   Building on an earlier  EPA report entitled  "On Ordering of  the NIOSH Suspected  '
   Carcinogens List Based  Only on Data Contained in the List"  (EPA 560/1-76-001),
   the present document represents the second  OTS effort to arrange the substances
   presented in the NIOSH  Suspected Carcinogens Subfile in a meaningful and useful
   way for  EPA purposes.   Employing readily available information on the uses and
   commercial significance of the chemicals listed in the NIOSH Subfile, OTS has'
   further  refined the initial ordering into the four tables contained in this  report.

     The National Institute of Occupational Safety and Health  (NIOSH) annually


publishes the Registry of Toxic Effects of Chemical Substances  (RTECS), formerly  '•"


called the Toxic Substances List.  In 1975, NIOSH published a subfile of the


RTECS, Suspected Carcinogens, A Subfile of the NIOSH Toxic Substances List, which.


lists chemicals reported in the literature as having caused benign or malignant
                                                                         .,'..- .;.••₯.- — •

tumors in at least one species.  The obvious concern over this  list of chemicals


and the fact that some might fall within the Environmental Protection Agency's


(EPA's) regulatory jurisdiction by virtue of their use patterns led the EPA        '.'


Office of Toxic Substances (OTS) to undertake an effort to identify those sub-


stances in the Subfile deserving OTS attention.  Initially, the NIOSH Subfile was


reordered according to cited carcinogenicity data.  That ordering  (summarized in  -


the Appendix) suggests the degree of concern that might be warranted regarding


the carcinogenic potential of the listed chemicals.


     Employing readily available information on uses and commercial significance,
                                                                        J -   • . ' '    .'
OTS has further refined the initial ordering into the four tables contained in

                                                                       '.'.' " '.'. ' .'
this report.  Table 1 lists chemicals that might need delineation of their envi-


ronmental hazard potential—particularly their carcinogenic threat.  The chem-


icals contained in Tables 2 and 3 are considered less significant at this time


because they either fall more appropriately under another agency's regulatory


authority (Table 2) or because (Table 3) insufficient information was developed '••

                                                                       '' ' •   '••'   > '-
to warrant the inclusion of the entries in another table.  It should be. recog-


nized, however, that some chemicals in Tables 2 and 3 may become environmentally


important in the future as their uses change.  Table 4 is a composite of the   . '^

investigated by other than environmentally significant routes of administration




which, nonetheless, produced tumors at sites remote from the point of introduc-




tion.  Some of the entries in Table 4 might require additional definition as was




suggested for Table 1 chemicals.



     The tables in this report share limitations with the NIOSH Subfile data.  In




particular, a substance's inclusion in the NIOSH Subfile is based on the con-




clusions of the author(s) of the study cited that the investigated substance




produced a neoplastic or carcinogenic response.  In many cases the only data




evaluation in evidence is that provided by the scientific community prior to




publication in private literature.  Neither NIOSH nor OTS has attempted to



resolve questionable published data or to evaluate an author's interpretation.




It is not appropriate to conclude that all substances listed in this report are




carcinogenic or of regulatory interest to EPA.

                                  I.  APPROACH
     After the initial ordering of an updated version  of  the  1975  NIOSH  Sus-

pected Carcinogens Subfile in March 1976, EPA made refinements to provide a
                                  .• - -
better definition of the environmental exposure for each substance  on  the list.

Efforts were made to ascertain the commercial significance of  the chemicals.

This was done primarily by using information readily available in the  secondary

sources referenced herein; however, examination of the primary literature was

also necessary in a few cases.  The basic factors examined were production levels

(when available) and commercial applications.  Chemicals that  have  received in-

depth carcinogenicity evaluations by the International Agency  for Research on

Cancer (IARC) were also identified.

     An understanding of the/approach used to develop this list is  facilitated

by referring to Figure 1, a flow diagram presenting a schematic of  the entire
                                                •' *•'•''• .                       ' '
process.  Starting from point A, a e.pmbination of machine  and  manual techniques
                                   *-.*.*  ' •"

was used to reduce and define the list of 1,693 compounds  contained in the ini-

tial EPA-ordered NIOSH Subfile of Suspected Carcinogens.   First, the availability

of a Chemical Abstracts Services (CAS) registry number was determined  for each

compound.  This determination was important because only those chemicals  pos-

sessing a CAS number would be eligible for the subsequent  automated search;  of

the 1,693 compounds in the NIOSH Subfile, only 928 had CAS numbers.  The  machine

manipulation (B) consisted of a comparison between the CAS-numbered NIOSH Subfile

entries.and those chemicals contained on the Stanford Research Institute's  (SRI)

file of 26,755 commercially significant (COMSIG) chemicals.  The intersection of

the two lists produced matches of 632 compounds.
 NIOSH made this updated version of the published subfile available to'OTS on
 computer tape.

