title: [The effect of inhalable dust particles (PN10) on lung function and respiratory symptoms of school children in Lower Austria].
abstract: The effect of PM10 (particulate matter less than 10 microns in diameter) on respiratory symptoms and lung function was evaluated in 881 children (aged 8 to 11 years) in 8 communities in Lower Austria. In each community, air pollution data (PM10, SO2, NO2, O3) were collected. The examination of each child included a questionnaire (spring 1996), and two lung function tests (autumn 1995, spring 1996). Statistically significant relationships were observed between PM10 levels (annual mean, 15.8-26.9 micrograms/m3) and parameters of lung function (adjusted for sex, height, atopy, passive smoking, altitude, temperature). A 10 micrograms/m3 increase in the last two weeks' mean PM10 in spring 1996 was associated with a 0.05% decrease in FVC, a 0.05% decrease in FEV1, a 0.15% decrease in MEF50, and a 0.13% decrease in MEF75-25. Furthermore, a 10 micrograms/m3 increase in last year's mean PM10 was associated with a 0.07% decrease in FVC. No association between the prevalence of respiratory symptoms and the last year's mean PM10-exposure was found. Our study demonstrates a small effect of low-level particulate air pollution on lung function of healthy school children.
