                  RESEARCH REPORTING  SERIES


Research reports of the Office of Research and Development, U.S Environmental
Protection Agency, have been grouped into nine series  These nine broad cate-
gories were established to facilitate further development and application of en-
vironmental technology  Elimination of traditional grouping was  consciously
planned to foster technology transfer and a maximum interface in related fields.
The nine series are:

    1. Environmental Health Effects Research

    2. Environmental Protection Technology

    3. Ecological Research

    4. Environmental Monitoring

    5. Socioeconomic Environmental Studies

    6. Scientific and Technical Assessment Reports (STAR)

    7. Interagency Energy-Environment Research and Development

    8. "Special" Reports

    9. Miscellaneous Reports

This report has been assigned to the INTERAGENCY ENERGY-ENVIRONMENT
RESEARCH AND  DEVELOPMENT series. Reports m this series result from the
effort funded  under the  17-agency  Federal  Energy/Environment Research and
Development Program. These studies relate to EPA's mission to protect the public
health and welfare from adverse effects of pollutants associated with energy sys-
tems. The goal of the Program is to assure the rapid development  of domestic
energy supplies in an environmentally-compatible manner by providing the nec-
essary environmental data and control technology. Investigations include analy-
ses of the transport of energy-related pollutants and their health and ecological
effects;  assessments  of,  and development of,  control technologies for energy
systems; and integrated assessments of a wide'range of  energy-related environ-
mental issues.

                                  FOREWORD

     To provide for comprehensive environmental assessments of industrial
processes, the Environmental Protection Agency's Industrial Environmental
Research Laboratory at Research Triangle Park, N.  C.,is developing a method-
ology to facilitate the quantitative evaluation and comparison of industrial
discharges, emissions and effluents with respect to their potential environ-
mental impacts.  This methodology prescribes a systematic approach to the
interpretation of data obtained in environmental assessment projects.  In
order to fully characterize waste streams for such an assessment, pollutant
levels must be related to environmental effects.  Multimedia Environmental
Goals (MEGs) provide the mechanism by which this relationship may be achieved.
     This report supplements both the description of the MEGs approach given
in Volume I (EPA-600/7-77-136a, November 1977) and the background information
summaries and MEG values for some 640 chemical substances presented in Volume II
(EPA-600/7-77-136b, November 1977) and Volumes III and IV (EPA-600/7-79-176a
and b, August 1979).
     As a result of comments and recommendations from users and a critical
review panel*, the MEGs methodology is steadily undergoing modification.  One
such refinement recently adopted involves simplification of the nomenclature.
The terms Discharge MEG (DMEG) and Ambient MEG (AMEG) will replace the terms
Minimum Acute Toxicity Effluent (MATE) and Estimated Permissible Concentra-
tion  (EPC), respectively.  However, the new terms do not appear in this
report in order that the material reported herein may be more easily related
to the material in the previous MEG reports.
     Other possible future modifications include:  the incorporation of addi-
tional factors into some of the models to better account for persistence and
bioaccumulation of the chemicals in the environment; the use of risk factors
for chemical carcinogens; improved definition of uncertainties and corre-
sponding conservative assumptions in the various factors used in the MEG
models; and a  footnoting system to indicate the specific basis for each MEG
value calculated.
     Future updates of the MEGs including any revisions in the methodology
will be facilitated by the use of MEGDAT, the computerized MEGs data base, due
to become fully operational in 1980.

     Realizing the valuable role which we feel the MEGs can play in the environ-
mental assessment of industrial processes and also realizing the pioneering
nature of the methodology, we continue to welcome constructive comments from
MEGs users.

                                   Abstract

     A methodology to establish Multimedia Environmental  Goals (MEGs) for
chemical pollutants was introduced in November 1977 in a two-volume EPA report
entitled Multimedia Environmental  Goals for Environmental Assessment.  Volume I
(Supplement A) supplements the earlier MEGs report.  A summary of the original
methodology is presented and minor improvements are introduced.   These include
the assignment of unique identification numbers to each MEG compound and a
modification to the original model used to derive MEG values for land or solid
                                                                 A
waste.  Included in appendices in this volume are revised category descriptions,
an updated master list of organic compounds, a candidate list of compounds to
be considered for future MEGs, tabulated discharge MEG values, and hazard
potential values.  Graphical summaries of MEGs for 586 organic chemicals are
also included.  This volume is to be used in coordination with MEG Volumes III
and IV which contain background information summaries and MEG charts for
organic compounds in the new MEGs master list.

                                 INTRODUCTION

     To provide for comprehensive environmental  assessments, EPA's Industrial
Environmental Research Laboratory at Research Triangle Park is developing a
procedure to facilitate quantitative evaluation  and comparison of streams and
processes with respect to their potential  environmental impacts.   The method-
ology prescribes a systematic approach for interpreting data obtained in
environmental assessment projects.   The need for Multimedia Environmental
Goals (MEGs) arises in this context.  In order to fully characterize waste
streams for environmental assessment, pollutant  levels must be related to
their environmental effects.   The development of Multimedia Environmental
Goals is a first attempt at a procedural approach to evaluate and rank a large
number of pollutants for the purpose of environmental assessment.
1.1  DEFINITION
     Multimedia Environmental Goals describe levels of contaminants or degradants
(in ambient air, water, or land, or in discharges conveyed to ambient media)
that (1) are predicted not to produce negative effects in the surrounding
populations or ecosystems, or (2)  represent control limits achievable through
technology.
     MEGs are not to be treated as regulations.   They are designed for use in
ranking chemicals on the basis of predicted environmental acceptability.  The
MEG values and MEG models are frequently based on very limited data or on data
of undetermined reliability.   These limitations  should be kept in mind by
those using the numerical values from the MEG charts and tabulations.  Similar
caution is advised for those applying the models to generate MEGs for new
compounds.
1.2  BACKGROUND
     A methodology to establish MEGs for chemical pollutants was introduced in
November 1977 in a two-volume EPA report entitled Multimedia Environmental
Goals for Environmental Assessment.   Volume I of the 1977 report described a
system for generating quantitative goals for chemical substances from infor-
mation currently available in the literature.  A master list of approximately
600 chemical pollutants associated with fossil fuels processes or of specific
environmental interest was also provided in Volume I, and Minimum Acute Toxic-

-------
ity Effluents (MATE) values for air, water, and solid waste were tabulated for
many of the chemicals on the master list.   Volume II of the report contained
background information summaries and MEG charts for 216 chemical substances
selected from the master list.   Goals listed on the charts were calculated in
accordance with the methodology presented in Volume I.  In August 1979, MEG
                  2
Volumes III and IV  were issued to supplement the 1977 MEGs reports.   Back-
ground Information Summaries and MEG charts comprise Volumes III and IV.   The
methodology developed in Volume I is applied (with minor revisions) to 586
organic chemicals.  MEG values in Volumes III and IV supplant the data for
organics in earlier volumes.
1.3  DESCRIPTION OF VOLUME I (Supplement A)
     This report, Volume I (Supplement A), presents a brief description of the
MEGs methodology, including methodology and format modifications implemented
since Volume I, and provides updated appendices for organics.  Included are
revised MEG category descriptions and an updated master list of organics.   A
candidate list is also given naming compounds to be considered for MEGs in the
future.  Updated MATE values and Hazard Potential Values for the organics
addressed in Volumes III and IV are tabulated.  Graphical summaries of the
MEGs for organic compounds are also presented.  Alphabetical and molecular
formula indices are provided to reduce nomenclature problems and to assist
users unfamiliar with the MEGs categories.  A final appendix contains a com-
plete MEGs bibliography including all references from Volumes III and IV.
(References in Volumes III and IV are provided at the end of each subcategory,
but a collective list was not included.)
     Evolution of the MEGs is expected to continue as scientists develop
better understandings of mechanisms by which chemicals act on man and the
environment.  The information in this report is provided to support and en-
hance the use of the multimedia environmental goals, especially in conjunction
with the source analysis models (SAMs) being developed for EPA by Acurex Cor-
poration.   It is hoped that those  involved in environmental assessment sam-
pling and analysis will provide comments and critiques on this material and
format and thereby contribute to its incremental improvement.

                                   SECTION 2
                 SUMMARY OF THE METHODOLOGY FOR ESTABLISHING
                 MULTIMEDIA ENVIRONMENTAL GOALS FOR CHEMICALS

     The MEGs methodology introduced in Volume I of the November 1977 MEGs
report established models to calculate quantitative environmental goals for
chemicals in ambient air, water, and soil, or in gaseous, aqueous, and solid
waste discharges.   The values generated by the prescribed system of models
provide alternative goals for use in environmental assessment.   The primary
objectives of the original methodology and the system prescribed for calcula-
ting goals are summarized in this section.  The reader should refer to refer-
ence 1 for more complete details of the MEGs methodology.
2.1  TYPES OF GOALS SPECIFIED AND PRACTICAL CONSIDERATIONS
     The primary objective of the current chemical MEGs methodology is a
systematic approach that can be used to estimate for a large number of com-
pounds 1) maximum concentrations acceptable (i.e., no effect levels) in ambi-
ent media, 2) existing levels in unpolluted ambient media (natural back-
ground), and 3) maximum concentrations safe for limited duration exposures.
These concentrations are the ambient level goals and emission level goals
required in environmental assessment to relate effluent chemical charac-
teristics to their potential environmental impacts.  Goals based on best
available technology are planned but have not been addressed in the develop-
ment of MEGs to date.
     Ambient level goals (i.e., maximum concentrations in ambient media)
include estimated permissible concentrations (EPCs) based on potential ecologi-
cal effects or on predicted toxic levels for man.   EPCs describe levels of
chemicals believed to be safe for continuous exposure over a lifetime.  Exist-
ing or proposed ambient standards and guidelines serve as EPCs for regulated
(or soon to be regulated) chemicals.  EPCs for chemicals not addressed by
Federal guidelines are derived from models that utilize available toxic effects
information.  Oncogenic and teratogenic properties are reflected in a distinct
set of EPCs recognizing that the concept of threshold (no-effect level) may
not apply to chemicals that are potential carcinogens or teratogens.
     Three alternative emission level goals are defined—values describing
minimum acute toxicity effluent concentrations, emission goals based on ambi-

