Ozone Incidents in Indoor Swimming Pools J. Fluckiger Sumiswald, Switzerland Summary Too high a dose of ozone in the water of a swimming pool instantly gave rise to an intensive cough among a school class. All the boys and girls immediately had to leave the water and the pool, except one. This boy was used to ozone, because he swam in this pool every day. Illnesses as a result of this even were not observed. Publish Date: 1994
