Frequence of occurrence and dynamics of chronic bronchitis symptoms as well as barrier syndrome in the examined men in a plant was connected primarily with tobacco smoking and less with the age. Mean values FEV1 depended on the age of examined workers and the rate of spirometric values decrease increased with the age and was connected with smoking habit. It has been ascertained that there is a direct relationship between air contamination with dusts and fluorides and frequency of occurrence of chronic bronchitis symptoms, maintenance of the symptoms for 5 years and decrease of FEV1 value at that period especially in a group of smokers.
某工厂受检男性慢性支气管炎症状以及阻塞综合征的发生频率和动态变化，主要与吸烟有关，与年龄关系较小。第一秒用力呼气容积（FEV1）的平均值取决于受检工人的年龄，肺功能测定值的下降速率随年龄增加，且与吸烟习惯有关。已确定，粉尘和氟化物空气污染与慢性支气管炎症状的发生频率、症状持续5年以及该时期FEV1值下降之间存在直接关系，尤其是在吸烟者群体中。