-------
ent level goals, and goals based on elimination of discharge.   Minimum acute
toxicity effluent (MATE) values describe maximum concentrations of chemicals
in the discharge stream believed to be safe for short-term exposure (i.e.,
effects attributable to acute exposure will be minimal).   MATE values are
predicted on the basis of available data pertinent to human health effects or
ecological effects.   MATEs as emission level goals apply to undiluted dis-
charge streams.   Short-term exposures to discharges for which specific chemi-
cal component levels do not exceed their prescribed MATE values are not pre-
dicted (on the basis of the information available) to cause irreversible human
health problems or ecological effects.  The acceptability of each stream
component may be assessed by comparing the discharge concentration with the
component's MATE value.  (This approach is described fully in Reference 3.)
Potential interactions among chemicals are not documented sufficiently to
allow MEGs to properly account for possible synergistic effects.  Thus, cau-
tion should be exercised in applying MATE values to complex effluents.  Bio-
assay data coupled with a MEGs analysis provide a better screening approach
for complex effluents.
     The most stringent ambient level goal for a chemical in a given medium
may be multiplied by a dilution factor to provide an alternative emission
level goal for each discharge component.  A dilution factor describes the
extent of dilution expected.  It is the ratio of the concentration of a pol-
lutant in a discharge stream to the level of the chemical in the ambient
receiving medium.  In practice, depending upo^ the extent of dilution, emis-
sion level goals based on ambient level goals may be more or less stringent
than the MATE values.
     Natural background levels may also serve as emission level goals when a
dilution factor is applied.  Although natural background levels for chemicals
in air, water, or soil vary with site, season, and meteorological conditions,
an attempt is made to specify levels that indicate naturally occurring con-
centration extremes.  Natural background levels are also used to ascertain
whether model derived ambient goals are unreasonably stringent.  Ambient  level
goals should not be lower than natural background levels for any chemical.
     Summarized below are several important practical needs and requirements
associated with establishing goals for environmental assessment.  The MEGs
methodology was developed with these considerations Jn mind.
     1.   Goals must not conflict with existing Federal standards and guide-
lines.

-------
     2.    In the absence of reliably documented "no effect" levels, estimated
safe levels derived from models should be conservative.
     3.    The objective is to set goals—not regulations.
     4.    For use in the environmental assessment program, it is desirable to
have for each chemical a single value goal of each type (i.e., a health based
value for each medium and an ecology based value for each medium).
     5.    Worst case assumptions should be applied in employing available
data, i.e., most conservative values should be used when discrepancies arise.
     6.    Organization of the chemical MEGs should allow systematic utiliza-
tion.  A consistent format is required; a tiered organization is desirable.
     7.    Provision is needed for evaluating model derived goals to determine
if they are reasonable in light of all available information.  An override
mechanism should be possible if the system produces unacceptable goals.
     8.    The overall format for presentation of goals should allow direct
comparison of existing and projected "best available technology" controlled
discharges with emission goals having environmental significance.
     9.    A method is needed for classifying pollutants to get comprehensive
coverage without having to individually consider millions of compounds.
     10.  A procedure is needed for quantifying relative toxicity of classes
of compounds as well as individual compounds to allow a "most-toxic-first"
ordering.
     11.  A uniform approach in applying existing health and ecological effects
data is needed as well as a means for directly delineating health/ ecological
effects data gaps.
     12.  A wide variety of potential adverse effects including oncogenic and
teratogenic effects must be reflected in the goals.
     13.  Sufficient information to indicate the basis for alternative goals
should be provided.
2.2  BACKGROUND INFORMATION SUMMARIES AND MEG CHARTS
     Background information summaries and corresponding MEG charts are pre-
pared for each compound or group of compounds on the MEGs master list.  The
summaries supply the information that serves as the basis for EPCs and MATE
values specified.  Data relating to chemical and physical properties, occur-
rence, related compounds, and associated toxic effects and ecological effects
are summarized.  Federal guidelines associated with each pollutant are indi-

-------
cated as well.   The equations used to calculate EPCs and MATE values are also
presented in the background information summaries.   Each summary occupies a
single page and appears opposite the corresponding MEG chart.  Types of infor-
mation provided in background information summaries are listed in Table 1.
     MEG charts are designed to display the numerical emission level goals and
ambient level goals.  Each MEG chart addresses a single compound or a group of
compounds that is treated collectively in a single background information
summary.  The preferred name of the chemical or group of chemicals addressed
and the identification number is supplied in bold letters in the upper right
                                          3
hand corner of each chart.  Units are ug/m  , ug/L, or ug/g as indicated in the
left hand column.  MEG values for use in environmental assessment appear in
the various columns on the MEG charts.
     To illustrate the format for presentation of MEGs, the background infor-
mation summary and MEG chart for toluene are shown in Figures 1 and 2, res-
pectively.
2.2.1  EMISSION LEVEL GOALS
     Emission level goals are displayed in  the top half of the MEGs chart
(Figure 2).  Any of three types of emission level goals based on ambient
factors may be supplied for a given chemical.  The minimum acute toxicity
effluent (MATE) values are based on either  health effects or ecological effects.
Emission level goals based on ambient level goals also reflect health or
ecological effects.  The  values listed are  the most  restrictive levels selected
from the Ambient Level Goals (lower) portion of the  chart.   Site specific
dilution factors must be  applied to ambient goals to translate the values into

provided to display natural background concentrations.  These values also
require multiplication by dilution factors  to yield  emission level goals.
Footnotes  clarify the nature of data  supplied under  EOD.  The values represent
highest reported rural concentrations unless otherwise indicated.  Technology
based goals have not been addressed yet, thus no values appear in the upper
left-hand  column of the MEG charts.
2.2.2  AMBIENT LEVEL GOALS
     Three types of ambient level goals are displayed in the lower  half of the
MEG chart  to allow  comparison of different  types of  MEGs for a given pollutant

NATURAL OCCURRENCE. CHARACTERISTICS. ASSOCIATED COMPOUNDS:

    Toluene Is a constituent of coal tar; it 1s generally associated with benzene and xylene.  Rural concen-
 tration  in air Is reported as 3.0 to 18.2 ppbc (0.4  to  2.6 ppb, or 1,5 to 9.8 ug/o3) (ref. 2).
    Odor  recognition level is reported as 1.03 to 140 ug/m3 (0.27 to 37 ppto) (ref. 3) and  the odor threshold
 level, 2. 14 ppm (3 mg/m )  (ref. n).  Toluene participates to a limited extent in photooxidation reactions (ref.  3).
    Toluene has been found in samples of U.S. drinking water supplies in concentrations  of 11 ug/t (ref.  4).
TOXIC PROPERTIES. HEALTH EFFECTS:

   Acute poisoning may result from exposure to high concentrations of toluene; a narcotic effect is produced.  Human
death has resulted from exposure to 10,000 ppm (ref. 7).  Toluene is more acutely toxic than benzene;  however, severe
blood disorders  of the type associated with benzene are not reported.  Inhalation of 100 ppm has resulted  in
psychological  effects and 200 ppm has affected the central nervous system in humans (ref. 8).  Irritative  effects
to eyes, raucous  membranes, and the upper respiratory tract have resulted from exposure to 200 to 500 pom (ref. 12).
Toluene may be absorbed through the skin as well as by inhalation (ref.  12), although the inhalation route is  far
more important.  There is evidence to indicate that at equilibrium, the average toluene concentration per liter of
blood is 2.4 rag  for each 100 pom toluene in the envlroiwental air (ref.  13).  The biological half-.ife for toluene
is reported to be 0.083 days (ref. 14).
   LOSO (oral, rat):  5,000 mg/kg.  LCLo (inhalation, rat):  4,000 ppm for  4 hours.

   Aquatic toxicity:  TLm 96:  100-10 ppm (ref. 8).  Concentrations of 0.25 mg/i can cause tainting of fish flesh
(ref. 15).
   Phytotoxicity:  exposure for 35 minutes to 50 ppm of ozonated toluene produced a bronze color on.pinto  beans
(ref. 21)., 50 ppm is equivalent to 188 ing/m .  24 hr. exposure corrected concentration is 188 x 10  x .35/14*0 *
4,570 ug/nT5 (1.2 ppm).
REGULATORY ACTIONS. STANDARDS. CRITERIA. RECOGNITION. CANDIDATE STATUS FOR SPECIFIC REGULATION;

    TUV » 375 mg/m3 (100 pom).  Toluene is on EPA's Consent Decree Priority III  List.

    Toluene is the subject of a NIOSH Criteria Document.   The NIOSH recommendation for occupational exposure
 to  toluene is 100 ppm as an 8-hour per work day time-weighted average.  A ceiling value of 200 ppm is
 recoownded (ref. 12).

