Where It Comes From
Vehicle exhaust, residential wood/coal smoke, wildfires, coal tar/creosote/asphalt, and other high‑temperature processes; it often sticks to airborne particles and dust [1].
How You Are Exposed
Breathing smoky or traffic‑polluted air, eating heavily charred/grilled or smoked foods, contact with contaminated soil/dust or sediments, and certain jobs (paving, roofing, coke ovens, aluminum production) [1].
Why It Matters
High exposures can irritate eyes/skin and affected organs in animals; PAH mixtures are linked to cancer, though fluoranthene itself is “not classifiable” for cancer by IARC; EPA provides a non‑cancer oral reference dose [1][2][3].
Who Is at Risk
People living near busy roads or industrial burners, smokers, children (hand‑to‑mouth contact with dust/soil), and workers handling coal tar, asphalt, or creosote or working with combustion processes [1].
How to Lower Your Exposure
Avoid smoke and idling exhaust; use kitchen exhaust and limit charring when cooking; follow local fish/shellfish advisories; remove shoes and wet‑wipe dust; wash hands; use ventilation and PPE at work [1][2].
