This project was supported by PHS Grant No. 1 U01 CA33193-03 awarded by the US National Cancer Institute, Department of Health and Human Services.

Inclusion of a chemical in the rnonographs does not imply that it is a carcinogen, only that the published data have been examined. Equally, the fact that a chemical has notyet been evaluated in a monograph does not mean that it is not carcinogenic. Anyone who is aware of published data that may alter the evaluation of the carcinogenic risk of a chemical to humans is encouraged to make this information available to the Unit of Carcinogen Identification and Evaluation, Division of Environmental Carcinogenesis, Inter- national Agency for Research on Cancer, 150 cours Albert Thomas, 69372 Lyon Cedex 08, France, in order that the chemical may be considered for re-evaluation by a future Working Group. Although every effort is made to prepare the monographs as accurately as possible, mis- takes may occur. Readers are requested to communicate any errors to the Unit of Carcino- gen Identification and Evaluation, so that corrections can be reported in future volumes. -5- IARC WORKING GROUP ON THE EVALUATION OF THE CARCINOGENIC RISK OF CHEMICALS TO HUMANS: TOBACCO HABITS OTHER THAN SMOKING; BETEL-QUID AND ARECA-NUT CHEWING; AND SOME RELATED NITROSAMINES Lyon, 23-30 October 1984 Members1 S.V.