    Toluene Is on the First Priority Chemicals List of Chemical  Industry Institute of  Toxicology.

rials.  Federal standards or criteria, based on health or based on ecological
effects, are specified in the two left hand columns.   MEGs called estimated
permissible concentrations (EPCs), also based on health effects or on ecolog-
ical effects, are supplied for compounds not addressed by Federal guidelines.
MEG values appear in the far right column for compounds exhibiting significant
oncogenic or teratogenic properties.  Because certain compounds are toxic as
well as oncogenic or teratogenic, values may appear in two or three of the EPC
columns.  In general, EPCs are not specified for a particular medium if
Federal guidelines apply.
2.3  SELECTION CRITERIA FOR THE MASTER LIST OF CHEMICALS TO BE ADDRESSED
     BY MEGs
     Chemicals included in the MEGs master list were selected on the basis of
the following criteria:
     1.   Any chemical or class of chemicals associated with fossil fuels
processes should be included.
     2.   Chemicals addressed by existing Federal guidelines or for which
there are available toxicity data (TL\r, LD5Q, evidence of carcinogenicity,
etc.) should be included if they are representative of a class of chemicals
associated with fossil fuels processes.
     3.   Chemicals known to be present as pollutants in the environment or
that are highly toxic may be included even if they are not associated with
fossil fuels.
     The third criterion was applied in a few cases only, so the major focus
of the list remains the fossil fuels pollutants.  Several chlorinated hydro-
carbons (including PCBs) were included in an effort to provide worst case
coverage for important categories.  All Consent Decree Pollutants are included
in the list.
2.4  ORGANIZATION BY CHEMICAL CATEGORIES AND IDENTIFICATION NUMBERS
     To reduce nomenclature problems and to organize compounds into struc-
turally and toxicologically similar groups, a chemical category system has
been  used throughout the MEGs report.  Pollutants to be addressed by MEGs are
organized into categories on the basis of their chemical structure.  Twenty-
six major organic categories have been established, and within each category
two or more subcategories are specified.  A listing of these categories and
subcategories  is provided in Appendix B along with a discussion of the chemi-
                                        10

-------
cal characteristics of the compounds assigned to each.   Except for
Category 26, the category list and descriptions are basically the same as
those presented in Volume I,  Appendix A.   (See explanation in Section 3.2 in
this volume.)  Several new subcategories  are specified.
     Identification numbers have been assigned to each MEG compound.   These
numbers indicate the category and subcategory of the chemical as well as its
position within the subcategory.  Identification numbers are discussed in more
detail in Section 3.1.
     A complete listing of the organic chemicals ordered by MEG ID number is
given in Appendix C, this volume.  This listing supersedes the master list of
organic chemicals presented in Volume I,  Appendix B.   The background
information summaries and MEG charts in Volumes III and IV, the tabulated MATE
values in Appendix D (this volume), and the listing of Hazard Potential  Values
in Appendix E (this volume) are ordered by the MEG ID numbers.
     There are several reasons for organizing the MEGs listings by ID numbers
(hence by categories).  The categorical approach based on functional  groups
allows the user to consider MEGs for a group of related compounds or for a
single specific chemical.  In the absence of toxicity data to characterize a
specific chemical of interest, it is often reasonable to use information
available for a different compound of similar structure as a surrogate to
estimate the needed MEG values.  (Without an assigned MEG value there would be
no way to assess the relative contribution of that compound in terms of the
potential environmental impact of the stream.)  Also, the results of chemical
analysis frequently do not distinguish between several  isomers or structurally
similar compounds, so a categorized approach is beneficial in selecting the
best data to be used in an assessment procedure.
     For users unfamiliar with the categories used for organizing MEG com-
pounds, an alphabetical index of preferred names and synonyms for organics is
provided in Appendix F, this volume.  A molecular formula index is also included.
It is expected that regular users of the  MEGs will become familiar with the
category system and will find it simpler to find information on a given com-
pound by going directly to the appropriate category to locate the compound
rather than seeking its ID number from the alphabetical  index.
2.5  MODELS TO GENERATE MEGS
     Models that are used to generate MEGs for chemical  pollutants are
described in detail in Sections 5 and 6 of the 1977 MEGs report, Volume I.
                                        11

-------
Tables 2 and 3 list the equations recommended for calculating EPCs and MATEs
and indicate the particular section in Volume I where the model is discussed.
Equations for calculating MEGs based on health effects are given in Table 2.
Table 3 supplies the equations to calculate values based on ecological effects.
     Definitions and brief explanations of some of the terms associated with
the MEG models are provided below:
                                 A
     Threshold Limit Values (TLVs ) are levels of contaminants considered safe
for workplace atmosphere, as recommended by the American Conference of Govern-
mental Industrial Hygienists (ACGIH).  Time-weighted averages for exposure
                                                                 ^
durations of ten hours per day or 40 hours per week are specified for more
than 500 chemicals.4
     National Institute of Occupational Safety and Health (NIOSH) Recommenda-
tions also apply to occupational exposure limits for chemical contaminants.
                                               ®
These recommendations are analogous to the TLVs  but frequently are more
stringent.  Ceiling values as well as time-weighted exposure limits are recom-
mended.  More than 75 NIOSH criteria documents addressing one or more specific
chemicals are currently available.  These criteria documents serve as the
bases for the NIOSH recommendations.
     Genotoxic Chemicals include carcinogens,, teratogens, and mutagens.  The
term means toxic to genetic material.
     LD(50) is the lethal dose to 50 percent of an animal population tested.
The LDj-Q is generally reported as tag of toxicant per kg of animal body weight.
Oral rat data are frequently reported and used most often in the MEGs models,
although other route/species combinations are substituted if oral rat data  are
unavailable.  The lowest published lethal dose is substituted in the absence
of more statistically reliable lethal dose data.
     Adjusted Ordering Numbers used in the HEGs methodology are derived from
the ordering numbers developed in the 1976 EPA report, An Ordering of the
NIOSH Suspected Carcinogens List Based Only on Data Contained iji the List.

               AH-     .  nn   _    Ordering number

                                   or teratogenic effects
Adjusted ordering numbers increase with carcinogenic (or teratogenic) potency
and thereby serve as an index to rank chemicals that are potentially geno-
toxic.  The numbers have no physical meaning since they are obtained using  an
arbitrary weighting system.  They are used in MEGs because they allow ranking
                                        12

of carcinogens and teratogens on the basis of information that is readily
obtainable for a large number of chemicals.   Adjusted ordering numbers are
influenced primarily by (1) the lowest effective dosage reported, and (2) animal
species giving positive tests.    Adjusted ordering numbers for organic sus-
pected carcinogens currently addressed by MEGs range from unity up to about
three million.  (See Section 4.3 for a discussion of adjusted ordering numbers
for organic chemicals addressed in Reference 2.)
     Carcinogenic Potential is indicated by the ability of a chemical to
produce tumors in animals or man at a rate that is significant above back-
ground tumor incidence.
     Teratogenic Potential pertains to the ability of a chemical to produce
effects in the offspring after the pregnant female is exposed.  Many chemicals
that are teratogenic are also suspected carcinogens.
     Threshold Limit Median (TLm) describes the lethal concentration of a
pollutant to 50 percent of a tested aquatic species population.  TLms are
generally expressed in mg/L.  Exposure durations may be 24, 48, or 96 hours;
most frequently 96-hour values are reported.  Values vary depending on species
tested, the test type (i.e., static or flowthrough bioassay), and other con-
ditions such as pH or water hardness.  The TLm reported for the most sensitive
species is used in the equations to derive MEGs.
     Application Factor is the ratio between the safe and lethal concentration
of a chemical.  The factor is almost always within the range 0.1 to 0.01.  If
Tim and application factor are established for a chemical, the safe concentra-
tion for a given species tested is easily calculated.

       Safe level for aquatic species = Application factor x TLm

     Tainting of Fish, evident as objectionable taste, odor, or color, may
occur when the fish are exposed to certain chemicals.  Generally, the effect
is reversible if the fish are removed to clean water.
2.6  HAZARD POTENTIAL VALUES
     Since available resources for chemical analysis are noninfinite, it  is
important that efforts be focused on chemicals that are potentially the most
dangerous.  Thus, a basic need in environmental assessment is a method for
ranking chemicals on the basis of their potential environmental  impact taking
into consideration a wide variety of effects.  To meet this need a systematic
                                        16

-------
method was described in Volume I  for the calculation of Hazard Potential
Values based on MEGs reflecting potential effects on human health.   The equa-
tion used to derived these Hazard Potential Values is given below:
                         N = 2aa'A + 4bB
where N is the hazard potential value;
      A is determined by the toxicity based EPC (health effects) for air; and
      B is based on the "zero threshold" EPC for air.  ("Zero threshold"
chemicals include potential carcinogens and teratogens.)
      a, a', and b are weighting factors.
      Values assigned are as follows:
     a = 1 if genotoxic properties are indicated (i.e., B is available).
     a = 2 if genotoxic poperties are not indicated (B missing).
     a'= 1.25 if cumulative or chronic effects are indicated.
     a'= 1.0 if only acute effects are documented.
     b = 1 if toxic potential data are available (A is available).
     b = 1.5 if toxic potential data are unavailable (A missing).
     The assignments of values for A and B are indicated in Table 3.

     Updated Hazard Potential Values calculated for organic MEG compounds are
given in Appendix E of this volume.   This listing supersedes the numbers given
for organics in Appendix D of Volume I.
     The compounds receiving the highest Hazard Potential Values (in the
equation above) have been assigned hazard indicators which appear in the upper
right-hand corner of the MEG charts in Volumes II, III and IV.    XXX denotes
the compounds of greatest concern (Hazard Potential Values S 25); XX indicates
the next highest level of concern (Hazard Potential Value 19 to 25), and X
denotes moderate concern (Hazard Potential Value 13 to 19).  A total of 68
organic compounds are assigned indicators.

