title: The role of biomarkers in derivation of WHO-guidance values for air pollutants.
abstract: The Air Quality Guidelines for Europe (AQG) have provided a basis for the control of air pollution, and have contributed to the maintenance and improvement of public health in several countries. The process of updating and revision of the AQG will be completed by 1996. The applicability of biomarkers for derivation of health-based guidelines will depend on the validation of biomarkers also at low (environmental) levels of exposure, the availability of adequate population studies using biomarker information, and the development of better quantitative relationships between ambient levels, biomarker concentrations and, ideally, effects.
