The United States Navy has been concerned for some time with protecting its military and civilian personnel from reproductive and developmental hazards in the workplace. As part of its efforts to reduce or eliminate exposure of Naval personnel and their families to reproductive and developmental toxicants, the Navy requested that the National Research Council (NRC) recommend an approach that can be used to evaluate chemicals and physical agents for their potential to cause reproductive and developmental toxicity. The NRC assigned this project to the Committee on Toxicology, which convened the Subcommittee on Reproductive and Developmental Toxicology, to prepare this report. In this report, the subcommittee recommends an approach for evaluating agents for potential reproductive and developmental toxicity and demonstrates how that approach can be used by the Navy. This report has been reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise, in accordance with procedures approved by the NRC's Report Review Committee. The purpose of this independent review is to provide candid and critical comments that will assist the institution in making its published report as sound as possible and to ensure that the report meets institutional standards for objectivity, evidence, and responsiveness to the study charge. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process. We wish to thank the following individuals for their review of this report: James Chen (National Center for Toxicological Research), George Daston (Procter and Gamble Company), Jerry Heindel (National Institute of Environmental Health Sciences), Grace Lemasters (University of Cincinnati), and John Young (National Center for Toxicological Research).

People are exposed to a variety of chemicals throughout their daily lives. To protect public health, regulators use risk assessments to examine the effects of chemical exposures. This book provides guidance for assessing the risk of phthalates, chemicals found in many consumer products that have been shown to affect the development of the male reproductive system of laboratory animals. Because people are exposed to multiple phthalates and other chemicals that affect male reproductive development, a cumulative risk assessment should be conducted that evaluates the combined effects of exposure to all these chemicals. The book suggests an approach for cumulative risk assessment that can serve as a model for evaluating the health risks of other types of chemicals.

Evaluates federal regulatory actions on environmental chemicals known to cause adverse reproductive and developmental outcomes. Identifies 30 environmental chemicals found to be of high concern because of the widespread acknowledgment of their reproductive and developmental consequences as toxicants. Determines the extent to which these chemicals are regulated by the federal government. Assesses the degree to which these regulatory actions are based on reproductive and developmental toxicity. Evaluates whether the regulatory protection currently provided to the public against reproductive and developmental disease is sufficient.

The public depends on competent risk assessment from the federal government and the scientific community to grapple with the threat of pollution. When risk reports turn out to be overblownâ€"or when risks are overlookedâ€"public skepticism abounds. This comprehensive and readable book explores how the U.S. Environmental Protection Agency (EPA) can improve its risk assessment practices, with a focus on implementation of the 1990 Clean Air Act Amendments. With a wealth of detailed information, pertinent examples, and revealing analysis, the volume explores the "default option" and other basic concepts. It offers two views of EPA operations: The first examines how EPA currently assesses exposure to hazardous air pollutants, evaluates the toxicity of a substance, and characterizes the risk to the public. The second, more holistic, view explores how EPA can improve in several critical areas of risk assessment by focusing on cross-cutting themes and incorporating more scientific judgment. This comprehensive volume will be important to the EPA and other agencies, risk managers, environmental advocates, scientists, faculty, students, and concerned individuals.

and for those interested in toxic effects of chemicals on humans, Human Variability in Response to Chemical Exposures: Measures, Modeling, and Risk Assessment recognizes and addresses the increasing awareness that individual biological differences be reflected when assessing human health risks associated with exposure to chemicals. Eight original manuscripts, commissioned by the ILSI Risk Science Institute, address the evidence for variability in human response to chemicals associated with reproductive and developmental effects, effects on the nervous system and lungs, and cancer. Their reports convey both the current state of scientific understanding of response variability and the genetic basis for such observations. This book recognizes that understanding of variability in response is critical in accounting for interindividual variability in susceptibility and, hence, risk, if the regulatory community and others are expected to characterize human health risks associated with exposure to chemicals. Models for incorporating measures of response variability in the risk assessment process are critically reviewed and illustrated with published data. This authoritative work indicates that, in the case of certain chemicals and in the context of certain specific toxic effects, we have considerable ability to predictively and quantitatively characterize human variability, but, in the majority of cases, our ability to do so is limited. If we improve both quantity and quality of information available on response variability and increase our understanding of target tissue dosimetry, we should be better able to account for variability in human susceptibility to the toxic effects of chemicals.

Toxicity testing in laboratory animals provides much of the information used by the Environmental Protection Agency (EPA) to assess the hazards and risks associated with exposure to environmental agents that might harm public health or the environment. The data are used to establish maximum acceptable concentrations of environmental agents in drinking water, set permissible limits of exposure of workers, define labeling requirements, establish tolerances for pesticides residues on food, and set other kinds of limits on the basis of risk assessment. Because the number of regulations that require toxicity testing is growing, EPA called for a comprehensive review of established and emerging toxicity-testing methods and strategies. This interim report reviews current toxicity-testing methods and strategies and near-term improvements in toxicity-testing approaches proposed by EPA and others. It identifies several recurring themes and questions in the various reports reviewed. The final report will present a long-range vision and strategic plan to advance the practices of toxicity testing and human health assessment of environmental contaminants.

Intended as a tool for use by public health officials, research and regulatory scientists and risk managers, this publication seeks to provide a scientific framework for the use and interpretation of reproductive toxicity data from human and animal studies. It also discusses emerging methodology and testing strategy in reproductive toxicity. The text focuses on approaches to assessing reproductive toxicity in males and females, including sexual dysfunction and infertility, and many aspects of developmental toxicity (following both prenatal and postnatal exposure), from conception to sexual maturation. It is an overview of the major scientific principles underlying hazard identification, testing methods and risk assessment strategies in human reproductive toxicity. It also discusses the evaluation of reproductive toxicity data in the context of the extensive risk assessment methodology that has emerged over the past 10-15 years.