                                   SECTION 3
                MODIFICATIONS TO THE ORIGINAL MEGs METHODOLOGY

     The system introduced in Reference 1 for calculating and presenting MEGs
has been applied in Volumes III and IV and in this volume.   A few minor modifi-
cations in the methodology have been adopted.   These changes are:   1) ID
numbers have been assigned to each MEG compound and now serve as a means for
ordering the chemicals in various listings; 2) one MEG category, Category 26,
formerly Organometallics, has been changed to address Organophosphorus Com-
pounds; 3) the land model for calculating EPCs and MATEs has been altered;
4) in an effort to supply reasonable goals for as many compounds as possible,
in some cases analogies between similar compounds are drawn and data extrap-
olated to yield MEGs for compounds otherwise without quantitative goals (this
is done only for certain categories and only when there is clear evidence that
the analogy is warranted; 5) the system for handling references in the back-
ground information summaries has been improved.
     The subsections that follow address each of these changes as well as
other less significant refinements.
3.1  IDENTIFICATION NUMBERS
     Six-digit identification numbers have been assigned to each organic MEG
compound.  These ID numbers indicate the category, subcategory, and position
within the subcategory for any chemical.  Thus, structurally similar compounds
will be assigned similar numbers.  The association of structurally similar
compounds is a powerful tool in environmental assessment, especially in the
absence of complete profile data for many substances.  The use of MEG ID
numbers augments the association of data for related chemicals.  The method
for assignment of the 6-cipher numbers is illustrated in Figure 3.

-------
     The information contained in each of the six digits in the organic MEG
compound identification numbers are explained below:
Category Number
     The first two digits (reading from left to right) of the ID number indi-
cate the MEGs category number.   A total of 26 organic categories are defined.
(See Appendix B this volume.)  These categories are established to group
together compounds with certain functional groups (e.g., Alcohols-Category 5,
Amines-Category 10) or that are structurally similar (e.g., Benzene and Substi-
tuted Benzene Hydrocarbons-Category 15).
Subcategory
     The third digit of the ID number indicates the subcategory to which the
compound belongs.   Each category is divided into two or more subcategories
designated A, B, C...  in an effort to associate compounds of a homologous
series or that are otherwise related structurally.   For example, aromatic and
aliphatic compounds with a common functional group may comprise separate
subcategories within a functional group category.  The degree of substitution
on a hydrocarbon chain or on a benzene ring distinguishes the subcategories of
certain groups.
Compound Number
     The last three digits of the ID number comprise the compound number.
Compounds of each subcategory are arranged in increasing order of complexity,
and compound numbers are assigned to reflect the position of a given compound
relative to others within a subcategory.   The numbers 020, 040, 060...980 are
used, the first compound (i.e., the simplest or lowest molecular weight com-
pound) of any subcategory being assigned the lowest number.  (The odd decades,
010, 030, 050... are generally reserved for substances that may need to be
added to the MEGs list at a later date.  Only a few of these numbers are
currently used.)
Subspecies Number
     The last digit of the ID number (if a nonzero number) indicates the
subspecies number.  Subspecies arise when two or more compounds are addressed
collectively in a single background information summary and MEG chart.   Sub-
species are specific compounds that are closely related and that can be classi-
                                        19

-------
fied with a parent structure, i.e., the substance whose name appears on the
MEG chart.   The identification number for each subspecies will  be the same as
the number for the parent chemical, except that the last digit  of the compound
number will be a nonzero integer.   Subspecies numbers reflect increasing
complexity among the compounds listed under a give parent structure.  The ID
numbers assigned to the pentanes illustrate the subspecies concept.   Pentanes
are included in the MEGs master list in Category I (Aliphatic Hydrocarbons),
Subcategory A (Alkanes and Cyclic Alkanes).  The ID numbers are listed below.
                         Pentanes        01A100
                                                                 •\

                         Neopentane      01A103
     Data pertaining to the pentanes are presented on a single  background
information summary entitled PENTANES.   One MEG chart is supplied, and the MEG
values shown may be applied to an individual subspecies, or to  the group
collectively.
     The system for assigning the ID numbers has been designed to allow for
expansion of the MEGs master list.  New chemicals may be introduced at almost
any location within any subcategory.  Also, up to nine subspecies may be
listed with each parent compound.
     A related system for assigning MEG ID numbers for inorganics is also pro-
posed for use in subsequent MEGs volumes.  For inorganics each parent element
ic assigned a category number.  The remaining digits of the number indicate
the elements combined with the parent element to comprise a specific chemical
3.2  THE REVISED LIST OF ORGANICS
     The only major change in the MEGs master list of organic compounds involves
Category 26, originally Organometallics.  All the compounds previously in this
category have been reassigned to the category of the parent element.  Alkyl
mercury, for example, is no longer listed in Category 26 but in Category 83
with other mercury compounds of environmental importance.  In the revised
master list, Category 26 is comprised of organophosphorus compounds.  This
class of compounds was not included in the original master list.
     The MEGs master list as presented in Volume I has been revised to correct
errors and to better organize the original list of compounds.  Certain of the
original MEGs categories have been resolved into subcategories to describe
more clearly the compounds included.  A few new compounds were added to the
                                        20

-------
list because of their designation as Priority Pollutants in the Consent Decree.
All compounds that are moved to a different category or added to the MEGs
master list since November 1977 are indicated in Table 5.   The revised master
list of organics is given in Appendix C, this volume.
     All  the changes in the MEGs master list have been made in an effort to
group together structurally and toxicologically similar compounds and to
improve specificity within subcategories.
3.3  LEACHING MODEL REVISION
     One of the conclusions mentioned in Volume I of the MEGs report is that
the EPCs and MATE values specified for land or solid waste, respectively,
appear too stringent.  Natural background levels, available for a few com-
pounds, were likely to be higher than the model derived EPC.   To remedy this
problem the original model to generate land or solid waste MEGs has been
revised to incorporate a dilution factor.   The rationale behind the change
follows.
     The original leaching model used for relating acceptable levels of con-
taminants in water to goals in soil or in solid waste incorporated the assump-
tions that 1) all contaminants in 1 kg of soil (or solid waste for MATE model)
would be leached by 2 liters of water; and 2) the resulting concentration of
the contaminant in the leachate should not exceed the value of the water EPC
(or MATE value if leachate is from solid waste).
     The equations for the models introduced in Volume I are given below.  The
subscripts indicate land (L), water (W), health (H), and ecology (E).  EPCs
and MATEs for solid waste are in ug/g, and values for water are in pg/L.
     EPCLH   =  0.002 x EPCWH
     EPCL£   =  0.002 x EPCWE
     MATELH  =  0.002 x MATEWH
     MATELE  =  0.002 x MATEWE
     The original model thus assumes that man and aquatic organisms may be
exposed to the concentrated leachate, a questionable assumption.  In actu-
ality, the only way leachate from solid waste will affect human life or aquatic
life is by contaminating existing water supplies or habitats which may be
assumed to be pure, or at least contaminated to a lesser degree than the
leachate itself.  Hence, a dilution factor is needed in the model.
                                        21

-------
     For the revised MEG land model, an arbitrary dilution factor of 100 is
incorporated in the model described above.   The revision implies that any
leachate will be diluted by a factor of 100 upon entering a body of water that
supports aquatic life or that might be used for human consumption.   This means
that the contaminant concentrations in the undiluted leachate (a volume mass
equal to twice the mass of the solid material) may be 100 times the acceptable
level of the contaminant in the body of water.  An alternate interpretation of
the model could involve a larger volume of leachate to effect complete extrac-
tion of toxic materials.  Subsequent dilution other than 1:100 would be assumed
in this case.  The ultimate dispersal  of leached toxicant in water of mass
200 times that of the initial solid material results in either interpretation.
     The revised model is still conservative, but it is more consistent with a
real leaching/ dilution/ exposure scenario.   The revised equations are as
follows:
     EPCLH   =  0.2 x EPCWH
     EPCLE   =  0.2 x EPCWE
     MATELH  =  0.2 x MATEWH
     MATEL£  =  0.2 x MATEWE
3.4  ASSIGNMENT OF EPCs AND MATE VALUES IN THE ABSENCE OF EMPIRICAL DATA
     In order to calculate MEGs for a compound, the original methodology
                                           IB
required certain empirical data such as TLv  or LD5Q for the compound.   If
such data were unavailable, MEG values were not specified.   In Volumes III and
IV an effort has been made to include as many values on the MEG charts as
possible including, for certain categories,  values derived by analogy with
similar structures.  The reasoning behind this attempt to assign additional
MEGs is that it permits more extensive coverage for preliminary environmental
assessment efforts.  All MEG values based on surrogate data are derived very
cautiously and are carefully documented.
     By grouping similar compounds into categories and subcategories, many
patterns relating to toxicity have become apparent.   For certain homologous
series, for example, prediction of toxic potential for an undocumented com-
pound is feasible on the basis of data from other members of the series.   For
certain compounds for which toxicological data are unavailable, MEGs are
specified in Volumes III and IV on the basis of information for related com-
pounds.  If there is evidence that extrapolation of data from structurally
related compounds is not appropriate (in the polycyclics, for example), then
                                        23

-------
this approach is not used.   For all cases in which surrogate data serve as the
basis for MEG values, the specific rationale behind the extrapolation is
indicated in the background information summary.   Surrogate values are also
indicated on the MEG charts.
3.5  INFORMATION SUMMARY REFERENCES
     The system used to reference information items contained in the back-
ground information summaries in Volumes III and IV differs from the system for
references used in Volume II.  In the 1979 report, references are compiled
independently for each subcategory, and the reference list is supplied follow-
ing all the background information summaries and MEG charts for the subcate-
gory.
     This new system allows the user to ascertain quickly if a given reference
has been used in preparation of the summaries for a subcategory.  If a signifi-
cant reference is overlooked, it should be brought to the attention of the EPA
project officer so that future updates can take advantage of the new source of
information.
3.6  CANDIDATE LIST
     A candidate list of organic compounds to be addressed by MEGs in the
future has been compiled.  This list is presented in Appendix C following the
master list of organics.
     In the candidate list, an effort has been made to assign chemicals to the
appropriate MEGs category.   The list includes several types of compounds that
were not previously addressed by MEGs, and tentative category assignments were
made.  The strategy for these assignments is summarized in the statements that
follow:
     1.   Candidate compounds are assigned to the MEGs category which most
closely describes the chemical structurally.
     2.   Where more than one functional group is present in a structure, the
compound is assigned to a category on the basis of the most reactive func-
tional group.  Prediction of the most reactive group is often difficult and
may  involve a "best guess."
     3.   For multifunctional compounds, assignment to a MEGs category may
involve consideration of applicable, analytical techniques.  For example,
solvent extraction of complex effluents results in a series of fractions that
may  be described as acid, basic, or neutral.  Compounds that elute in these
                                        24

