Thisclassification was made based on inadequate evidence for the carcinogenicity ofundiluted air-refined bitumens in experimental animals and inadequateevidence that bitumens alone are carcinogenic to humans. However, asphaltdoes contain a small amount of polycyclic aromatic hydrocarbons which havebeen shown to cause cancer and respiratory damage in on a 2000 review of health effects literature, NIOSH concluded thatroofing asphalt fumes are a potential occupational black :Skin:Skin - Rabbit LD50: >3 gm/kg - [Details of toxic effects not reported otherthan lethal dose value.]