                                    1

-------
     For the 765 substances having no CAS number, a manual search of  the TSCA

Candidate List of Chemical Substances (April 1977) and other information sources

was conducted to determine the commercially significant chemicals (step C).  This
                                                              ' "          "'*'•. •'•'•'•',
search soon indicated that the overwhelming majority of these  compounds have.

little, if any, commercial significance.  Generally, they are  laboratory research

materials (e.g., experimental carcinogens), analytical reagents, and  members of

certain structural classes known  to have a proclivity to induce carcinogenesis.. .

Some substances in this latter group appear to have been synthesized  at the

laboratory level to test a wider  variety of substances in a given structural

class.  Conceivably, certain compounds  in this category could  have some environ-

mental significance; examples are polynuclear aromatics and N-nitroso compounds.

Only 5 of the 765 compounds without CAS numbers were found >to  have some com-

mercial significance; these were  added  to the list obtained from the  COMSIG

intersection to yield a total of  637 chemicals.

     Step D involved examination  of the route of  exposure  (e.g., inhalation vs.

oral vs. injection, etc.) recorded for  each chemical as represented by the  third

digit of the OTS 4-digit ranking  code.  In general, an oncogenic response  to

level 1 (oral) or level 2 (inhalation,  dermal, or ocular) exposure was considered

more environmentally significant  than responses following level 0 (injection,

implant, etc.) exposure.  Accordingly,  level 1 and level 2 chemicals  were  com-
               "•                                            ~            •'"''' i •••
bined and considered separately from level 0 compounds.  All of the chemicals

from levels 1 and 2 (total of 383) were designated as "hits" in the present work

and would ultimately appear in one of the tables.  Level 0 compounds  (total of

254), on the other hand, were subjected to an additional refining step involving

a determination of level 0 compounds which reported the development of tumors at

sites remote from the point of administration.  Evidence of this nature was con-

sidered more indicative of a chemical's possible  environmental significance than

-------
reports that the chemical produced local tumors only.  While  flaws were  evident


in this approach, it was felt that such a distinction was better  than  inclusion


of either all or none of the level 0 chemicals.  Accordingly,  the primary literar


ture was examined (step E) and the studies  (i.e., compounds)  were separated  into


two groups:  those reporting local tumors only (151 entries)  and  those having


evidence of remote tumor development (103 entries).  The "local tumors only"


chemicals were given no further consideration, while the "evidence of  remote ,


tumors" group would ultimately appear in various parts of Table 4.


     All "hit" chemicals (basically level 1 and level 2 compounds plus the


"remote tumors" subset of the level 0 chemicals) were then subjected to  essen-


tially the same examination process.  Nonprime letters (e.g.,  F)  indicate level 1


and level 2 chemicals, while letters prime  (e.g. G') refer to  the subset of  level


0 chemicals.


     The first common step (F and F') was an intensive examination of  (predomi-


nantly) secondary sources of production and use information.   A listing  of the


publications consulted can be found in the "References" section.  Only very


limited.information was available for a number of the "hit" chemicals; these were


assigned to Table 3 (G; 147 entries) or Table 4C (G?; 12 entries) and  were listed

                                                2
according to their OTS 4-digit rank designation.   Compounds with identical  OTS


rank numbers were listed alphanumerically by NIOSH sort key within each  group.


While many of the substances in these two tables appear to be  of  limited com-


mercial significance (interpreting the paucity of production and  use information


as somewhat indicative of minimal industrial significance), caution is advised
2                            '                                        .->..-
 OTS rank number — a higher number indicates greater evidence of carcinogenic
 potential (see Appendix).

-------
because inclusion in these tables does not reflect a definitive judgment.




     The remaining chemicals were grouped on the basis of their reported uses.




Chemicals of primary interest to the Food and Drug Administration or EPA's Office




of Pesticides Programs were separated as follows (refer to Figures 1 and 2, pp. 7




and 8):




 (a) food^cosmetics related chemicals:  Table 2A (H; 4 entries) and Table 4B-1




     (Hf; 2 entries).




