Niveau de pollution par le SO2 et prévalence de la bronchite

Abstract

The prevalence of chronic bronchitis (according to the BMRC questionnaire on respiratory symptoms) for 1182 male smokers, as well as their peak flow rate, are related to age (18-65 years), cagarette consumption (1-55 cig./day) and exposure to atmospheric SO2 pollution (20-65 microgram/m3).
