From 1st August 1990 onwards health complaints in connection with chemical product exposure were assessed by an official monitoring system. The reports of the primary care physicians are documented in a standardized form, assessed, evaluated and analysed. Results are reparted and recommendations for risk management are directed to the published. Beside the systematic documentation of human toxicological data in form of standard files and case-reports, the monitoring system has an important toxicovigilance function: Serious health effects from acute or chromic chemical product exposure are analysed immediately, all other health complaints from exposures annually and directed for risk-management to the producers, distributors, industrial associations and the government.
