Fire Safety & Smoke Damage
Heavy Metals in Dust
Quick Definition
Lead, arsenic, and cadmium contamination in household dust from wildfire smoke, often above health guidelines
Heavy metals like lead, arsenic, and cadmium become concentrated in household dust after wildfire smoke exposure. These toxic metals can accumulate to levels far above health guidelines, especially in homes near burned structures.
What You Need to Know
When buildings and vegetation burn, heavy metals are released into the smoke and settle as dust throughout your home. Lead impairs children's IQ development, while arsenic and cadmium are known carcinogens that can cause long-term health problems.
Why It Matters for Your Home
Heavy metal dust is invisible but extremely persistent. Children are at highest risk because they play on floors and frequently put their hands in their mouths. These metals don't break down over time and require specific removal techniques.
How to Test for Heavy Metals
Professional dust testing using ICP-AES analysis (NIOSH 7301 method) can detect 12 different heavy metals in your home's dust. Samples are collected from surfaces where your family spends the most time.
When to Get Professional Help
If testing shows elevated heavy metal levels, professional remediation may be necessary. Standard cleaning often redistributes these particles rather than removing them effectively.
