蓝棉是一种棉制品，带有铜酞菁三磺酸盐作为共价连接的配体，并且是对具有三个或更多个稠环的化合物具有特异性的吸附剂。由于这种特殊的性质，蓝棉已被用于从原材料中提取致突变的多环化合物。作者在前期工作中简要介绍了用蓝棉监测河水致突变性的结果。最近，他们改进了吸附剂的质量;用人造丝代替棉作为配体的载体，并制备了更强的吸附剂，蓝色人造丝，其含有的配体量是蓝色棉的2-3倍。在本文中，作者报告了使用蓝色人造丝方法检测淀川中的致突变化合物，淀川流经京都和大坂，是该地区1000万人的主要饮用水来源。
Blue cotton is a cotton preparation, bearing copper phthalocyanine trisulfonate as a covalently linked ligand, and is an adsorbent specific for compounds with three or greater number of fused rings. Due to this special property, blue cotton has been used for extracting mutagenic polycyclic compounds from crude materials. In early work, the authors gave a brief account of the results of monitoring river-water mutagenicity with blue cotton. Recently they have improved the quality of the adsorbent; rayon in place of cotton was employed as the support for the ligand, and a more powerful adsorbent, blue rayon, which contains 2-3 times greater amount of the ligand than blue cotton, was prepared. In this paper the authors report the use of the blue-rayon method to detect mutagenic compounds in the Yodo river, which flows through the cities of Kyoto and Osaka and is a major source of drinking water for the 10 million people in the area.