-------
fractions are influenced by functional groups, molecular weight, configura-
tion, aromaticity, etc.   The fraction in which a compound is expected to elute
is considered in making the the category assignment.   Again a "best guess" is
frequently involved.
     4.    Peroxides are grouped with glycols and epoxides in Category 6.
     5.    A large number of alcohols with ether functions (methoxy, ethoxy,
etc.) are included with alcohols in Category 5.
     6.    Compounds with both hydroxy and keto functions are included with
aldehydes and ketones in Category 7.
     7.    Aliphatic nitro compounds are added in Category 9.
     8.    Phenolic compounds with ether functions (methoxy, ethoxy, etc.) are
included with phenols in Category 18.
3.7  GRAPHICAL SUMMARIES OF MEGs BY CATEGORY
     Appendix G of this report presents graphical summaries by subcategory of
the EPCs and MATEs for all organic chemicals addressed in MEGs Volumes III and
IV.  The graphs show the ranges in the MEG values based on health and based on
ecology for compounds in each subcategory.  The point values for specific
chemicals are indicated.  Ecology based values may be readily compared with
health based values on the graphs.  Goals based on carcinogenic potential are
flagged so that subcategories with a number of chemicals classified as sus-
pected carcinogens are evident.   The summaries are very useful for comparing
relative toxicities of the various MEGs categories.

                           ORGANIC MEGs—CONCLUSIONS

     Background information summaries and MEG charts for organic compounds are
presented in Reference 2.   Conclusions regarding the MEGs for these compounds
considered collectively are discussed in this section.
4.1  EXTENT OF COVERAGE AND DATA GAPS
     To date 319 background information summaries and MEG charts have been
prepared addressing a total of 586 organic chemicals.  Of the 319 MEG charts,
48 remain without calculated MEG values because of inadequate information.
For these chemicals, it was deemed inappropriate to rely on information perti-
nent to related compounds.  Natural background levels are indicated on 12 of
the charts otherwise without MEG values.  The natural background at least
indicates a lower limit that can be used as a control goal.
     Table 6 gives a summary by category of the types of MEG specified for the
organic compounds.  It is evident from this summary that while it is possible
to estimate MEGs for many compounds major data gaps exist for chemicals in
several categories.  Of particular significance to synfuels assessments are
the data gaps in Categories 21, 22, and 24 addressing polycyclics.  Ecology
data for these chemicals are very sparse.
     More than 85 percent of the organic chemicals addressed in background
information summaries are assigned MEGs for air and water based on health
effects.  These MEGs reflect either acute or chronic toxicity, or they may be
based on oncogenic or teratogenic properties.  Although long term carcino-
genicity studies in animals have been performed for many polycyclic compounds,
acute animal toxicity data is reported for only a few of these structures.
There is virtually no human toxicity data for these chemicals, and no cor-
relations are established between carcinogenic potential and acute toxicity.
For chemicals not shown to be active tumor promoters or carcinogens, it is
possible that low MEG values are warranted on the basis of acute toxic prop-
erties, but the required data to support acute toxicity MEGs are seldom reported
from the carcinogenicity studies.
     Empirical data to calculate MEGs for air based on ecological effects are
available for relatively few organic chemicals.  Only 28 charts list ecology
based air MEGs, and almost all of these are for aliphatic hydrocarbons.  Of
                                        26

these values, only the ones for ethylene are substantially lower than the
corresponding MEGs reflecting health or genotoxic effects.   In spite of the
apparent tendency for health based MEGs to be more stringent, the lack of
available vegetation effects data points up a need for further research.
Effects of air pollutants on vegetation are not predictable on the basis of
chemical structure.   Thus research projects to secure effects data for a broad
range of chemicals on various sensitive species will be required before sub-
stantial numbers of ecology based air MEGs can be supplied.  The MEGs models
prescribed in the current methodology to calculate EPCs and MATEs from the
lowest effective concentration are probably adequate for use with the existing
data base.   Necessary data for complex models are not available for a large
number of chemicals.  There is little standardization in the literature for
reporting effects of chemicals on vegetation.
     Aquatic toxicity data are available for approximately 40 percent of the
organics addressed.   For several categories, however, there are no data to
indicate aquatic toxicity.  Azo compounds (Category 11) and nitrosamines
(Category 12) comprise two important categories for which aquatic toxicity has
not been characterized.
     Natural background concentrations are unavailable for many organic chemi-
cal categories.  As indicated in Table 6, more air values than water values
are supplied.  Levels of organics in soils are not documented except for a
very few chemicals.
     Tables 7 through 10 list MEG ID numbers 1'or compounds according to their
EPC values.  Given  in each column on the tables are the ID numbers for com-
pounds assigned EPCs within the range indicated.  Health based air and water
values are addressed in Tables 7 and 8, respectively.  Ecology based values
for air and water are shown in Tables 9 and 10, respectively.  Land values
based on health and based on ecology are derived directly from water data
except that land values for gases are not calculated.
4.2  VERSATILITY PROVIDED BY PRESENTATION FORMATS
     The several formats for presentation of MEGs data were selected in an
effort to produce a document that would be useful for data analysis in
environmental assessment.  In addition to the single page background infor-
mation summaries and MEG charts, several listings are compiled, each supplying
a different level of information.  The referenced one-page background infor-
                                        28

(nation summaries supply the most detail.   MEG charts display the more strin-
gent MEG values resulting from calculations appearing on the background infor-
mation summaries.   Charts are especially useful for comparing MEG values of
different types for a given chemical.  They also indicate by the presence or
absence of MEG values the extent of available information for a given com-
pound.  Tabulated MATE values facilitate comparison of the MEGs for different
chemicals.  Although the basis for each value is not indicated in the tabu-
lations, and this has become a major criticism,  it is desirable to have the
listing uncluttered for use with the source analysis model (SAM).   Users of
the tabulated MATE values should be aware that the basis for each number can
be determined from the background information summary for the chemical of
interest.
     Hazard potential values are tabulated to allow ranking among the various
chemicals.  Unlike the EPCs and MATEs, no physical meaning should be attached
to the hazard potential values.  They are for ranking chemicals only.  As with
the tabulated MATE values, the bases for the numbers cannot be ascertained
from the listing of the numbers.
     Graphical summaries of the MEG values provide another means for comparing
environmental severity of different compounds.  The graphical summaries allow
comparison of ranges of values within a category and also facilitate inter-
category comparisons.
     Each format type is designed for a different application.  Information
has been extracted from the background information summaries to supply all the
numbers in the various listings.
4.3  RANKING ORGANIC COMPOUNDS USING THE MEGs METHODOLOGY
     As pointed out in Section 2.1, one consideration in developing the MEGs
methodology was the need for a procedure to allow a "most toxic first" order-
ing among chemicals.  The Hazard Potential Values were designed to meet this
requirement.
     A summary listing of the 68 organic substances receiving Hazard Indi-
cators, X, XX, and XXX, follows the table of hazard potential values in
Appendix E.  Forty nine chemicals are assigned a single "X" rating, 13 are
assigned "XX," and 6 are assigned "XXX."  All of the six compounds receiving
the highest hazard indicators are suspected carcinogens.  One of these, 1,1-
dichloromethyl ether, is designated a human carcinogen by the ACGIH.  Five of
the six compounds of highest concern are polycyclic organic hydrocarbons.
                                        32

-------
     Adjusted ordering numbers serve as the basis for the MEG values for
suspected carcinogens and teratogens.   In general, these values may be used to
rank the potency of suspected genotoxic chemicals.  Because the adjusted
ordering numbers are influenced so strongly by the lowest reported effective
dose (almost always a dosage in a laboratory animal species), certain chemi-
cals recognized to cause cancer in man are not assigned high adjusted ordering
numbers since very low effective dosages are not documented.  Evidence of
human carcinogenicity should be considered in ranking chemicals but the absence
of quantitative data frequently precludes this.   The adjusted ordering numbers
serve reasonably well for their intended purpose, but several exceptions must
be acknowledged in the rankings based only on adjusted ordering numbers.
Listed in Table 11 are the adjusted ordering numbers for organic suspected
carcinogens and teratogens currently addressed by MEGs.  It should be noted
that MEG values for some of the chemicals in Table 11 are based on data other
                                          ®
than adjusted ordering numbers (e.g., TLVs  or NIOSH recommendations).
4.4  PHASE I
     This volume together with MEGs Volumes I through IV constitute Phase I of
MEGs development.  There exist many shortcomings in the methodology and in its
application.  Enough is accomplished in these volumes, however, to guide
development of MEGs Phase II.
     This concludes Phase I.

                      MEG CATEGORIES FOR ORGANIC CHEMICALS


     The list of organic chemical substances to be addressed by MEGs has been
divided into 26 categories in an effort to organize the list and to facilitate
its use.  Each of the 26 categories is further divided into two or more subcate-
gories, grouping together structurally and toxicologically similar compounds.
A listing of the MEG categories and subcategories for organics is given in
this appendix.  Distinguishing features of the specified categories and the
rationale for compound assignments to the categories are also discussed.

