Triangulation in Environmental Epidemiology for EPA Human Health Assessments: Proceedings of a Workshop |The National Academies Press - ISS-G20 Laboratorium Repository

Human health risk assessments provide the basis for public health decision-making and chemical regulation in the United States. Three evidence streams generally support the development of human health risk assessments - epidemiology, toxicology, and mechanistic information. Epidemiologic studies are generally the preferred evidence stream for assessing causal relationships during hazard identification. However, the available studies may be limited in scope, subject to bias, or otherwise inadequate to inform causal inferences. In addition, there are challenges in assessing coherence, validity, and reliability during synthesis of individual epidemiological studies with different designs, which in turn affects conclusions on causation.
