mechanisms of unselective lipophilic compounds (e.g., DDT and endosulfan). Drug effects on growth parameters, oxygen consumption and membrane organization were assessed. Bacteria growth in a liquid complex medium was disturbed by concentrations of TBT as low as 25 nM (8 lg L À1 ), close to the concentration in polluted environments. The respiratory activity is affected by TBT in both microorganisms. Membrane organization, assessed by fluorescence polarization of two fluidity probes, 1,6-diphenyl-1,3,5-hexatriene (DPH) and a propionic acid derivative (DPH-PA), was also perturbed by the xenobiotic. Alterations on growth, oxygen consumption and physical properties of membrane lipids are stronger in B. stearothermophilus as compared to B. subtilis. A putative relationship between growth inhibition and respiratory activity impairment induced by TBT and its effects on the physical behaviour of bacterial membrane lipids is suggested.

“…The chronic toxicity of TBT to biota and the relationship between toxicity and bioaccumulation has been identified as a tool for predicting the toxicity of contaminated sediments (Bartlett et al, 2004) and the availability of sediment bound TBT to biota, as demonstrated by uptake and effects, is supported by other studies (Midorikawa et al, 2004;Ramaswamy et al, 2004). Contamination with TBT may effect a range of organisms, and although effects on molluscs are well documented, corals have also been identified as being impacted by TBT (Smith et al, 2003) indicating that understanding the fate and behavior of residues of TBT is likely to be significant in protecting a wide range of ecosystems.…”

Sections from a sediment core taken from the River Thames were analysed for butyl tin species using gas chromatography with species-specific isotope dilution mass spectrometry. Results demonstrated that in most samples tributyltin concentrations of 20 -60 ng/g accounted for <10% of the total butyl tin species present, which is in agreement with data from other sediment samples which were historically contaminated with tributyltin. Vertical distribution of the organotin residues with depth throughout the core, with data on organochlorine compounds and heavy metals allowed for the construction of a consistent hypothesis on historical deposition of contaminated sediments. From this it was possible to infer that the concentrations of tributyltin in sediments deposited during the early 1960s were in the order of 400 -600 μg/g by using degradation rate constants derived by other workers. Such values fall well within the range quoted for harbour sediments in the literature.
