“…Another survey on the BTs contamination in seafood from selected cites along Bohai Sea by Zhou et al (2001) revealed that the TBT ranged from b6.9 to 17,175 ng Sn/g on wet weight basis and Dalian was the most seriously polluted area by TBT. When compared the present results with other coastal sites worldwide, it was found that BTs levels in Bohai coast are similar to those in developing Asian countries such as Korea (Hong et al, 2002), Philippines (Prudente, 1999) and Thailand (Kan-atireklap et al, 1998), but higher than those in some TBT antifouling paints-banned countries such as USA (Uhler et al, 1993), Austria (Hong et al, 2002), Canada (Chau et al, 1997) and Japan (Harino et al, 1998). So the BTs contamination in Bohai Sea is rather severe and urgent control or management should be reacted as soon as possible.…”

Thirteen areas around the Chinese Bohai coast, individuals including ten kinds of bivalves and two kinds of snails were collected during the period of 2002-2005 for the investigation of spatial distribution and temporal variations of butyltin compounds (BTs). BTs including tributyltin (TBT) and its derivates, dibutyltin (DBT) and monobutyltin (MBT) were quantified by gas chromatography/flame photometric detection after extraction and Grignard derivatization. BTs compounds were widely existed in the samples and TBT was the dominant composition, indicating recent TBT input along Bohai coast. As a whole, BTs concentration remained high during the sampling years except a slightly decreased in samples from several sites in 2005. The contamination characteristics of BTs in different sampling sites were analyzed using principal component analysis (PCA) method, and the species specific bioaccumulation of BTs was also identified using cluster analysis.

“…Among Asian developing countries considered, BTs levels in mussels from the coastal waters of Korea, China, Philippines and Thailand were in the higher range compared with those from India, Malaysia and Hong Kong. It should be noted that the demand for TBT-based marine coating paints in these countries is currently increasing (Hong, Takahashi, Min, & Tanabe, 2002). In addition, because of the unregulated application of BTs in many Asian developing countries such as China, India, Thailand and the Philippines, as well as other nearby developing countries, BTs contamination in the Asian aquatic environment may become increasingly serious in future.…”

Concentrations of butyltin compounds including tributyltin (TBT), dibutyltin (DBT) and monobutyltin (MBT) were determined in mollusc samples from Chinese Bohai coastal sites to evaluate the extent of contamination and potential adverse effects on health. Wide existence of butyltins was found in these samples with a detection rate of up to 90%, and the concentrations of the total butyltin ( P BTs: TBT + DBT + MBT) ranged from <2.5 to 397.6 ng Sn/g wet weight (mean 63 ng Sn/g). Among BTs, TBT was the predominant compound in most of the samples, indicating ongoing usage of TBT-based antifouling agents in China. The different accumulation capabilities of BTs among various species were studied. The wide occurrence and serious pollution of BTs in seafood indicated a potential danger for the health of the local people who cared for these foods.

“…According to the monitoring results from countries such as France, UK, U.S.A., and Japan, TBT concentrations in seawater have been declining, but they still exceeded the no effect level for the most sensitive species (Dowson et al 1993;1994;Horiguchi et al 1994;Ritsema 1994). Although some studies have reported TBT contamination before the implementation of the regulations (Choi et al 2002a, b;Hong et al 2002;Shim et al 2005), little is known about the effectiveness of the regulations in reducing TBT concentrations in Korean coastal environments. This study was conducted as part of a nationwide survey of persistent organic pollutants in the coastal marine environment of Korea.…”

Tributyltin (TBT) concentrations were determined in seawater, sediments and bivalve samples collected from Korean coastal areas during 2001-2005, to investigate the levels and temporal variation in TBT contamination in relation to the timing of the imposition of regulations on TBT use in Korea. TBT concentrations ranged from <5.0 to 164 ng/L in seawater, from <7.0 to 9,576 ng/g dry weight in sediments, and from <7.0 to 6,296 ng/g dry weight in bivalves. The highest concentrations of TBT were found at locations close to intensive shipping traffic and industrial complexes, and the contamination at some hot spot areas was high enough to cause harmful effects on marine organisms. TBT concentrations and their occurrence in Korean coastal waters have been decreasing annually. In particular, TBT concentrations in seawater have dramatically decreased. This result is consistent with regulations and bans on the use of TBT in Korea.
