English Abstract Since June 20, 1991 a new smog regulation exists in the
Netherlands which is called: Smog Procedures 1991. This procedure
constitutionalises the implementations of measures, actions,
smog-alertsystems and recommendations during periods of high levels of air
pollution (summer and water smog). In this report an overview is given of
the smog situation in the Netherlands in the summer of 1992. A number of
periods of elevated air pollution (summer smog) have been registered during
the months of April up to September 1992. Summer smog consists of a mixture
of a large number of substances. It is identified on the basis of the
atmospheric ozone concentration, since ozone has the greatest impact on
public health. The ozone concentrations, which are measured by the National
Air Quality Monitoring Network (LML), are compared with the Dutch draft
ozone standard and the EC-quideline ozone.
