Abstract
The number of people, living in the monitorized areas of the city of Turin with a homogeneous pollution, who entered hospital because of an afebrile new acute episode of chronic bronchitis was studied. In the period dating from February 1st, 1975, to April 30th, 1976, this number appears to be related to the pattern of pollution from sulfur dioxide, total dust, submicronic aerosols, vanadium, zinc, cadmium, and to the decrease of atmospheric temperature; it is not related to air content of carbon monoxide and nitrogen oxides. The latency between peaks of pollution and recoveries was of 2.9 days as regards submicronic aerosols, and of 3.9 days as regards remainder pollutants. The monthly inhalable amount of sulfur dioxide appears to be the uppermost joint cause of new acute episodes of chronic bronchitis. Domestic heating seems to be the main origin of pollutants related to recoveries. Factors influencing the highest number of recoveries happen mostly during the months of January and February; a transfer of patients suffering from chronic bronchitis to a climatic site, restricted this period, seems to be preferable than treatment in hospitals located in polluted areas and hence not completely fit for an aetiological treatment of the in study pathology.
