Ethyl acetate extracts of river waters and sediments, night-soil and sewage treatment plant effluents and sludges from the Tokyo area were analysed for squalane using combined gas chromatography-mass spectrometry after separation by silica gel column chromatography. Squalane was identified in all the samples studied and the concentration in river waters and sediments ranged from 0.46 to 1.7 micrograms/l and from 0.86 to 15 micrograms per g dry sediment, respectively. Squalane is presumably derived from artificial materials rather than from natural sources, with the exception of fossil fuel products.
采用硅胶柱色谱分离后，运用气相色谱 - 质谱联用技术对东京地区河水、沉积物、夜粪以及污水处理厂废水和污泥的乙酸乙酯提取物进行角鲨烷分析。在所研究的所有样品中均鉴定出了角鲨烷，其在河水中的浓度范围为0.46至1.7微克/升，在干沉积物中的浓度范围为0.86至15微克/克。除化石燃料产品外，角鲨烷可能源自人工材料而非天然来源。
