PAHs (Polycyclic Aromatic Hydrocarbons)

Quick Definition

Cancer-causing compounds from wildfire smoke that persist on indoor surfaces for 40+ days

PAHs (Polycyclic Aromatic Hydrocarbons) are toxic chemicals created when organic materials burn incompletely during wildfires. These compounds are particularly dangerous because they stick to furniture, toys, and fabrics where your family touches them daily.

What You Need to Know

When wildfire smoke enters your home, PAHs settle on surfaces and can persist for more than 40 days. The EPA has identified 16 priority PAHs that pose serious health risks, including lung damage and increased cancer risk.

Why It Matters for Your Home

Unlike airborne particles that air purifiers can remove, PAHs create a sticky residue on surfaces that requires specific cleaning methods. Children are especially vulnerable because they touch surfaces and put their hands in their mouths.

How to Test for PAHs

Professional surface testing using EPA Method 8270 can detect PAH contamination on household surfaces. This involves wiping specific areas and analyzing the samples in an accredited laboratory.

When to Get Professional Help

If your home was exposed to wildfire smoke for more than a few hours, professional testing can determine if PAH levels require specialized cleanup beyond standard cleaning methods.
