这项研究报告了来自北极、南极、澳大利亚和北美东西海岸的海洋哺乳动物和鸟蛋中三(4-氯苯基)甲醇(TCP甲醇)的水平。除了三个牛奶样品(即一个南极海豹和两个澳大利亚海狮)外，所有被分析的样品中都检测到了三氯甲烷。北极熊(Ursus Maritimus)肝脏中的磷酸三钙甲醇含量最高，几何平均值为5200-mu-g/kg(以脂肪重量为基础)。追溯到1952年，在圣劳伦斯海洋哺乳动物的样本中检测到了三聚氰胺甲醇。三聚氰胺甲醇与大多数其他高相对分子质量有机氯有显著的相关性。在游隼的卵中也发现了一种以前没有报道的化合物，三(氯苯基)甲烷(TCP甲烷)。通过电子捕获GC或GC/MS对样品进行分析，通过质谱学特征和与合成标准的比较，完成了对TCP甲醇的鉴定。利用其质谱学特征对其进行了鉴定。三聚氰胺甲醇的广泛分布表明，它对环境有很大的投入。三聚氰胺甲醇和三聚氰胺甲烷的可能来源包括光学活性聚合物、农用化学品和用于生产合成染料的化合物。
This study presents levels of tris(4-chlorophenyl)methanol (TCP methanol) in marine mammals and bird eggs from the Arctic, Antarctic, Australia, and the East and West Coasts of North America. TCP methanol was detected in all the samples analyzed, except three milk samples (i.e., one Antarctic fur seal and two Australian sea lions). The highest levels of TCP methanol were recorded in polar bear (Ursus maritimus) livers at a geometric mean level of 5200-mu-g/kg (fat weight basis). TCP methanol was detected in samples from St. Lawrence marine mammals dating back to 1952. TCP methanol was significantly correlated with most other high molecular weight organochlorines. A previously unreported compound, tris(chlorophenyl)methane (TCP methane), was also identified in peregrine falcon eggs. Samples were analyzed by either electron capture GC or GC/MS. Identification of the TCP methanol was accomplished by its mass spectrometric characteristics and by comparison to a synthesized standard. TCP methane was identified by its mass spectral characteristics. The extensive distribution of TCP methanol suggests substantial input into the environment. The possible sources of the TCP methanol and TCP methane include optically active polymers, agrochemicals, and compounds used in the production of synthetic dyes.
