[Short-term effects of ozone on respiratory health of children in Armentières, North of France].

Background: We studied short-term respiratory effects of ozone in a panel of 91 ten-year old children from a school in Armentières, North of France.

Methods: Each child reported twice daily peak expiratory flow rate measurements (mini-Wright) and daily occurrence of respiratory symptoms, from April 1, 1996 to June 30, 1996. Outdoor ozone measurements were obtained from a continuous fixed monitor, located at 850 meters from the school.
