4. Background of development
Ozone is a colorless toxic gas. It is irritating to eyes and mucous membranes and can cause respiratory complaints. With ozone concentrations increasing world-wide, especially in the summer time, ozone testing becomes more and more important.
An ozone content of 180 μg/m3 in the air is considered as critical value above which sensitive persons should avoid strong physical exertion. The ozone values published in the media only represent the ozone concentrations in the vicinity of the measuring stations. However, actual ozone values in other locations can deviate considerably from these published values due to meteorological and chemical influences. The reasons for such deviations are for wind, solar radiation, exhaust gases from vehicles etc. For this reason an on-site measurement of ozone concentrations is recommended.