 (b) Pharmaceuticals:  Table 2B  (I; 40 entries) and Table 4B-2  (I1; 31 entries).




 (c) pesticides in Table IB (J; 36 entries) and Table 4A-2 (Jf; 14 entries).




As before, all chemicals were ordered on the basis of their OTS rank code with .?;




the NIOSH sort key used as a second-level sorting parameter.




     The remaining chemicals (a total of 200) represent a core group of sub-




stances from the NIOSH Subfile having the greatest potential interest to the EPA:




Office of Toxic Substances.  Most are Industrial chemicals produced in amounts




ranging from less than 1,000 pounds to several billion pounds per year.  Because




of the wide range in reported production volumes for these chemicals, a dual-




level sorting hierarchy was employed to order the entries.  Production level was




considered first (highest to lowest), followed by the OTS 4-digit rank number.




(As before, entries having identical rankings were ultimately ordered alphanumer-.




ically by the NIOSH sort key.)




     Accordingly, the order in which chemicals are listed in Table 1A  (K; 156




entries) and Table 4A-1  (K'; 44 entries) indicates the relative significance of




these chemicals with regard to their potential for environmental exposure (and




thus their hazard potential).  Of the 156 compounds in Table 1A, at least 60 are




clearly of commercial significance.  Another 51 chemicals are reportedly produced




in quantities greater than 1,000 pounds per year.  The remaining 45 chemicals




                                    4

-------
are currently produced in quantities less than 1,000 pounds per year; however,


the information is sketchy and the chemicals may be of commercial  importance  in


the future, or might have been within the past few years.  Seventy-eight sub-


stances in Table 1A have been evaluated by the IARC in its monographs.   Seven


are indicated to be human positive carcinogens; 4, human suspected; 42, animal


positive; 6, animal suspected; 17, indefinite; and 2, negative.


     Table 4A-1 contains 44 chemicals, 19 of which are of documented commercial


importance.  Sixteen others are produced at levels in excess of 1,000 pounds  per


year, while the 9 remaining chemicals are produced at levels less  than 1,000  . '


pounds or their commercial importance in the recent past or future is uncertain.


Twenty chemicals in Table 4A-1 have been evaluated by the IARC.  Of these, none


are human positive carcinogens; 3, human suspected; 9, animal positive; 3, animal


suspected; and 5, indefinite.


     As a result of this exercise and other factors, preparation of hazard assess-


ment documents has started or is planned for such chemicals as epichlorohydrin,


ethylene glycol, and others.  In addition, for selected unevaluated chemicals


(e.g., no IARC review) that are commercially significant, an in-depth evaluation


of carcinogenicity and other toxicity data will be performed by recognized


experts under extramural contract.  Present plans call for the preparation of


periodic updates to this list as additional suspected carcinogens are identified


by NIOSH.  However, no time frame has currently been established for this work.


     Each of the four tables has seven columns.  Column one identifies each


substance by its unique CAS number.  (Only a few compounds in these tables do


not have CAS numbers.   The CAS numbers used in these tables have been taken

predominantly from the TSCA Candidate List of Chemical Substances  [April  1977];




in cases where the substance was not contained  in the Candidate List, either the




NIOSH Subfile-listed CAS number or  the CHEMNAME data base-reported number was




used.)  Column two gives the OTS rank number assigned to  the chemical in  the



original EPA-ordered version.  Column three lists the alphanumeric sequence

which allows easy location of the main entry.   Column four indicates the  approx-




imate annual production level of a  compound, from I representing 1,000 pounds  to




V representing 1 'billion pounds.  The latest available annual production  figures




are used.  Column five gives a common chemical  or trade name for each substance.




Column six indicates whether an evaluation of carcinogenicity data has been




conducted by the IARC in its monograph reviews; it also contains a symbol repre-




senting the review conclusion at the time of preparation, ranging  from HP for




human positive to AS for animal suspected, and  ID for indefinite.  The last




column lists the uses of the substance,  as found in the various secondary references




consulted.