     This listing of categories and subcategories and the category descrip-
tions supersede the organic category titles and descriptions provided in
Appendix A of the 1977 MEGs Report Volume I.*

             DISTINGUISHING FEATURES OF THE MEG ORGANIC CATEGORIES
                    AND RATIONALE FOR COMPOUND ASSIGNMENTS
                      CATEGORY 1:  ALIPHATIC HYDROCARBONS
     Aliphatic hydrocarbons are the simplest of the organic compounds.  They
contain only the elements carbon and hydrogen.   With the exception of the
lower molecular weight compounds, aliphatic hydrocarbons are insoluble in
water.
     Aliphatic hydrocarbons may be either open-chain compounds or cyclic
compounds which resemble open-chain compounds.   Their physical and chemical
properties are influenced by molecular weight,  skeletal structure (straight-
chain, branched or cyclic), and the presence and location of double or
triple bonds.  Aliphatic hydrocarbons, as opposed to aromatic hydrocarbons,
undergo free radical substitution reactions.  Unsaturated aliphatic hydrocar-
bons, i.e., those with double or triple bonds,  undergo additional reac-
tions.
     Category 1 is divided into three subcategories:
A.   Alkanes and Cyclic Alkanes—These compounds have no double bonds.  They
     are non-polar and relatively unreactive.
B.   Alkenes, Cyclic Alkenes, and Dienes—These compounds contain one or more
     double bonds, i.e., carbon atoms joined together by two pairs of elec-
     trons.  Because of the double bonds, these compounds are more reactive
     than alkanes.  They may be weakly polar.
C.   Alkynes—Alkynes are characterized by a triple bond.  A triple bond does
     not react in exactly the same way as a double bond.  Alkynes may be
     reduced to alkenes by the addition of H2.   Another important reaction of
     alkynes is the addition of H20 to form aldehydes or ketones.

                          CATEGORY 2:   ALKYL HALIDES
     Alkyl halides are aliphatic hydrocarbons in which one or more hydrogens
are substituted by chlorine, fluorine, bromine or iodine.
     Category 2 is divided into two subcategories:
A.   Saturated Alkyl Halides—Both simple alkanes and cyclic alkanes contain-
     ing one or more halogens are included in this group.  Such compounds are
     called saturated because they contain no double bonds.
B.   Unsaturated Alkyl Hal ides—Halogenated non-aromatic hydrocarbons contain-
     ing one or more double bonds are included.  Unsaturated alkyl halides are
     more reactive than saturated compounds.
                                     B-7

-------
                              CATEGORY 3:   ETHERS
     Ethers are compounds in which two hydrocarbon moieties are covalently
bonded to one oxygen.   Ethers can be either linear or cyclic.   In linear
ethers the hydrocarbon moieties are unconnected alkyl or aryl  groups.   In
cyclic ethers the oxygen atom is a constituent of a ring structure.   Ethers
are generally mobile liquids with high vapor pressures.   They are weakly polar
and are commonly used as solvents.
     Ethers are not highly reactive.  The ether linkage is quite stable toward
bases, oxidizing agents and reducing agents.  They may oxidize in air, how-
ever, to form peroxides.  Ethers are highly flammable.
     Category 3 is divided into two subcategories:
A.   Noncyclic Aliphatic or Aromatic Ethers—These ethers are of the general
     formula ROR1, ArOR, or ArOAr, where R is any aliphatic group and Ar is
     any aryl (i.e. aromatic) group.
B.   Cyclic Ethers—Cyclic ethers may contain one or more ether functional
     groups within a ring structure.
     Two special kinds of ethers are discussed in separate categories:  furan
and its derivatives are included in Category 24 with the heterocyclic oxygen
compounds; epoxides are included with glycols in Category 6.

                 CATEGORY 4:  HALOGENATED ETHERS AND EPOXIDES
     Halogenated ethers are prepared by dehydration of halogenated alcohols.
Chlorinated ethers are of particular interest and are characterized by substi-
tution of one or more hydrogen atoms by chlorine in the alkyl radical of an
ether.  Most chlorinated ethers are highly toxic, and several chlorinated
ethers are recognized carcinogens.
     Category 4 is divided into two subcategories:
A.   Monohalogenated Ethers and Epoxides—Monohalogenated ethers are ethers in
     which a single halogen atom replaces hydrogen on the aliphatic or aryl
     radical.                                                    r
B.   Pi halogenated and Polyhalogenated Ethers—Pi halogenated and polyhalogenated
     ethers have two or more halogens substituting hydrogen on the aliphatic
     or aryl radical.
                                     B-8

-------
                             CATEGORY 5:  ALCOHOLS
     Alcohols are characterized by the presence of an -OH function called a
hydroxyl group.  They have the general formula ROH where R is an alkyl group.
The hydroxyl function may be attached to a primary, secondary, or tertiary
carbon atom in the R group.  Depending upon the character of the carbon to
which the -OH group is bonded, alcohols may undergo two types of reactions.
These reactions are (1) the removal or substitution of the -OH group, or (2)
the removal or substitution of the hydrogen atom in the OH group.
     Category 5 is divided into three subcategories:
A.   Primary Alcohols--These are compounds in which the hydroxyl is attached
     to a lone carbon or a primary carbon, i.e., a carbon which is bonded to
     only one other carbon atom.
B.   Secondary Alcohols--These alcohols are compounds in which the hydroxyl
     group is attached to a secondary carbon.  A secondary carbon is a carbon
     bonded to two other carbon atoms.
C.   Tertiary Alcohols—These are compounds in which the hydroxyl group is
     attached to a tertiary carbon, ie., a carbon bonded to three other carbon
     atoms.
     Glycols and phenols are two special types of alcohols which are listed in
Categories 6 and 18, respectively.   Glycols are alcohols containing two hydroxyl
groups.   Phenols contain a hydroxyl group as a substituent on a benzene ring.

                        CATEGORY 6:  GLYCOLS, EPOXIDES
     Glycols and epoxides are included in this category.   Two subcategories
are specified:
A-   Glycols—Glycols are alcohols containing two hydroxyl groups.   They are
     sometimes  referred to as diols.   Glycols may be formed by the hydroxy-
     lation of alkenes, the hydrolysis of halides,  the bimolecular reduction
     of carbonyl compounds, and the hydrolysis of epoxides.
B.   Ep_oxJ_des--Epoxides are compounds containing a ring formed by two carbons
     and an oxygen: _Q-C-
                     o'
     Epoxides are ethers, but due to configurational strains they are less
     stable than normal ethers.
          Epoxides are prepared from halohydrins and from the peroxidation of
     carbon-carbon double bonds.  The three-membered carbon-oxygen ring gives
     them distinct chemical properties.   They are readily hydrolyzed to glycols.

                                      B-9

-------
                        CATEGORY 7:  ALDEHYDES, KETONES
                                                          (3
     Aldehydes and ketones contain the functional group   c   called the

carbonyl group.   Due to the common carbonyl functional group the properties of

aldehydes and ketones are similar in many ways.

     Because of the tendency of oxygen to acquire electrons, the carbonyl

group is polarized, leaving it accessible and open to attack by bases.  Addition

reactions are typical.

     Three subcategories are specified.

A.   Aldehydes—Aldehydes are compounds of the general formula R-C-H where R
     may be either an aliphatic or aryl group.  Aldehydes are easily oxidized
     and are usually more reactive toward nucleophilic addition than are
     ketones.                                                0
                                                            >'
B.   Ketones—Ketones are compounds of the general formula  R  V where R and
     R1 may be aliphatic or aryl.  Ketones are oxidized only with difficulty
     and are generally less reactive than aldehydes toward  nucleophilic
     addition.

C.   Aldehydes and Ketones With Additional Functional Groups—This subcategory
     is comprised of aldehydes and ketones which contain  functional groups other
     than the carbonyl function and simple alkyl or aryl  groups.  Halogenated
     species are included in this subcategory.
                                     B-10

-------
                 CATEGORY 8:  CARBOXYLIC ACIDS AND DERIVATIVES

     Carboxylic acids are highly polar.  They are characterized by the presence

of the carboxyl group, -C-OH ,  attached to either an alkyl or an aryl group.
                         o
The presence of the carbonyl function permits these compounds to function as

acids.   Their chief chemical reaction is loss of H  and replacement by another

group.   They can also react with bases to form salts.   Other important reactions

include formation of esters and amides.
     This category is divided into four subcategories:

A.   Carboxylic Acids--Included are simple aromatic or aliphatic carboxylic
     acids.   Diacids are also included.

B.   Carboxylic Acids with Additional Functional Groups—Included are (1)
     aliphatic acids with additional functional groups on carbon atoms other
     than the carbonyl carbon; (2) aromatic acids with additional functional
     groups substituted on the aromatic ring.

C.   Amides—Compounds in which the OH of the carboxyl ic acid is replaced
     by -NH2 are included in this subcategory.  Lactams are a special kind of
     amide in which a hydrogen attached to the nitrogen is substituted by an
     alkyl function which forms a cycle with the carbonyl carbon.

D-   Esters—Esters are formed wljien carboxyl ic acids condense with primary or
     secondary alcohols.   (The H  is replaced by the alkyl or aryl portion of
     the alcohol, and water is formed).   Certain esters are grouped as subspe-
     cies since an almost unlimited number of combinations are possible.


                             CATEGORY 9:  NITRILES

     Nitriles are organic compounds which contain the cyano group -CSN.   They
are prepared by heating alkyl halide or diazonium salts with inorganic cyanide.

     Nitriles may hydrolyse in water to yield the corresponding Carboxylic

acid, or they may decompose with heat to give toxic cyanide vapors.   The lower

molecular weight nitriles are as toxic as the inorganic cyanides.

     Category 9 is divided into two subcategories:

A.   Aliphatic Nitrile--Aliphatic nitriles are compounds with the general
     formula RCN, where R is an aliphatic group.

