Cumene (1-methylethylbenzene): Health effects
Description
Short-term exposure to high levels of cumene results first in headache, irritation of the eyes, nose and throat, euphoria, followed by dizziness, sleepiness, and unconsciousness. Cumene is a central nervous system depressant and may cause narcotic effects. Long-term exposures at low levels have caused effects to the liver and kidneys.
Entering the body
Cumene will enter the body if we breathe in contaminated air, or breathe in tobacco smoke. Human exposure occurs mainly by breathing air containing cumene, from the evaporation of petroleum products. Cumene can pass through the skin.
Exposure
Workers in the industries that use or produce cumene are at risk of exposure. Consumers can be exposed to cumene by exposure to air from production and processing facilities using cumene, automotive exhaust, and tobacco smoke. Consumers may also be exposed to cumene when using consumer products containing cumene (thinners for paint lacquers and enamels, foam insulation, etc) especially if there is not good ventilation.
Health guidelines
Worksafe Australia:
For cumene, it is allowable for workers to be exposed to concentrations of 50 parts per million over an eight hour workshift.
