Résumé

The concentration of airborne particulate matter (PM(2.5) and PM(10)) was assessed over 12 months (1999-2000) both outdoor and indoor (workplaces and homes without major PM sources) through a manual gravimetric method. Mean concentration values outdoors were moderately lower than indoor concentration in summer, but higher in winter. The correlations between outdoor and indoor values are statistically significant, especially for PM(2.5) in winter. The position of indoor sites with respect to street level was immaterial as far as mean values is concerned, whilst maximum values presented some differerences accordingly. Day-to-day variability was higher outside than inside, especially in winter. The PM(2.5)/PM(10) ratio was higher indoors, probably owing to the higher sedimentation speed of the coarse fraction.
