ozone meter OZ-ONE

The impact of ozone on human beings

The sensitivity to ozone depends on its concentration and varies

for each individual. Ozone is an oxidative irritant gas, affecting

eyes, nose, pharynx and lungs even at low concentrations. The

mucous membranes are unable to stop it seeing as ozone is

hardly soluble in water. As a result, the gas can be carried

deeper into the lungs than other irritant gases. Concentrations

of 200µg/mm

and higher can cause the following symptoms:

• irritations of the mucous membranes, eyes and the

respiratory tract

• hoarseness, coughs and headaches

• feeling of constriction behind the sternum

• reduced physical performance

The main damage is caused in the respiratory tract which can

lead to breathing difficulties and a reduced respiratory volume.

Late complications can include nosebleeds, a bronchitis (or

tracheitis) or a pulmonary oedema. But the transition from

irritations without lasting consequences to long-term changes

with pathological significance is very smooth.

Ozone threshold and target values

The information threshold for ozone concentrations amounts to

180µg/m

(1-hour value) and the alert threshold is 240µg/m

(1-hour value). From an ozone concentration of 180µg/m

the

media starts to inform the public of the recommended

behaviour. Furthermore, a target value has been specified to

protect human health: Averaged over three years, the daily

maximum 8-hour value of 120µg/m

must not be exceeded on

more than 25days per calendar year. In the long run, the

maximum average values determined over an 8-hour period are

not supposed to exceed 120µg/m

altogether. To protect the

vegetation, a target value of 18,000µg/m

applies for a 5-year

average. This is the summed up difference between the hourly

average values above 80µg/m

measured during the daylight

hours (8a.m. to 8p.m.) in the main growing season between

May and July and 80µg/m
