The pharmaceutical industry is the one which produce many sorts of and small amounts of chemical substances. So that, the pollution resulting from its effluent must be different from that occurred by the other plants such as petrochemical or paper pulp factories. Then, it will not be available to estimate the pollution of the pharmaceutical effluent by the standard methods of measuring BOD or COD. The authors, in order to assess the environment of the river Hino and prevent it from the worsening by a certain pharmaceutical factory, attempted to analyze the effluents from the plants operating now in Japan. These water samples were concentrated by the low or high temperature adsorption methodand analyzed by GC-MS method. As a result of this, it was found that the pharmaceutical effluents consisted of many complicated organic compounds containing nitrogen, oxygen, sulfur and chlorine and some of them were not clarified by mass spectoscopy. It was also important that the main products were not detected and the by-products or others were contained in the effluents. This means that the preventing plan of such effluents is difficult to estimate before hand. In this paper, the analyzlng process about the micro amounts of unknown compounds and the analyzlng results of the some typical pharmaceutical effluents have been presented.
