c Based on classification in Reference 29; +- uncertain or weakly carcinogenic; + carcinogenic; ++, +++, ++++ strongly carcinogenic.
d Average of results from Tables 20 and 22 of Reference 21 excluding SASS train results for green pine in stove.
e These compounds were not specifically identified except as a group.
f I Included in the benz(a)anthracene number;
g See footnote c, Table I.
h Total will be upper limit because of the inclusion of some noncarcinogenic isomers included in the general classes measured. The benzopyrene class value was not used, only the benzo(a)pyrene value.
