The water or sea contamination of diisopropyl naphthalene and phenyl xylylethane in hydrocarbons, which have appeared as alternatives for polychlorobiphenyls, was examined in some areas of Japan. A mass fragmentgraphic technique was applied for rapid determination of trace amounts. In sea mud, 0.019 to 0.16 ppm of diisopropyl naphthalene was found, and a few ppm in fish, but no phenyl xylylethane was detected in any samples. The necessity for continuous survey for contamination by new chemicals and the availability of the mass fragmentgraphic method for difficult microdetermination by gas chromatography, using an electron capture detector, are emphasized.
在日本的一些地区，对作为多氯联苯替代品出现的碳氢化合物中二异丙基萘和苯基二甲苯乙烷的水或海水污染情况进行了检测。采用质量碎片图谱技术快速测定痕量物质。在海泥中发现了0.019至0.16 ppm的二异丙基萘，在鱼类中发现了几ppm，但在任何样品中均未检测到苯基二甲苯乙烷。强调了对新化学品污染进行持续监测的必要性，以及质量碎片图谱法在使用电子捕获检测器进行气相色谱法难以进行的微量测定方面的实用性。
