简介 二硫化碳是人造纤维、橡胶、杀虫剂、玻璃纸等化工产品的有机溶剂。近年来,随着轻化工业的迅速发展,二硫化碳使用量越来越大。但这种溶剂的气体对工人身体健康危害很大。因此,如何降低工厂内二硫化碳环境浓度,防治其慢性中毒受到党和政府的关切。我校卫生学教研室同志于1974年深入某化纤厂,对接触二硫化碳工人的呼气浓度及车间环境浓度进行调查研究,并将测定结果统计分析,求出两者的比率关系及其回归相关关系。结果表明,测定呼气浓度,既能反映出环境浓度,又能反映出人体体内的存留率,为今后客观评价环境浓度提供了一个指标。 本文介绍呼气浓度的测定方法及统计分析结果。
Introduction Carbon disulfide is an organic solvent for chemical products such as rayon, rubber, insecticide and cellophane. In recent years, with the rapid development of light industry, the amount of carbon disulfide used is getting larger and larger. However, the gas of this solvent is very harmful to the health of workers. Therefore, how to reduce the concentration of carbon disulfide in factories and control their chronic poisoning has come under the concern of the party and the government. In 1974, our department of hygiene department went deep into a chemical fiber factory to investigate the exhaled concentration and workshop environment concentration of workers exposed to carbon disulfide. Statistical analysis of the measurement results obtained the relationship between the two and the regression relationship. The results show that the determination of expiratory concentration, both to reflect the concentration of the environment, but also reflect the retention rate in the human body for the future objective assessment of environmental concentration provides an indicator. This article describes the determination of breath concentration and statistical analysis results.
