Risk Assessment

Abstract

Risk assessment is the process of determining the nature and extent of risks to human health and the environment. In a widely cited report, Risk Assessment in the Federal Government: Managing the Process (often referred to as the “Red Book”), risk assessments for human health are broadly defined as “the characterization of the potential adverse health effects of human exposures to environmental hazards”(NRC, 1983). The Red Book also details the main elements of the risk assessment process, including a description of potential adverse health effects (based on epidemiological, clinical, toxicological, and environmental research); extrapolation from available data to predict the type and estimate the extent of health effects in humans under certain exposure conditions; evaluation of the number and characteristics of persons exposed at various intensities and durations; and characterization of the overall magnitude of the public health problem and any uncertainties inherent in the process of inferring risk (NRC, 1983).