B.   Aromatic Nitriles—Aromatic nitriles are compounds with the general
     formula ArCn, where Ar is an aryl group.
                                     B-ll

-------
                             CATEGORY 10:   AMINES
     Amines are compounds of the general  formula RNH2, RgNH, or R3N, where R
is any alkyl or aryl group.   They are prepared by the reduction of nitro-
compounds, the reaction of halides with ammonium or other amines, the catalytic
reduction of the carbonyl function in the presence of ammonium, or by the
reduction of nitriles.   They are converted by acid to their salts, and the
halides, nitrates, and sulfates are water soluble.
     Aliphatic amines are about as basic as ammonia; aromatic amines are
considerably less basic.   The latter are generally very toxic and may be
absorbed through the skin.  The presence of the amine function on an aromatic
ring activates the ring toward substitution.  They are easily oxidized to the
corresponding phenols.
     This category is divided into four subcategories:
A.   Primary Aliphatic Amines and Diamines—Compounds with a single aliphatic
     group attached to nitrogen are called primary amines.  Other functional
     groups such as hydroxyl groups may also be present.
B.   Secondary Aliphatic Amines—Compounds in which two alkyl groups are
     attached to nitrogen are secondary amines.  The alkyl groups may be similar
     or they may be different.  Cyclic nonaromatic rings containing nitrogen
     are included in this subcategory.
C.   Aromatic Amines and Piamines—Compounds *n which an aromatic ring is
     attached to nitrogen are called aromatic amines.  Other functional groups
     such as halides may also be attached to the ring.
D.   Tertiary Amines (Alkyl. Aryl)---Compounds in which three groups, alkyl or
     aryl, are attached to nitrogen are called tertiary amines.
                                     B-12

-------
             CATEGORY 11:  AZO COMPOUNDS AND HYDRAZINE DERIVATIVES

     Category 11 is comprised of compounds containing nitrogen-nitrogen

bonds.  It is divided into two subcategories:

A.   Azo compounds—Azo compounds contain the group-N=N- with a carbon to
     nitrogen linkage on both sides.  The groups attached to the nitrogens may
     be aliphatic or aromatic.  Aromatic azo compounds are highly colored
     compounds, often called azo dyes.  They were first prepared from coal tar
     and are sometimes referred to as coal tar dyes.

B.   Hydrazine derivatives--Hydrazine, the parent compound of these structures,
     is an inorganic compound.  The organic derivatives, however, are similar
     to azo compounds.  They contain the group -N-N- and have the general
     formula R-N-N-R' where R'is an aliphatic or aryl group.
                          CATEGORY 12:  NITROSAMINES

     The generalized structure for nitrosamines is   ^N=N=O.  They are formed
                                                    R
when an aliphatic or an aromatic secondary amine reacts with nitrous acid.

Nitrosamines are generally neutral compounds, insoluble in water and in dilute

aqueous mineral acids.  Many nitrosamines are carcinogenic.

     Category 12 is divided into two subcategories:

A.   Aliphatic Nitrosamines--These compounds have the general structure R-N-N=O
     where R is an aliphatic group.

B.   Aromatic Nitrosamines—Aromatic nitrosamines have the same general structure
     as the aliphatic nitrosamine, where R is an aryl group.
                                     B-13

-------
                CATEGORY 13:   THIOLS, SULFIDES, AND DISULFIDES


     Category 13 is comprised of hydrocarbons which contain sulfur atoms.

It is divided into two subcategories:

A.   Thiols—Thiols, formerly called mercaptans, are alcohols in which sulfur
     replaces the oxygen in the hydroxyl function.  They have the general
     formula RSH where R may be either an aliphatic or aryl group.  They
     are formed from alcohols and hydrogen sulfide in the presence of certain
     catalysts.
          The common thiols are gases or liquids of high vapor pressures.
     They have very offensive odors which may cause nausea and headache.  They
     are generally less toxic than hydrogen sulfide and are somewhat more
     acidic than the corresponding alcohols.  They are flammable and emit S02
     upon decomposition.  Odor is the most important characteristic associated
     with thiols.

B.   Sulfides and Disulfides—Sulfides and disulfides are also sulfur contain-
     ing organic compounds.  Sulfides have the general formula RSR' where R
     and R1 may be either aliphatic or aryl groups.
          Disulfides are characterized by sulfur-sulfur bonds with the general
     formula RSSR'.  R and R1 may be either aliphatic or aryl.


                   CATEGORY 14:  SULFONIC ACIDS, SULFOXIDES

     Category 14 is comprised of organic compounds containing  sulfur-oxygen

bonds.

     The category is divided into two subcategories:
Sulfonic acids—These are highly polar compounds that completely ionize
in aqueous solutions.  As a class they are more water soluble than any other
group of organic compounds.
     The structure of the sulfonic acids is best explained by the following
diagram.  Each pair of dots represents a pair of electrons.
                                 : 0 :
                                R:S:0:H
                                  :p:"

     Aliphatic sulfonic acids are of minor importance.  Their preparation from
thiols requires a powerful oxidizing agent and is unlikely.  Aryl sulfonic
acids formed by the sulfonation of a benzene ring are more common.  Sulfonic
acids are strong acids.  They form salts readily and will probably be isolated
as calcium, barium or lead salts.

Sulfoxides—Sulfoxides are oxidized sulfides.  The general structure may be
represented as follows:
                                 '•?•'
                               R  :S'- R

-------
            CATEGORY 15:  BENZENE, SUBSTITUTED BENZENE HYDROCARBONS

     This category is comprised of benzene and compounds with simple alkyl or

aryl substitution at one or more positions on the benzene ring.   Fused poly-

cyclic compounds with two or more aromatic rings are not included in this cate-

gory.  Cyclic structures such as indan and hydronaphathalene are included

since they contain only one aromatic ring.

     Category 15 is divided into two subcategories:

A.   Benzene and Monosubstituted Benzene Hydrocarbons—This subcategory con-
     tains the single aromatic ring unit as well as aromatic rings substituted
     at a single position.   The general formula for this subcategory is ArR
     where R may be either an aliphatic or an aryl group.

B.   Pi substituted and Polysubstituted Benzene Hydrocarbons—This subcategory
     includes compounds with an alkyl or aryl substitution at two or more
     positions on the benzene ring.   The general formula for this subcategory
     is ArR  where n is any number from 2 through 6 or R may be  any aliphatic

     or aryl group.
                CATEGORY 16:  HALOGENATED AROMATIC HYDROCARBONS

     This category is comprised of simple aromatic rings with halogen or alkyl

halide substituents.

     The category is divided into two subcategories:

A.   Ring Substituted Aromatics—This subcategory contains compounds in which
     one or more halogens are attached directly on an aromatic ring.  Because
     of the numerous substitution sites on the ring,  several isomers are
     possible for most of the aryl halides.
          The chemical reactivity of these aromatic compounds is influenced
     substantially by the presence of the halogen on the ring.   The ring is
     deactivated and undergoes further ring substitutions only with diffi-
     culty. '

B.   Aromatics with Halogenated Alkyl Side Chains—Included are aromatic
     compounds having an alkyl side chain in which one or more hydrogens are
     substituted by halogen.  These compounds do not behave chemically in the
     same way as aryl halides.  Since the site of the halogen on the side
     chain is active, the chemical reactions characteristic of these compounds
     are similar to the reactions of the alkyl halides of Category 2.
                                     B-15

-------
                    CATEGORY 17:   AROMATIC NITRO COMPOUNDS
     Aromatic compounds containing a nitro substituent on a benzene ring are
contained in this category.   The presence of the nitro groups on a benzene
ring tends to deactivate the ring toward further substitution.  The positions
ortho and para to the nitro group are deactivated more than meta positions.
     Category 17 is divided into two subcategories:
A.   Simple Aromatic Nitro Compounds—This subcategory consists of nitro
     groups substituted on aromatic ring structures such as benzene or
     toluene.  Nitrobenzenes are catalytically reduced amines.
B.   Aromatic Nitro Compounds with Other Functional Groups—Nitro compounds
     containing halo, methoxy or similar functional groups are included in
     this subcategory.  Nitrophenols are listed in Category 20.

                             CATEGORY 18:  PHENOLS
     Phenol and phenolic compounds are characterized by a hydroxyl group
attached directly to an aromatic ring.  The general formula is ArOH, where Ar
is an aromatic ring.  The ring may contain additional alkyl or aryl substi-
tutions.
     The category is divided into three subcategories:
A.   Monphydrics--These compounds contain only one hydroxyl group on a ring or
rjyj
ti
     substituted ring.
B.   Dihydrics, Polyhydrics—These are compounds in which two or more hydroxyl
     functions are attached to a ring.
C.   Fused Ring Hydroxy Compounds—These polycyclic compounds contain a hydroxyl
     group.
     Halophenols and nitrophenols are listed in Categories 19 and 20, respec-
tively.
                                     B-16

                 CATEGORY 19:  HALOGENATED PHENOLIC COMPOUNDS

     Phenolic compounds with halogen substituents are included in this cate-

gory.  This category is divided into two subcategories:

A.   Halophenols—Halophenols are phenolic cojjpounds with one or more halogen
     substituents attached directly to the hydfroxy-benzene ring.  The presence
     of the halido significantly increases the acidity of the phenol.  For
     this reason the halophenols are distinguished as a group.

B.   Halogenated Cresols--Ha1ogenated cresols are comprised of those compounds
     formed by the direct attachment of halo substituents to a cresolic
     structure.


                          CATEGORY 20:  NITROPHENOLS

     This category consists of compounds containing both the hydroxyl and the

nitro functional groups substituted on an aromatic ring.  The category is

divided into two subcategories:

A.   Nitrophenols—Nitrophenols are phenolic compounds with one or more sub-
     stituent nitro groups.   Nitrophenols are more acidic than other+phenols
     since the presence of the nitro group on the ring enables the H  from the
     hydroxyl function to be released more easily.

     Because phenols offer a number of active substitution sites, a variety
     of isomers may be formed when the ring is nitrated.

