title: [Results of spirometric examinations in workers engaged in production of iron-manganese alloys].
abstract: Spirometric examinations were performed in 205 workers engaged in production of iron-manganese alloys. It was found that mean values of FEV1, FEV1%, PEFR, MEF25%-75% VC and MMF were significantly lower in persons above 40 years of age, smokers and in those suffering from chronic bronchitis in comparison with people below the age of 40, non-smokers and persons free from chronic bronchitis. No relationship between the length of employment and the ventilation capacity was found.
