  • Accumulation of tributyltin (TBT) in serum, liver and muscle of olive flounder (Paralichtys olivaceus) was investigated in a 60-d static renewal exposure at $0.1{\mu}g$ TBT/L. Tributyltin accumulated rapidly from 83 ng Sn/g to 2,227 ng Sn/g on a wet weight basis in the serum of the olive flounder and to a greater extent than in the other tissues. The accumulated TBT concentrations in tissues were in the order of serum>liver>muscle on wet or dry-weight basis. High concentrations of dibutyltin (DBT: 990 ng Sn/g dry wt) and monobutyltin (MBT: 141 ng Sn/g dry wt), degradation products of TBT were found in liver of olive flounder at the end of exposure. On the other hand, DBT and MBT was below the detection limits in muscle during the exposure, and only low concentration of DBT (56 ng Sn/g) were detectefd in serum. Butyltin compounds were also quantitatively determined in feral fine-spotted flounder (Pleuronichthys cornutus) collected from Gwangyang Bay as one of polluted area and Sori Island as a reference site. All three butyltin compounds were detected from the fine-spotted flounder from Gwangyang Bay up to 3,107 ng Sn/g of total butyltins in liver, while 120 ng Sn/g of total butyltin concentration was found in the liver of fish from Sori Island.

  • Butyltin compounds in seawater, sediments and organisms inside Jeju Harbor of Jeju Island, Korea, were quantitatively determined to assess the extent of contamination and to evaluate the bioaccumulation in Thais clavigera (gastropod), Liolophura japonica and Cellana nigrolineata. In addition, imposex in T. clavigera was used to assess the sublethal effect of tributyltin compounds and its usage as a specific biomarker for these compounds was also studied. The main species in seawater was tributyltin (TBT) in March and June, monobutyltin (MBT) in August, but in sediments and organisms it was dibutyltin (DBT) and TBT, respectively, irrespective of survey time. TBT, the most toxic to aquatic organisms among BTs, was found at concentrations which were sufficient to have a serous effect on the sensitive organisms upon chronic exposure. The high correlations (r>0.7) between BTs indicated that DBT and MBT were mainly degraded from TBT based on antifouling paints and their sources were negligible. The sedimentary organic matters have little influence on the distribution of BTs in marine environment and the lipid content in T. clavigera showed a significant correlation with TBT concentrations. Measurement of imposex T. clavigera was expected to be a very helpful tool for preliminary survey of BTs prior to trace analysis of those.

  • Butyltin and phenyltin residues were quantified in seawater and biota of the Chinhae Bay System, Korea in 1995. Butyltin compounds were detected in all seawater and biota samples, whereas phenyltin compounds were found only in the biota samples. Tributyltin (TBT) concentrations in seawater ranged from < 8-35 ng Sn/l. Tributyltin concentrations in Crassostyea gigas and Thais clavigera ranged from 95-885 and 23-414 ng Sn/g, respectively, Triphenyltin(TPhT) concentrations in each species ranged 155-678 and 46-785 ng Sn/g, respectively. Spatial distribution of TBT was closely related to boating and dry-docking activities. However, spatial distribution of TPhT was not consistent with that of TBT. The biological concentration factor for TBT in C. gigas was about 25000 that is four times greater than that of T. clavigera. Butyl- to phenyltin concentration ratio was greater than one in C. gigas, but that in T. clavigera was less than one. Major tissues of C. gigas also showed different accumulation patterns for butyl- and phenyltin compounds. Furthermore, 19 and 28% of total body burdens of TBT and TPhT were found in gonadal mass of C. gigas just prior to spawning.

  • Butyltin compounds (BTs) were determined in surface sediment samples from Ulsan Bay in 2009 and 2011, to assess the contamination status and the effectiveness of tributylin (TBT) restriction of Korea. Dibutyltin and TBT concentrations in sediments in 2011 ranged from 19.5 to 980 and 14.2 to 1204 ng Sn $g^{-1}$ dry weight, respectively. The highest TBT concentration was found in a big shipyard complex and the next highest was found in harbor, suggesting that harbor and shipyard activities are a major contamination source of TBT in Ulsan Bay. Concentrations of BTs in Ulsan Bay sediments were significantly lower in 2009 and 2011 than that in 2003 survey previously reported, probably as a consequence of the legislative action in Korea. However, TBT concentrations in sediments still exceeded ecotoxicological values. Therefore, it will be important to monitor and reduce TBT contamination in sediments until the levels fall well below ecotoxicological levels.

  • 여러 가지 화학물질이나 중금속 등에 의한 생물학적 피해가 오랜 기간에 걸쳐 연구 되어 왔는데, 최근 들어 화학물질 가운데 TBTs, PCBs, DBTs 등이 내분비계 장애물질로 분류되어 여러 가지 환경적인 규제의 대상이 되었다. 이 가운데 TBTs는 살충제로서 개발되어 선박 등의 방오도료에 이용되고 있으며, 이들 물질에 장기간 노출된 수 서생물은 생식 및 생리대사에 영향을 받게된다 (Piver, 1973). (중략)

  • Tributyltn, triphenyltin and their degradation products were quantitatively determined in sediments, seawater, and oysters (Crassostrea gigas) collected from Okpo Bay, Korea where a huge shipyard was located. The concentrations of TBT in sediment and oyster were in the range of 5∼2,050 ng/g and 387∼1,190 ng/g (astin on a dry weight basis), respectively. In seawater, it ranged from 19 to 84 ng/ℓ The distribution of TBT compound showed negative gradient from inner to outer bay, which indicates that the shipyard is the point source of TBT contamination in the bay. The contribution of TBT to butyltin concentration in sediment was above 57%. The pattern of TBT distribution was influenced by waterbreak transected the bay. TPhT concentration in oyster ranged from nd (not detected) to 52 ng Sn/g dry wt., whereas that in sediment and seawater was below detection limit. The biological concentration factor (BCF) in oyster was 1.1×10⁴.

  • Butyltin compounds (BTs) in seawater, sediments and organisms (Thais clavigera, Liolophura japonica and Cellana nigrolineata), were quantitatively determined to evaluate their distribution inside Songsan Harbor of Cheju Island. In addition, imposex in T. clavigera was used to assess the effect on organisms of BTs. Analysis of the samples collected in seawater, sediments (March, June and August) and organisms (May, July and August) in 1998, confirmed the contamination of BTs in the aquatic environment inside Songsan Harbor. The main BTs species in seawater and sediments was monobutyltin (MBT), tributyltin (TBT), respectively, irrespective of survey time. In oranisms, TBT and dibutyltin (DBT) were detected in similar concentrations for T. clavigera and L. japonica, but for C nigrolineata, DBt concentration was the highest. TBT, the most toxic to aquatic organisms among BTs, was found at concentrations which were sufficient to have a serious effect on the sensitive organisms upon chronic exposure, The relatively high correlations (r>0.83) between BTs indicated that DBT and MBT were mainly degraded from TBT based on antifouling paint and their sources were negligible. The sedimentary organic matters did not have influence on the distribution of BTs in marine environment, and lipid content in T. clavigera did not show a correlation with TBT concentrations. The rate of occurrence of imposex in T. clavigera was 100%, and the relative penis length index (RPLI) and the relative penis size index (RPSI) which represent the degree of imposex were 79.7%, 58.1%, respectively. Measurement of imposex in T. clavigera was expected to be a very helpful tool for preliminary survey of BTs prior to trace analysis of BTs.