B.   Nitrocresols—Nitrocresols contain one or more nitro groups substituted
     on a cresolic structure.

                  CATEGORY 21:   FUSED POLYCYCLIC HYDROCARBONS

     Compounds included in this category are those with two or more fused
benzene rings.  Compounds containing the cyclopenta ring (called non-alternant
compounds) do not permit the same degree of resonance as compounds which have
only fused benzene rings.  The behavior of the non-alternant compounds is
different as a result of the limited resonance.   The non-alternants are not
included with the naphthalene family of fused aromatics but are treated
separately as Category 22.
     Unlike many chemical classes of compounds,  toxicity data from one poly-
nuclear aromatic cannot be extrapolated to predict toxicity of structurally
similar compounds.  Within this category, minor changes in structure may
drastically effect oncogenic properties of these compounds.  Each compound
must be examined individually for indication of its carcinogenic potential.
     The division into subcategories is based on the number of rings in the
compound.  Alkyl derivatives of the polycyclics are also included.  Subcate-
gories are:
A.   Two and Three Ring Fused Polycyclic Hydrocarbons
B.   Four Ring Fused Polycyclic Hydrocarbons
C.   Five Ring Fused Polycyclic Hydrocarbons
D.   Compounds with More Than Five Fused Rings
                                     B-18

-------
           CATEGORY 22:  FUSED NON-ALTERNANT POLYCYCLIC HYDROCARBONS

     Compounds included in this category are characterized by the presence of
a cyclopenta ring attached to one or more benzene rings.  These compounds are
distinct from compounds comprised of fused benzene rings.
     The term non-alternant applies to fully conjugated hydrocarbons that
contain rings with an uneven number of carbon atoms.   In general, resonant
structures cannot be drawn for compounds containing the cyclopenta ring (hence
the name non-alternant) as can be done for the fully aromatic fused ring com-
pounds.
     Unlike many chemical classes of compounds, toxicity data from one poly-
cyclic hydrocarbon cannot be extrapolated to predict toxicity of structurally
similar compounds.  Within this category, minor changes in structure may
drastically effect oncogenic properties of these compounds.   Each compound
must be examined individually for indication of its carcinogenic potential.
     Category 22 is divided into, four subcategories:.
A.   Two- and Three-Ring Fused Non-alternant Polycyclic Hydrocarbons
B.   Four Ring Fused Non-alternant Polycyclic Hydrocarbons
C.   Five Ring Fused Non-alternant Polycyclic Hydrocarbons
D.   Compounds with More Than Five Fused Rings
                                     B-19

                 CATEGORY 23:   HETEROCYCLIC NITROGEN COMPOUNDS


     A heterocyclic compound is one that contains a ring made up of more than

one kind of atom.   A nitrogen heterocycle contains nitrogen as a member of an

aromatic carbon ring.

     Unlike many chemical classes of compounds, toxicity data from one fused

heterocycle cannot be extrapolated to predict toxicity of structurally similar

compounds.   For this category, minor changes in structure may drastically

effect oncogenic properties of these compounds.  Each compound must be examined

individually for indication of its carcogenic potential.

     This category is divided into four subcategories as follows:

A.   Pyridine and Substituted Pyridines—Pyridines are distinguished by the
     presence of nitrogen as a hetero atom within a six-membered aromatic
     ring.

B.   Fused Six-Membered Ring Heterocycles—These compounds contain two or more
     fused six-membered rings with one ring containing nitrogen as a hetero
     atom.

C.   Pyrrole and Fused Ring Derivatives of Pyrrole--Compounds in this sub-
     category are characterized by the five-sided ring containing a nitrogen
     hetero atom.

D.   Nitrogen Heterocycles Containing Additional Hetero Atoms—Included in
     this subcategory are those compounds containing nitrogen and other atoms,
     such as sulfur, as hetero atoms in aromatic rings.

-------
                  CATEGORY 24:  HETEROCYCLIC OXYGEN COMPOUNDS
     Heterocyclic oxygen compounds are characterized by an oxygen atom as a
member of an aromatic ring.  The oxygen heterocycles are all derived from the
five-membered heterocycle ring called furan or from xanthene which contains a
six-membered heterocycle ring.
     Category 24 is divided into two subcategories dependent upon the number of
rings in each compound.   The subcategories are:
A.    One and Two Ring Heterocyclic Oxygen Compounds
B.    Three or More Ring Heterocyclic Oxygen Compounds
                 CATEGORY 25:  HETEROCYCLIC SULFUR COMPOUNDS
     Heterocyclic sulfur compounds are characterized by a sulfur atom as a
member of an aromatic ring.  The sulfur heterocycles are all derived from the
five-membered ring called thiophene.
     Category 25 is divided into two subcategories depending on the number of
rings involved in the formation of the compound.  The subcategories are:
A.   One Ring Heterocyclic Sulfur Compounds
B.   Two or More Ring Heterocyclic Sulfur Compounds
                   CATEGORY 26:  ORGANOPHOSPHOROUS COMPOUNDS
     Organophosphorous compounds are carbon compounds which contain one or
more atoms of phosphorous.  Two subcategories are specified:
A.   Aliphatic Phosphates
B.   Aromatic Phosphates
                                     B-21

  TABULATED MINIMUM ACUTE TOXICITY EFFLUENT (MATE) VALUES FOR ORGANIC CHEMICALS


     Minimum Acute Toxicity Effluent (MATE) values describe concentrations of
contaminants in source emissions to air, water, or land that will not evoke
significant or irreversible harmful responses in human populations or eco-
systems that might be exposed, provided the exposures are of limited duration.
MATE values for air, water, and solid waste are tabulated in this appendix for
each organic compound currently addressed by MEGs.  The compounds and their
MATE values are listed by category.  MEG identification numbers are provided
for cross reference with the complete MEG charts and background information
summaries in Appendix A (Volumes III and IV).

     The tabulated MATE values correspond to the MATE values given under
Emission Level Goals on the MEG charts in Appendix A.  The user should consult
the charts and summaries in Appendix A for the bases of MATE values for each
chemical.  The absence of MATE values indicates that necessary data are not
available.

     Compounds in italics are subspecies; information on these compounds is
included with the summary for the parent species (the name of the parent
species precedes the italicized compound).   Values for MATEs are expressed in
scientific notation to facilitate comparison and to simplify presentation; the
number following the~"E" is understood to be the exponent of 10.  For example,
4.2E3 means 4.2 x 10 , or 4,200.

     A listing of the most stringent MATE values for each subcategory follows
the complete MATE value table.

     Models used to derive the MATEs are summarized in Tables 2 and 3 in
Section 2.5 of this volume.  In applying the values tabulated in this appen-
dix, *=the user should be aware that the MATEs are dependent upon data such as
TLVs , NIOSH recommendations, lethal and sublethal concentrations or doses and
existing Federal guidelines for environmental protection.  There are uncer-
tainties associated with these basic data,  and in addition, arbitrary safety
factors are incorporated in some of the equations to generate the MATEs.  A
worst case approach is applied consistently, however, so that the reported
values are expected to err on the conservative side.

     This listing supersedes the MATE values for Categories 1-25 tabulated in
Appendix C of the 1977 MEGs report, Volume I.*

                     HAZARD INDICATORS FOR ORGANIC CHEMICALS


     This appendix lists hazard potential values for organic MEG compounds.
The values have been calculated on the bases of air EPC's and reflect severity
of possible human health effects.   High values indicate very hazardous chemicals.
Hazard indicators (X, XX, or XXX) are assigned to the compounds of high con-
cern based on the calculated potential hazard values.   The XXX indicator
denotes substances of greatest concern.  The hazard indicators appear in the
upper right corner of the MEG charts provided in Appendix A (MEG Volumes III
and IV).

     Compounds and their hazard potential values are listed by MEG category.
Only main names, i.e., the preferred name or parent name appearing on a MEG
chart in Appendix A, are included.  Subspecies are not listed individually.
Missing hazard potential values in the listing indicate that data are unavail-
able to calculate an EPC for air based on health effects.

     A list of the 68 organic substances receiving hazard indicators is given
following the index of hazard potential values.

     Hazard potential values presented in this appendix supplant the values
for organics in Appendix D of the 1977 MEGs report, Volume I.*

                                     INDEX


     Throughout the MEGs reports, data are arranged by category, and infor-
mation for a specific compound is located quickly using the assigned MEG
identification numbers.   An alphabetical listing of organic compounds and
their MEGs identification numbers are provided in this appendix.  The listing
includes all preferred names and synonyms appearing on the background infor-
mation summaries for organic compounds.   A total of 586 chemicals are
indexed.

     A molecular formula index for the organic MEG compounds follows the
alphabetical listing.

                                  APPENDIX G

                    GRAPHICAL SUMMARIES OF MEGs FOR ORGANICS
     This appendix presents graphical summaries of the EPCs and MATEs for all
organic chemicals addressed in MEGs Volumes III and IV.  The graphs show for
each subcategory the ranges in the MEG values based on health and based on
ecology.   Relative toxicities of the various categories and subcategories are
readily apparent from the graphs.

     Point values for specific chemicals are indicated.  Individual chemical
ID numbers are also shown.  Both health and ecology based values are given.

     Goals that are based on potential carcinogenicity are flagged so that
subcategories with a number of chemicals classified as suspected carcinogens
are evident.

     Separate graphs are given for air and water.

16. ABSTRACT
              report supplements Volume I (E PA- 600/7-77-136a) of the two-volume
1977 EPA report that introduced a methodology to establish Multimedia Environmen-
tal Goals (MEGs) for chemical pollutants.  It summarizes the original methodology
and introduces minor improvements. Improvements include the assignment of a
unique identification number to each MEG compound and modification of the original
model used to derive MEG values for land or solid waste.  Its appendices include:
revised category descriptions, an updated master list of organic compounds, a
candidate list of  compounds to be considered for future MEGs , tabulated discharge
MEG values, and hazard potential values.  It also includes graphical summaries of
MEGs for 586 organic chemicals. The Supplement is to be used in coordination with
MEG Volumes  III and IV (EPA-600/7-79-176a and -176b) which contain background
information summaries and MEG charts for organic compounds in the new MEGs
master list.
