关于氯甲烷对人体的危害性问题,许多学者已从临床、毒理、毒性等方面近行了大量研究。但氯甲烷作业工人免疫状态的变化,国内尚未见报导。为了给制定诊断标准和处理原则提供科学依据,笔者1982、1984两年先后2次对氯甲烷作业工人近行了免疫状态及微核的观察。观察对象:以自贡市鸿化厂生产氯甲烷的112名工人为观察组,其中男77人,女35人,工龄3～20年。同时以不接触有毒物 On the issue of methyl chloride hazards to humans, many scholars have from the clinical, toxicology, toxicity and other aspects of a lot of recent research. However, changes in the immune status of workers exposed to methyl chloride have not been reported in China. In order to provide a scientific basis for the development of diagnostic criteria and principles of treatment, the author of 1982,1984 two times successively two times on the methane workers in the immune status and micronucleus observed. Observe: 112 workers who produce methyl chloride in Honghua Plant of Zigong City are observation group, 77 males and 35 females, with a working life of 3 to 20 years. At the same time to avoid contact with toxic substances
