“…from the northern part of Vietnam, who reported partition coefficients in the range of 0.5-5.5, with a mean of 2.01. These values are also greater than the range 4-7 reported by Hwang et al (1999) for the filtering species Crassostrea gigas and Mitylus edulis galloprovinciallis. These results indicate that over time, sediments appear to act as secondary sources of contamination for these organisms, either because TBT adsorbed previously may be desorbed or re-suspended into the water column and become available again or because TBT ingested with food is assimilated.…”

“…It can be observed that these concentrations are variable depending on their location. It is also possible to deduce that the TBT levels in the filtering organisms and in the alga from San Vicente bay are higher than those summarized in Table 6, with the exception of those reported by Hwang et al (1999) for the species C. gigas and M. edulys galloprovinciallis from Korea.…”

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.

“…Degradation of TBT in the water column occurs on the order of days or weeks, but degradation happens more slowly (on the order of years) in sediments, where TBT is strongly adsorbed and may be present in high concentrations (Stang & Seligman 1987, Hwang et al 1999. However, slow release of TBT from contaminated bottom sediments remains a potential longterm source of recontamination.…”

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.

“…Presence of organotin compounds in Chinhae Bay sediments and organisms has been reported [3][4][5] . A preliminary study conducted in 1995 6 indicated that toxic organic contaminants such as PCBs, chlorinated pesticides, PAHs, and organotin compounds were present in the marine sediments and molluscan tissues.…”

Persistent organic pollutants (POPs) were monitored in surface sediment of Chinhae Bay, Korea. Sum (») concentration (minimum, maximum and averageng/g dry weight) ranged: »BTs (ng Sn/g): 12, 1230, 221; »PAHs: 54, 632, 182; nonylphenol: 107, 207, 148; bisphenol A: 4.36, 135, 83; T-PCBs: 0.64, 18, 3.49; »DDT: 0.19, 7.36, 1.15; »CHL: 0, 0.49, 0.06; »HCH: 0.03, 0.36, 0.10. Among them BTs, PAHs, nonylphenol and bisphenol A were detected in all locations. Chlordanes, HCHs and DDTs were at low levels. Levels of tributyltin remained similar to levels in 1987-94. PAHs were within national average. Chinhae Bay derives its pollution from a) two possible point sources, namely, industrial and urban activities from inner Masan Bay and shipping activities from Kohyon Bay; b) diffuse sources of various sorts. Spatial distribution and chemical composition of POPs together with their inter-relationships were investigated.
