Publisher description
Excerpt from Assessing Human Health Risks From Chemically Contaminated Fish and Shellfish: A Guidance Manual; September, 1989This manual provides guidance only, and does not constitute a regulatory requirement of any kind. The technical content is consistent with approved epa procedures for risk assessment, as published in the Federal Register (us. Epa 1986a-e). The guidance manual is intended to describe what epa believes to be the most scientifically defensible methods for assessing environmental health risks. These are the methods epa will use in conducting health risk assessments te quired in its statutorily mandated programs. The relationship between these procedures and risk assessment approaches used by fda is described briefly in the background section below.Background information on available health risk assessment guidance and use of this manual is provided in the remainder of this introduction. An overview of risk assessment is provided in the following section, including a discussion of the distinction between risk assessment and risk management, and a review of their possible uses. The major steps of the risk assessment process recommended herein are described in subsequent sections. Guidance is provided on mathematical models used to estimate chemical exposure and risk. Sources of information on toxic chemicals and model variables are noted. Finally, suggestions for presentation of risk assessment results are provided and uncertain ties are summarized.Risk analysis encompasses both risk assessment and risk management. Risk assessment is a scientifically based procedure to estimate the probability of adverse health effects from a specific exposure to a toxic agent. Risk assessment differs from risk management, although both are elements of regulatory decision-making (national Research Coun cil Risk assessment provides the scientific basis for public policy and action. In risk management, risks are interpreted in light of legis lative, socioeconomic, technical, and political factors, and appropriate controls are determined. Risk management often involves evaluating risks relative to potential benefits associated with an activity and defining an acceptable risk level the maximum risk considered tolerable). For example, a risk manager might weigh the risks as sociated with chemical contamination of fish and shellfish against the health benefits decreased risk of heart disease) associated with consumption of fish and shellfish in place of red meat.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
