Environmental Health Criteria: Biomarkers in Risk Assessment: Validity and Validation, Series No. 222 (Paperback)

This publication seeks to provide a framework for selecting and validating biomarkers for risk assessment. Initial chapters consider the role of biomarkers in risk assessment and their validity. A biomarker is any substance, structure or process that can be measured in the body or its products and influence or predict the incidence of outcome or disease. Biomarkers can be classified into markers of exposure, effect and susceptibility. If biomarkers are to contribute to environmental and occupational health risk assessments, they have to be relevant and valid. Relevance refers to the appropriateness of biomarkers to provide information on questions of interest and importance to public and environmental health authorities and other decision-makers.
