IARC MONOGRAPHS ON THE EVALUATION OF CARCINOGENIC ...

AFLATOXINS
These substances were considered by previous working groups, in December 1971
(IARC, 1972), October 1975 (IARC, 1976), March 1987 (IARC, 1987) and June 1992
(IARC, 1993). Since that time, new data have become available, and these have been
incorporated into this updated monograph.
