对1995年在泰国沿海地区收集的沉积物中丁基锡化合物（bt）进行了分析，包括三丁基锡（TBT）、二丁基锡（DBT）和单丁基锡（MBT）。bt污染在沿海地区广泛存在，地表沉积物中MBT、DBT和TBT的浓度分别为7 - 410、2 - 1900和4 - 4500 ng g - 1（干重基础）。高TBT浓度与大型商业或远海船只区有关，而高渔船和沿海海水养殖区的浓度较低。大型商船和渔船的船体可能是泰国沿海水域BT污染的重要来源。热带地区TBT在沉积物中的降解程度可能高于亚热带地区。据我们所知，这是泰国沉积物中检测到bt的第一份报告。
Butyltin compounds (BTs) including tributyltin (TBT), dibutyltin (DBT) and monobutyltin (MBT) were analysed in sediments collected from coastal areas of Thailand in 1995. Contamination by BTs have been widespread along the coastal areas with concentrations of MBT, DBT and TBT in surface sediments ranging from 7 to 410, 2 to 1900 and 4 to 4500 ng g−1(dry weight basis), respectively. High TBT concentrations were associated with large commercial or far seas vessels areas, while the levels at high fishing boat and coastal mariculture areas were lower. Large commercial ship and fishing boat hulls might be significant sources of BT contamination in Thailand coastal waters. Degradation of TBT in sediments might be higher in tropics than in sub-tropical zone. To our knowledge, this is a first report on the detection of BTs in sediments from Thailand.
