Learn about PAHs: formation, health risks, and food sources. Find out how to reduce exposure to these environmental contaminants.
Polycyclic aromatic hydrocarbons (PAHs) are a group of organic environmental contaminants formed during the incomplete combustion of organic matter such as fossil fuels, wood, or tobacco.
Polycyclic aromatic hydrocarbons can accumulate in air, soil, water, and food, particularly in grilled meat or smoked products.
Several PAHs are of major health concern because they are classified as carcinogenic. A key example is benzo[a]pyrene, often used as an indicator compound in risk assessment. In addition to cancer risks, PAHs can cause genotoxic effects and impair the immune system.
To protect consumers, the European Union has established strict limits for selected PAHs in food. Continuous environmental and food monitoring is mandatory, and simple measures such as avoiding heavily charred grilled food or excessive smoke exposure can reduce personal intake.
