Symptoms Related to the Physical, Chemical, and Toxicological Characteristics
Symptoms: Inhalation of high vapor concentrations may cause symptoms like headache, dizziness,
fatigue, nausea, and vomiting.
Delayed and Immediate Effects and also Chronic Effects from Short and Long Term Exposure
Sensitization: May cause sensitization to susceptible persons.
Mutagenic Effects: No information available.
Carcinogenicity: The table below indicates whether each agency has listed any ingredient as a carcinogen.
The IARC, NTP, and OSHA do not list asphalt as a carcinogen. In general, the oxidation of
polycyclic aromatic hydrocarbons destroys their carcinogenic potential. Petroleum asphalt,
shale oil asphalts, and coal tars show distinct variation in their relative carcinogenicity for
experimental animals.
