“…A wide range of butylins suggests localized areas of contamination and the present TB values are consistent but lower than those reported earlier (Bhosle et al 2004). Rajendran et al (2001) reported TB values ranging from 5 to 58 ng l -1 from Tuticorin harbour along the east coast of India.…”

“…Although triphenyltins (TPhT) are used in antifouling paints, their major application is in agriculture as a pesticides, insecticides, fungicides etc (Bortoli et al 2003;Bhosle et al 2004;. These antifouling compounds enter into the marine waters through land runoff, and leaching of antifouling paints.…”

“…Moreover, there is very little knowledge about the levels of organotins in marine waters, sediments and organisms collected form coastal environment of India. Little is known about the distribution of organotin compounds in the waters and sediments along the west coast of India (Rajendran et al 2001;Bhosle et al 2004;. The Mandovi and Zuari estuary are located on the west coast of India, and are used for navigation of recreational boats and fishing vessels, and for the transport of iron and manganese ores from the hinterland to the Marmugoa harbour.…”

Butyltins (TBT, DBT, MBT) were measured in water and sediment samples collected from various locations in the Mandovi (10 stations) and Zuari (9 stations) estuaries during November 2007. The total butyltin (TB) in water samples varied between ~12 and 73 and from 0.5 to 77 ng Sn l -1 ; whereas, for the sediments it varied from ~ 15 to 118 and 6 to 119 ng Sn g -1 dw for the Mandovi and the Zuari estuaries, respectively. The average TB concentration in the sediments from the Zuari estuary was higher as compared to the Mandovi estuary, whereas for the water samples it was vice versa. For both the water and sediment samples, MBT was generally the most predominant butyltin in these two estuaries. This suggests that the butyltins contamination was not freshly derived. Fairly good relationships between the concentrations of TB and organic carbon in water and sediment samples of these estuaries implicate the importance of adsorption/desorption processes in controlling the levels of TB in these estuaries.

“…The presence, fate and long-term behavior of TBT and other butyltin compounds in sediments is an issue of concern worldwide (Bhosle et al, 2004;Sudaryanto et al, 2004) with occurrence of imposex continuing to be reported (Fernandez et al, 2005). The importance of generating further data on TBT for use in developing models for understanding the mass balance of priority contaminants within water bodies of has recently been highlighted by studies focused on the Great…”

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.

“…We tested concentrations from 10 −4 M (29.1 mg L −1 TBT and 11.87 mg L −1 Sn) to 10 −12 M (0.291 ng L −1 TBT and 0.118 ng L −1 Sn), which are environmentally realistic. Since the ban of the use of TBT in antifouling paints, 100 ng L −1 of TBT (expressed as Sn), which corresponds to a concentration of about 10 −9 M, has been measured in the water column (Bhosle et al 2004;AntizarLadislao 2008).…”

-European Community regulations on chemicals promote alternative methods to test substances presenting potential risks for the environment. In the present work, cultured atrial cells isolated from oyster (Crassostrea gigas) were used as an experimental model to investigate the toxicity of tributyltin (TBT) after short-time exposure at concentrations representative of those that can be measured in seawater, marine sediments and/or bivalves bioaccumulating this pollutant. In vitro and in vivo assays produce values of the same order of magnitude for both animal/cell survival and heart/cardiomyocyte beating rate. The survival rate of whole animals decreased from 10 −6 M TBT after 3 days. For cultured cells, the viability, evaluated using 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay, significantly decreased after two days of treatment with 10 −6 M TBT, and after six days with 10 −10 M TBT. The percentage of apoptotic cells, quantified by flow cytometry and YO-PRO r -1 iodide, a nucleic acid stain that only permeates cells that are beginning to undergo apoptosis, increased significantly in these cases. Moreover, intracellular concentration of Ca ++ had increased after 10 min of exposition to 10 −6 M, and could be associated with apoptotic processes. As patch clamp experiments showed that Ca ++ conductance was decreased, intracellular calcium increase could mainly be due to a release from internal stores. The decreases in beating rhythm could be explained by the decrease in adenosine triphosphate (ATP) production revealed by 31 P nuclear magnetic resonance (NMR) spectroscopy and confirmed by the increase of the K ATP channel conductance. The related hyperpolarization and the disturbances of the energetic metabolism were clearly related to the loss of the atrial cell contractility and viability.
