两个棉纺厂的100名男工(其中吸烟者68名)作为调查对象,另选无棉尘接触的丝织厂男工38名(其中吸烟者25名)作为对照。本调查结果表明,接触棉尘和吸烟的联合作用促使棉尘症和慢性支气管炎患病率升高。在肺功能测定方面,△FEV1%≥5%者吸烟棉纺工高于不吸烟棉纺工。析因分析提示棉尘对班后FEV1下降有极显著影响,而吸烟却未见明显影响。这亦表明吸烟和棉尘没有交互影响,但有协同作用。 A total of 100 male workers (68 of them smokers) from two cotton mills were selected as survey respondents. Thirty-eight (including 25 smokers) workers in the silk mill with no cotton dust were selected as controls. The findings of this survey indicate that the combined effects of exposure to cotton dust and smoking have led to an increased prevalence of cotton dust disease and chronic bronchitis. In lung function tests, △ FEV1% ≥5% of those who smoke cotton spinning workers than non-smoking cotton spinning workers. Factor analysis indicated that cotton dust had a very significant effect on the fall of FEV1 after class, while smoking had no obvious effect. It also shows that there is no interaction between smoking and cotton dust, but there is synergy.
