吸烟与接触棉尘对棉纺工人呼吸系统的影响

Effect of Smoking and Cotton Dust Exposureon Respiratory System

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。

One hundred workers (68 smoking workers) fvm two textile mills were studied and 38 male workers (25 smoking workers) from a silk weaving factory without cotton exposure were selected as control.The results of this investigation revealed that the morbidity of byssinosis and chronic bronchitis were increased by the combined action of cotton dust exposure and smoking. Pulmonary function tests showed that △FEV1%>5% was higher in smoking cotton workers than that in no-smoking cotton workers. Analysis of factor suggested that the effect of cotton dust on the reduction of FEV1, in textile workers after work was obvious, while the effect of smoking wasn't. It also showed that smoking and cotton dust have no interactive effect but synergistic action.
