“…The certified value of MBT for sediment PACS 2 has been shown to be debatable by a number of independent publications. The actual MBT concentration appears to be closer to 600 ng Sn g −1 (Scrimshaw et al 2005).…”

Tributyltin and its degradation products, mono-and dibutyltin have been determined in sediments collected in some representative sites in San Vicente Bay, Chile. The organic matter contents of sediments and water collected simultaneously from the same sampling sites were also determined. High levels of total organic carbon were found in sediments, especially in those from the northern part of the bay (1.80-8.87%). Good correlations were found between total organic carbon and the oxidizable and refractory carbon fractions. Among the butyltin species determined, TBT presented the highest levels, ranging from 14 to 1,560 ng Sn g(-1) dry weight. Concentration ratios of TBT to DBT ranged between 1.33 and 3.10, showing a high degree of contamination in sediments of this Chilean bay. All data obtained were analysed by the chemometric method of principal components analysis. A strong correlation was found between TBT and DBT concentrations in sediments, the different organic matter contents in sediments and water. In marine organisms only TBT was detected, containing the filterer organism Semele solida higher level than Perumytilus purpuratus and Pyura chilensis (220, 150 and 120 ng Sn g(-1) dry weight, respectively). For the alga Rodoficea iridae the TBT concentration was 60 ng Sn g(-1) dw. Comparatively, these values are higher than those reported for the same kind of marine organisms worldwide. The different samples from San Vicente Bay were found to be contaminated by TBT. This contamination can be attributed to the different anthropogenic activities taking place in the bay.

“…Phenyltin concentrations are lower, between 0.5 and 49 ng Sn g −1 for MPhT, 0.2 and 8 ng Sn g −1 for DPhT, and 0.1 and 0.5 ng Sn g −1 for TPhT, while octyltins concentrations were lower than 0.5 ng Sn g −1 . Scrimshaw et al (2005) investigated the historical deposition of butyltins in bed sediments from the harbor in the River Thames (UK). Results from sediment cores demonstrated that in most samples, TBT concentrations of 20-60 ng Sn g −1 accounted for less than 10% of the total butyltin species present.…”

“…Trisubstituted OTC, including TBT and TPhT, are among the most hazardous pollutants to enter aquatic ecosystems (Hoch 2001 EC 2000). Although OTC were intensively investigated in the marine environment (Coelho et al 2002;Díez et al 2005;Godoi et al 2003;Gomez-Ariza et al 2001;Harino et al 1999;Milivojevič Nemanič et al 2002Ščančar et al 2007), they are a rare subject of research in river sediments (Bancon-Montigny et al 2004;ICPDR 2002;Lacorte et al 2006;Scrimshaw et al 2005).…”

Sediment pollution of the biggest Danube tributary, the Sava River, was investigated within the sixth framework European Union project "Sava River Basin: Sustainable Use, Management and Protection of Resources" (SARIB). The extent of pollution was estimated by determining the amount of inorganic and persistent organic pollutants in sediment samples at 20 selected sampling sites along the Sava River. For the purpose of clarity, the findings are presented and published separately (part I: selected elements and part II: persistent organic pollutants). This study presents an investigation into the presence of organic pollutants in the Sava River sediment. According to the Water Framework Directive, the following persistent organic pollutants were investigated: polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), selected chlorinated pesticides and organotin compounds. The results reveal that PAHs were present in moderate concentrations (sum of 16 PAHs: up to 4,000 ng g(-1)) and their concentrations increased downstream. Concentrations of PCB were low (sum of seven indicator PCBs: below 4 ng g(-1)) and among the pesticides analyzed only p,p-dichlorodiphenyltrichloroethane was found in moderate concentrations at two sampling sites in Croatia (up to 3 ng g(-1)) and hexachlorobenzene was found in a high concentration in the city of Belgrade (91 ng g(-1)), although the use of these persistent pesticides has been banned for decades. Repeated sampling at the same location revealed point pollution near Belgrade. Among the organic pollutants surveyed, organotin compounds were not detected. Overall results reveal the presence of persistent organic pollutants in 20 of the Sava River sediments tested that is, in general, comparable or lower than the levels in the Danube River and other moderately polluted European rivers.

“…Other areas of the Iberian Peninsula also show similar values as studied by Quevauviller et al (1989) in the Sado Estuarine System, western Portugal (TBT: 12-520 ng Sn g -1 dw) and by Gabrielides et al (1990) (TBT: 35-975 ng Sn g -1 dw) and Tolosa et al (1992) (TBT: 9260 ng Sn g -1 dw) in the Mediterranean region. The study of the levels of TBT in other European countries shows different values amongst locations: Chiavarini et al (2003) in the North West Sicilian coast in Italy (TBT: 3-27 ng Sn g -1 dw), Jacobsen (2000) in Danish harbours and marinas (TBT: 100-5,000 ng Sn g -1 dw) and Scrimshaw et al (2005) in the river Thames in United Kingdom (TBT: 1-60 ng Sn g -1 dw). In comparison with the ecosystems reported by these authors, the butyltin levels in the sediments along the Gulf of Cádiz suggest a relatively low contamination in general.…”

Surface sediment samples were analyzed for organotins namely tributyltin (TBT), dibutyltin and monobutyltin from six areas located in the Gulf of Cádiz (14 stations), Spain. The total butyltin ranged between undetected and 1,580 ng Sn g(-1). TBT generally prevailed in most of the samples, suggesting fresh inputs of butyltin compounds and/or less degradation of TBT. The observed levels of butyltins at several sites are much higher than that required to induce toxic effect on marine organisms, suggesting that these sediments are polluted with butyltin compounds. The clam Ruditapes philippinarum was used for studying bioaccumulation of butyltins by exposing them to contaminated sediments from the Gulf of Cádiz over a period of 28 days under laboratory conditions. Biota-sediment accumulation factor (BSAF) ranged from 0.44 to 3.99.
