The authors analyse the data connected with chronic pulmonary diseases (mainly bronchitis) of two groups of workers, both belonging to the same metallurgical factory. The data is taken in two different periods, before and after the introduction of measures for primary prevention in the factory. The results confirm that the overall cases of pulmonary diseases are greatly reduced by a correct improvement in the working environment. Moreover, they confirm that a dangerous working environment affects the breathing system more prominently then other factors such as smoking, etc.
作者分析了同一冶金厂两组工人与慢性肺部疾病（主要是支气管炎）相关的数据。这些数据取自工厂采取一级预防措施之前和之后的两个不同时期。结果证实，通过正确改善工作环境，肺部疾病的总体病例数大幅减少。此外，他们证实，危险的工作环境对呼吸系统的影响比吸烟等其他因素更为显著。
