由于有机锡化合物对生物体的有害作用，其广泛使用所造成的水环境污染已引起人们的极大关注。然而，尚未对深海生态系统中的有机锡污染进行研究。本研究试图确定丁基锡化合物（BTs），包括一（MBT），二（DBT），和三丁基锡（TBT）在深海生物收集骏河湾，日本，以阐明污染状况和积累特性。在135和980米之间的无光半深海带的生物收集，并与那些从浅沃茨收集的比较。总丁基锡（TBT：在深海鱼类、甲壳类动物、头足类动物、棘皮动物和腹足类动物的组织中，甲基丁基锡化合物（MBT + DBT + TBT）的浓度分别高达980、460、460、130和21纳克/克（湿重）。这些水平低于同一海湾的浅水生物，但与东京湾等工业化地区报告的水平相当，表明BT污染在深海生态系统中的扩展。骏河湾的深海生物所含的生物技术含量远远高于先前报告的有机氯浓度。BT蓄积似乎具有较低的脂质依赖性。在生物技术中，三丁基锡化合物是除头足类以外的主要化合物，这表明三丁基锡化合物是新近进入深海环境的。据我们所知，这是关于检测深海生物体内有机锡残留物的第一份报告。
Aquatic pollution resulting from extensive usage of organotin compounds has been of great concern due to their deleterious effects in organisms. However, organotin contamination in deep-sea ecosystems has not yet been studied. The present study was attempted to determine butyltin compounds (BTs), including mono- (MBT), di- (DBT), and tributyltin (TBT) in deep-sea organisms collected from Suruga Bay, Japan, in order to elucidate the contamination status and accumulation characteristics. The organisms were collected between 135 and 980 m in the aphotic bathyal zone and compared with those collected from shallow waters. Total butyltin (ΣBT: MBT + DBT + TBT) concentrations in the tissues of deep-sea fish, crustaceans, cephalopods, echinoderms, and gastropods were up to 980, 460, 460, 130, and 21 ng/g wet wt, respectively. These levels were lowerthan those in shallow-water organisms from the same bay but comparable to those reported in industrialized areas like Tokyo Bay, suggesting the expansion of BT pollution in deep-sea ecosystems. Deep-sea organisms from Suruga Bay contained much higher levels of BTs than previously reported organochlorine concentrations. BT accumulation appeared to be less lipid dependent. Among BTs, TBT was the predominant compound except in cephalopods, suggesting a fresh input of TBT into the deep-sea environment. To our knowledge, this is the first report on the detection of organotin residues in deep-sea organisms.
