THE NATIONAL ACADEMIES

Advisers to the Nation on Science, Engineering, and Medicine


The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.


The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.


The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.


The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Preface

Extremely hazardous substances (EHSs)2 can be released intentionally through terrorist activities or accidentally as a result of chemical spills, industrial explosions, fires, or accidents involving railroad cars or trucks transporting EHSs. EHSs can also be released because of improper storage or handling. Workers and residents in communities surrounding industrial facilities where EHSs are manufactured, used, or stored and in communities along the nation’s railways and highways are potentially at risk for exposure to airborne EHSs during accidental or intentional releases. Pursuant to the Superfund Amendments and Reauthorization Act of 1986, the U.S. Environmental Protection Agency (EPA) has identified some 400 EHSs on the basis of data on acute lethality in rodents.

As part of its efforts to develop acute exposure guideline levels for EHSs, EPA and the Agency for Toxic Substances and Disease Registry (ATSDR) in 1991 requested that the National Research Council develop guidelines for establishing such levels. In response to that request, the National Research Council published Guidelines for Developing Community Emergency Exposure Levels for Hazardous Substances in 1993. Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Substances, published in 2001, provided updated procedures, methods, and other guidelines used by the National Advisory Committee (NAC) on Acute Exposure Guideline Levels for Hazardous Substances and the National Research Council Committee on Acute Exposure Guideline Levels (AEGLs) in developing the AEGL values.

Using the 1993 and 2001 National Research Council guidelines reports, the NAC—consisting of members in EPA, the Department of Defense (DOD), the Department of Energy (DOE), the Department of Transportation (DOT), other federal and state governments, the chemical industry, academe, and other organizations in the private sector—has developed AEGLs for about 200 EHSs.

In 1998, EPA and DOD requested that the National Research Council independently review the AEGLs developed by the NAC. In response to that request, the National Research Council organized within its Committee on Toxicology the Committee on Acute Exposure Guideline Levels, which prepared the present report.

At its meetings, the committee hears presentations from NAC staff and its contractors on draft AEGL documents. At some meetings, the committee also hears presentations from the NAC’s collaborators in other countries, such Germany and the Netherlands. The committee provides comments and recommendations on those documents to the NAC in its interim reports, and the NAC uses the comments to make revisions. The revised documents are presented to the committee by the NAC at later meetings until the committee concurs with the final draft documents. The revised documents are then published as appendixes in the committee’s reports.

The present report is the committee’s 17th interim report. It summarizes the committee’s conclusions and recommendations for improving the NAC’s AEGL documents for 17 chemicals: acetaldehyde, arsenic trioxide, benzene, 1,3-butadiene, butane, chloroacetaldehyde, chlorobenzene, hexane, jet propellant fuels 5 and 8, ketene, methylene chloride, oleum, propane, propionaldehyde,

sulfuric acid, sulfur trioxide, and trichloroethylene. The report also summarizes the committee’s conclusions and recommendations for improving the Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Substances, published in 2001. Committee member Robert Snyder recused himself from discussion of the draft AEGL document for benzene.

This report has been reviewed in draft form by persons chosen for their diverse perspectives and technical expertise in accordance with procedures approved by the National Research Council Report Review Committee. The purpose of the independent review is to provide candid and critical comments that will assist the institution in making its published report as sound as possible and ensuring that the report meets institutional standards of 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 thank the following for their review of this report: Harvey Clewell, The Hamner Institutes for Health Sciences; Sammuel Kacew, University of Ottawa; and Kenneth Still, Occupational Toxicology Associates. Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations, nor did they see the final draft of the report before its release. The review of the report was overseen by Robert Goyer, University of Western Ontario. Appointed by the National Research Council, he was responsible for making certain that an independent examination of the report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the author committee and the National Research Council.

The committee gratefully acknowledges the valuable assistance provided by the following: Iris Camacho and Ernest Falke, EPA; Sylvia Talmage, consultant to EPA; and Peter Bos, Joanne Nijhof, and Marcel van Raaij, the National Institute for Public Health and the Environment of the Netherlands.

The committee acknowledges James J. Reisa, director of the Board on Environmental Studies and Toxicology, for his helpful guidance and Raymond Wassel, project director, for his work on this project. Other staff members who contributed to this effort are Keegan Sawyer (associate program officer), Norman Grossblatt (senior editor), Mirsada Karalic-Loncarevic (manager, Technical Information Center), Radiah Rose (manager, Editorial Projects), and Orin Luke (senior program assistant). Finally, I thank all members of the committee for their expertise and dedicated effort throughout the development of this report.

Extremely hazardous substances (EHSs) can be released accidentally as a result of chemical spills, industrial explosions, and other accidents, or intentionally through terrorist activities. Workers and residents in communities surrounding industrial facilities where EHSs are manufactured, used, or stored and in communities along the nation's railways and highways are potentially at risk of being exposed to airborne EHSs during accidental or intentional releases.

To help understand the risk involved with EHSs, the National Advisory Committee (NAC) on Acute Exposure Guideline Levels for Hazardous Substances developed Acute Exposure Guideline Levels (AEGLs) for approximately 200 EHSs.

The present volume is the seventeenth interim report evaluating the AEGLs.
