NIOSH (National Institute for Occupational Safety and Health) Revised Recommendation for an Occupational Exposure Standard for Benzene

摘要

In 1974, the National Institute for Occupational Safety and Health (NIOSH) issued criteria and recommendations for a cause-and-effect relationship between benzene and observed blood abnormalities, especially aplastic anemia, was recognized. At that time, NIOSH recognizing that there were data suggesting a relationship between exposure to benzene and the occurrence of leukemia among employees at risk of such exposure, expressed its need for detailed comprehensive epidemiologic investigations of the long-term relationships of morbidity and mortality due to leukemia and other malignancies in the population at large and in those who work with benzene.
