Polycyclic aromatic hydrocarbons (PAHs) are a large class of chemicals and common environmental pollutants. Understanding which PAHs and soil test levels may impact human health is an important aspect of gardening and micro-farming, particularly in urban environments that are at increased risk of soil contamination. Land use histories, such as sites associated with vehicle and industrial emissions, burning, and dumping, can elevate concentrations of PAHs in soils. This fact sheet provides instructions on assessing your site for PAHs that may present health risks to humans, testing the soil, and first steps for interpretation and management.
