Where It Comes From
Made during petroleum refining and used in chemical manufacturing; present in fuels and released during storage, transport, and spills. [1]
How You Are Exposed
Breathing vapors at gas stations, airports, refineries, or garages; using fuel/solvent products indoors; contact with contaminated soil or groundwater near spills. [1][3]
Why It Matters
Short-term exposure can cause irritation, headaches, and dizziness; very high levels may depress the central nervous system. Repeated exposure (animal and hydrocarbon data) suggests possible liver and kidney effects. There is no established cancer classification for this chemical. [1][2]
Who Is at Risk
Fuel and petrochemical workers, mechanics, people near refineries/airports/spill sites; pregnant people and children may be more sensitive. [1][3]
How to Lower Your Exposure
Limit time around fuel vapors; don’t top off the tank; store fuels tightly closed and ventilate when using solvents; fix fuel leaks; follow workplace controls/PPE; consider well-water testing if near spills. [1][3]
