CHAPTER 1
INTRODUCTION
This guide was developed in response to a technical
assistance request (TAR 29) from U.S. EPA Region VIII to compile
a list of existing health-related values (inhalation equivalent
only) for thirty-four individual pollutants. The pollutants are
listed below:
VOCs: Metals;
Benzene Arsenic
Carbon Tetrachloride Beryllium
Chlorobenzene (MCB) Cadmium
Chloroform Chromium
1,4-Dichlorobenzene Lead
1,2-Dichloroethane
1,1-Dichloroethene Pesticides;
C-l,2-Dichloroethene
C-l,3-Dichloropropene Aldrin
T-l,3-Dichloropropene Chlordane
Ethylbenzene DDT
Formaldehyde Dieldrin
Methylene Chloride Heptachlor
1,1,2,2-Tetrachloroethane Toxaphene
Tetrachloroethene (PCE)
Toluene
1,1,1-Trichloroethane (Methyl Heavy Organic Compounds;
chloroform)
1,1,2-Trichloroethane Benzo (a) pyrene
Trichloroethylene PCBs
Vinyl Chloride
Total Xylenes
Health-related values were identified from sources such as
the American Conference of Governmental Industrial Hygienists
(ACGIH), the National Institute for Occupational Safety and
Health (NIOSH), and the Occupational Safety and Health
Administration (OSHA). Ambient air standards were also
identified from States around the country. A summary of the data
gathering effort involved the following for each pollutant
identified:
• Searching both scientific literature and State
regulations for all health related concentrations
• Preparing a listing of each concentration or limit
• Providing definitions of each of the common values
listed
1-1
-------
• Preparing a listing of compound synonyms and health
effect descriptions.
Chapter 2 contains the inhalation exposure limits that were
identified for each of the thirty-four pollutants ranked by
exposure limit. Note that for the metal categories, data was
collected for only the metal listed and not for the many
compounds that might contain the metal. Appendix A contains the
references used to develop the tables in Chapter 2. Appendix B
contains an alphabetical listing of the thirty-four pollutants
and their synonyms. Appendix C contains a listing of the common
acronyms and abbreviations of the thirty-four pollutants;
definitions of the common values used; and each of the references
which were cited.

16. ABSTRACT
This report compiles a list of existing health-related values (inhalation equivalent only) for 34
individual pollutants [volatile organic compounds (VOCs), metals, pesticides, and heavy organic
compounds]. Health-related values were identified from sources such as the American Conference of
Governmental Industrial Hygienists (ACGIH), the National Institute for Occupational Safety and Health
(NIOSH), and the Occupational Safety and Health Administration (OSHA). Ambient air standards were
also identified from States around the country. The data gathering effort involved the following for each
pollutant identified:
0 Searching both scientific literature and State regulations for all health related
concentrations
0 Preparing a listing of each concentration or limit
0 Providing definitions of each of the common values listed
0 Preparing a listing of compound synonyms and health effect descriptions.
This report also contains the inhalation exposure limits that were identified for each of the 34
•pollutants ranked by exposure limit.
