Where It Comes From
Vehicle exhaust, industrial emissions, residential wood smoke, tobacco smoke, coal tar/creosote, asphalt, and grilled/charred foods [1][2].
How You Are Exposed
Breathing polluted air or smoke, skin contact with soot/asphalt/creosote or contaminated soil, and eating charred or smoked foods [1][2].
Why It Matters
PAHs can irritate skin and lungs; some PAHs and PAH mixtures cause cancer. Data for methylanthracene is limited, so it’s managed like other PAHs as a precaution [1][3][4].
Who Is at Risk
Workers with asphalt, roofing, paving, coke ovens or aluminum production; firefighters; smokers and families; people near heavy traffic; pregnant people and children [1][2][3].
How to Lower Your Exposure
Keep indoor air smoke-free, avoid idling and wood smoke, cook at lower temps and avoid charring, use ventilation when frying/grilling, wear gloves/coveralls when handling creosote/asphalt, and wash off soot promptly [1][2].
