On the second of January, 1970, it was happened that a stinking water was distributed in Tokyo City. This water was supplied from the Asaka Water Supply Plant. Then, the origin of the stinking water has been in vestigated. The work has been continued during about a year. With the results of this, it was found that the river water at that time contained many chemical substances, which might be considered to exhaust from the factories lied upstream. And it was defined to generate the stinking compounds by the chlorination of these pollutants. The compounds remained in the stinking water were containing chlorinated compounds, bromonated compounds and hydrocarbons, such as dichloroethylene, methylene chloride, chloroform, trichloroethylene, dichloroethane, methyl bromide, bromodichloromethane, benzene, toluene and cyclohexene etc. In addition to this, charcoals treated the stinking water and the normal river samples were analyzed. Finally, cyclohexylamine was presumed to be the original substance. However, the most important fact was as follows that the GC-MS technique was for the first time applied to the environmental investigation. This is nothing but a reason for reporting the paper. After that GC-MS has been widely using and its availability was proved as a micro-identification technique necessary for environmental samples. So that, the authors appreciated the effort taken to introduce it to the environmental science.