                               APPENDIX
OTS RANK (FOUR-DIGIT) ASSIGNMENT
       In ordering the initial MIOSH Subfile, a four-digit number (ABCD)
was computed for each compound, utilizing data presented in the toxic
dose lines for that compound.  Only toxic dose lines that had a car-
cinogenic (CAR) or neoplastic (NEO) response noted were used.  For this
effort, CAR and NEO responses were considered equivalent.
       The four-digit numbers were computed using the following criteria:

     o    The first digit, A, represents the species in which a CAR or NEO
          response is reported; assignments are:
               7:   Humans
               6:   Monkeys
               5:   Cat, dog, pig, cattle, or domestic animal
               4:   Rat
               3:   Mouse                            .
               2:   Guinea pig, gerbil, hamster, rabbit, squirrel, or
                       unspecified mammal                              -
               1:   Wild bird, bird, chicken, duck, pigeon, quail, or
                       turkey                                           •
               0:   Frog
          For compounds where CAR or NEO responses are reported in more
          than one species, the highest number is assigned.
     o    The second digit, B, designates the number of different species
          for which CAR or NEO responses are reported, to a maximum of 9.
                                   49

-------
o    The third digit,, C, designates.^he axlrairiistration route for
     which a CAR or NEO response is reported:
          2:   Inhalation, ocular, or skin application   ;;
          1:   Oral administration        v? r"
          0:   All other routes of administration
     Only the highest number is used if CAR or NEO responses are  :;
     reported for more than one route.                  ^^,: ;^--

o    The final digit, D, is the total number of CAR or NEO responses
     reported for this substance, to a maximum of 9;  Because the
     NIOSH Subfile included only one toxic dose line for any route/
                                                        .-- '.:'•'*
     species combination (specifically the.study in which the lowest
     effective dose was reported for that combination); this digit is
     a count of the number of different route/species combinations
     reported to result in, a carcinogenic or neoplastic response, ,
                               50

     The order number for this compound is 5729.  The first digit (5)  is

assigned because a NEO response was  reported in the dog; the second

digit (7) is assigned because a CAR  or NEO response was reported  for

seven different species (rat, mouse, dog,  cat,  rabbit, hamster, and

chicken); the third digit (2) is assigned  because a CAR response  was
                                 51

-------
elicited with a skin application of the substance; and the last digit
(9) is assigned because CAR or NEO responses were reported in 12 dif-
ferent route/species combinations (because the maximum allowable is 9,
the last digit defaults to this).                                   ;'..

RATIONALE
     The following rationale was used to develop the individual digit
assignment for the initial ordering exercise:
   A.   For the first digit, a CAR or NEO response reported in humans or
        primates indicates evidence or suspicion that the compound is a
        human carcinogen.  Cats, dogs, etc., are ranked beneath humans
        on a phylogenic basis.  While the rat and mouse are not phylo-
        genically higher than the small mammals ranked beneath them, it
        is felt that, because these two species have been studied exten-
        sively and their physiological responses to chemical insult are
        far better understood, a CAR or NEO response is probably more
        meaningful than such a response in a less well studied species.
        Between these two species, the rat is given precedence because
        it is both better studied and longer Ifved than the mouse.
   B.   The rationale for the second digit is that a compound shown to
        be carcinogenic or neoplastic in two or more species is more
        :likely to be universally carcinogenic than a compound for which
        the effect has been shown in only one species.
   C.   The third digit indicates the potential for carcinogenic or
        neoplastic response resulting from environmental exposure,  in
        this respect, responses from inhalation or skin application "are
        more indicative of concern for environmental exposure to the

                  -   -             52  -                  ..      \  -  - .:.

-------
        substance than carcinogenic or neoplastic responses occurring
        from injection or implantation.  Oral administration is con-
        sidered intermediate.                                         ,.
   D.   The final digit indicates that the CAR or NEO response has been
        confirmed both in different species (as in the second digit) and
        by different routes of administration within a given species.

     The arrangement of the four digits into the ABCD sequence is based.
on the relative significance of each.  The first digit is considered
most significant because it indicates the human carcinogenic potential
of the compound.  The second digit focuses on the universality of the
response among different species and indicates the likelihood that the
compound has human carcinogenic potential, but to a lesser degree than.
the first digit.  The third digit reflects the next most significant- .
parameter—the type of exposure required to elicit the response.  The
final digit indicates the degree of confidence about the carcinogenic or
neoplastic response associated with the compound.  Due to certain limita-
tions involved in its genesis (for example, many known carcinogens are
studied repeatedly to obtain tumors for further study), the fourth digit
is given the least importance in ordering the compounds.
