Abstract
In the past two decades several incidents of environmental pollution have become known in which people might have been exposed to the contaminating substances. In the Netherlands the National Poison Control Centre, a department of the National Institute of Public Health and Environmental Protection, plays a distinct role in dealing with the health problems arising from these incidents.
The health risk assessment of an environmental incident may be facilitated by utilizing a logical predetermined sequence of decision steps in order to avoid inappropriate responses which could induce many untoward effects within the population of the contaminated area.
As an example of this general approach, the handling of a recent incident with mercuric chloride is described.
