TAILIEUCHUNG - Traffic-related air pollution associated with prevalence of asthma and COPD/chronic bronchitis. A cross-sectional study in Southern Sweden

The population exposure without PM10 fraction attributable to road traffic is shown in Figure 6. Compared to total PM10, the frequency distribution changes considerably. Most people would live in areas with PM10 values less than 20 µg/m3. In France and Switzerland, less than 3% of the population would live in areas with PM10 greater than 20 µg/m3. In Austria, this portion is higher due to an increased non-traffic caused regional PM10 background. However, in all three countries, the reduction of the percent values in higher PM10 concentration classes is substantial and indicates that road traffic contributes considerably to these PM10 concentration classes.

Abstract Background There is growing evidence that air pollution from traffic has adverse long-term effects on chronic respiratory disease in children but there are few studies and more inconclusive results in adults. We examined associations between residential traffic and asthma and COPD in adults in southern Sweden. A postal questionnaire in 2000 n 9319 18-77 years provided disease status and self-reported exposure to traffic. A Geographical Information System GIS was used to link geocoded residential addresses to a Swedish road database and an emission database for NOx. Results Living .
