Outline of Final Research Achievements

The purpose of this study was to verify more effective methods for preventing health hazards by comparing appropriate measurement and evaluation methods by simultaneously conducting AB measurement, CD measurement, and individual exposure concentration measurement based on these working environment standards, which are usually conducted. As a method, in addition to differences in these measurement methods, differences in sampling time, That were also examined, and as a result, a method more effective in preventing health problems was verified.
CD measurement and individual exposure measurement in combination with AB measurement could detect large exposures that could not be detected by AB measurement alone. In addition, it was found that correct evaluation is possible by setting the group of equally exposed workers correctly in the selection of measurement targets when conducting CD measurement and individual exposure measurement. Based on the results of the above studies.

Academic Significance and Societal Importance of the Research Achievements

インジウム化合物取り扱い事業所にて、特に測定濃度が高いことが予測されるため現行のB測定に加えて短時間ばく露測定の有用性について検討し、基礎的なデ－タを得た。また、長時間サンプリング測定のおよび短時間ばく露測定の検討に加え、実際のばく露状況が良く反映され評価方法ついても検討した。その結果、一定の測定方法を用いるのみでなく、実際の現場の問題点に合わせた方法と評価を選択することの重要性が示された。最も有益で合理的な健康障害防止に有効な測定方法を用いることの必要性が明確となり、今後のインジウム化合物ばく露による健康障害防止において、大変重要な知見を得た。
