The Working Group agreed to give examples of concentrations, which may serve as

alert or information thresholds (Table 2.3). These should be directly health related and

increase the awareness of the general public. It was concluded that it will be confusing

to define an information threshold that can apply generally all over Europe from south

to north and from large urban areas to smaller residential areas, because the air quality

is different. The Working Group considered defining alert thresholds as well as

information thresholds using the principles of the O3 directive. Table 2.3 gives

examples of thresholds and the corresponding observed effects of exceedings. Several

Member States have set different alert values. Denmark has set an alert values of 350

Tg/m; for 1 hour average, but the alert is only issued, if the episode is expected to

last more than 12 hours. Austria has set a pre-alert value of 350 Tg/m; and also alert

levels at 600 and 800 Tg/m; as 3-hour means.
