IARC classifies wooddust as a carcinogen to humans (Group1). This classification is based primarily onIARC’s evaluation of increased risk in the occurrence of adenocarcinomas of the nasalcavities and paranasal sinuses associated with exposure to wood dust. IARC did not findsufficient evidence to associate cancers of the oropharynx, hypopharynx.lung, lymphaticand hematopoietic systems, stomach colon or rectum with exposure to wood dust. TheNational Toxicology Program lists wood dust as a known human carcinogen in the NTP’stenth Report on Carcinogens.
