How harmful is PAHs (polycyclic aromatic hydrocarbons — grilled meats, air)?

PAHs (polycyclic aromatic hydrocarbons — grilled meats, air) is rated MODERATE exposure concern (5.3/10) on the Read Off Label scale, derived from strong evidence of moderate harm magnitude and low-moderate dietary exposure prevalence.

Bottom line

Read Off Label rates PAHs (polycyclic aromatic hydrocarbons — grilled meats, air) a MODERATE exposure concern (5.3/10) based on strong evidence of moderate harm magnitude and low-moderate dietary exposure prevalence.

Marination reduces PAH formation substantially (vinegar/citrus/rosemary components).

This entry describes an exposure rather than an added intervention.

What the evidence says

Marination reduces PAH formation substantially (vinegar/citrus/rosemary components). Cooking method matters more than meat quality. Also formed when fat drips onto hot surfaces — vertical grilling or foil-wrapping reduces exposure. Airborne PAH from nearby combustion sources is a separate exposure route.

Mechanism

Formed during incomplete combustion — grilled/charred meat, diesel exhaust, tobacco smoke, industrial combustion; benzo[a]pyrene is prototype IARC Group 1 carcinogen

Reported exposure / mitigation context

Charring and direct flame increase PAH formation; marination and sous vide and indirect cooking reduce formation
