Lead Paint Dust is a critical-severity indoor air quality hazard that the EPA classifies as requiring immediate action. It is most commonly found in bedroom, living-room, nursery and originates from peeling paint, paint dust from renovation, window sills and frames.
Lead paint was banned in 1978 but remains in millions of homes. Sanding, scraping, or peeling paint releases lead dust that causes irreversible brain damage in children. There is no safe level of lead exposure.

クイックリファレンスデータ
| Hazard | Lead Paint Dust |
| EPA Severity | CRITICAL |
| Common Sources | peeling paint, paint dust from renovation, window sills and frames, door frames, porches, stair railings |
| Affected Areas | bedroom, living-room, nursery, kitchen, hallway, dining-room, sunroom, basement |
| Health Symptoms | developmental delays in children, learning disabilities, irritability, abdominal pain, seizures (high levels), anemia |
| EPA Recommendation | Test for lead before any renovation in pre-1978 homes. Hire EPA-certified lead-safe renovators. Do not sand or scrape paint without proper containment. Wash children's hands frequently. Use HEPA vacuums. |
Your Children Breathe 20,000 Liters of This Air Every Day
Kids breathe more air per pound of body weight than adults. Their lungs are still developing. If lead paint dust is in your home, they're getting a higher dose than you are. You childproof cabinets and plug outlets — but have you checked what they're breathing?
⚠️ The EPA estimates indoor air can be 2–5× more polluted than outdoor air. Your family breathes 20,000 liters of indoor air every day.
If lead paint dust is present, every breath could be doing damage you can't see or feel — until it's too late.

📋 Our Testing Methodology
Hazard severity classifications follow the EPA's Indoor Air Quality assessment framework:
- • Critical: Immediate health risk — evacuate and contact emergency services
- • High: Chronic exposure risk — test within 1 week, remediate within 30 days
- • Moderate: Potential risk — test to confirm, address if confirmed
Product recommendations are based on published detection accuracy, third-party test results, and EPA-recommended testing methods. Updated May 2026.

If your home has lead paint dust, there's a chance it also has asbestos fibers. Both can thrive in the same conditions. When you test for one, check for the others too.
関連する危険
Asbestos Fibers
Asbestos causes mesothelioma, lung cancer, and asbestosis. Homes built before 1980 likely contain asbestos in insulation, floor tiles, and pipe wrapping. Disturbing it releases deadly fibers into the air.
Lead Paint Hazards
Lead dust from deteriorating paint in pre-1978 homes. Especially dangerous to children. Even low-level lead exposure causes irreversible neurological damage, learning disabilities, and behavioral problems. There is no safe blood lead level for children.
Polychlorinated Biphenyls (PCBs)
Persistent chemicals in old fluorescent light ballasts and caulking. Hormone disruption risk. PCBs were banned in 1979 but remain in older building materials. They do not break down easily and accumulate in the body over time, disrupting endocrine and immune function.
Tap Water Safety
Municipal tap water is regulated but not necessarily free of contaminants. Lead from aging pipes, PFAS forever chemicals, chlorine byproducts, and agricultural runoff can all be present at levels that pose health risks — especially for children and pregnant women.
鉛塗料の粉塵と関連リスクの比較
Lead Paint Dust is classified as CRITICAL — the highest severity tier for indoor air hazards. Of the 4 related hazards we track, 3 carry a lower severity rating. This means lead paint dust should be your top testing priority if you suspect any indoor air quality issue.
Both Lead Paint Dust and Asbestos Fibers carry the same critical severity classification. Their combined presence in your home creates a compounding effect that exceeds the risk of either alone. Both are commonly found in basement, kitchen, hallway. Addressing one without testing for the other leaves a blind spot in your home's air quality.
Shared locations: basement, kitchen, hallway, living room
Lead Paint Dust poses a higher immediate risk than Lead Paint Hazards. While both require attention, lead paint dust is classified as critical severity versus lead paint hazards's high rating. If you test for one, the EPA recommends testing for the other simultaneously — they share common areas like bedroom, living room, nursery.

鉛塗料の粉塵の検査結果の意味
After testing for lead paint dust, you'll receive a measurement or a positive/negative result. Here's how to interpret what that number means for your home and family.
No Detection / Clear
No lead paint dust was detected in your test. Your home is currently clear of this specific hazard.
What to do: Re-test annually or after any renovation, water damage, or structural change. Lead Paint Dust can appear at any time due to peeling paint or paint dust from renovation.
Trace Detection
Trace amounts of lead paint dust were found. Even at low levels, a critical-severity hazard like this warrants prompt investigation of peeling paint, paint dust from renovation, window sills and frames.
What to do: Locate and eliminate the source immediately. Test for lead before any renovation in pre-1978 homes. If you cannot identify the source, contact a licensed professional.
Elevated / At Action Level
Your test shows elevated lead paint dust at or above the EPA action level. At this concentration, the health risk is significant and immediate steps are required.
What to do: Do not delay. Test for lead before any renovation in pre-1978 homes. Contact a licensed remediation professional within 24 hours. Evacuate if you experience developmental delays in children or learning disabilities.
Interpretation guidelines are based on EPA standards for chemical hazards. For lead paint dust, test for lead before any renovation in pre-1978 homes. Always confirm results with a certified professional.
鉛塗料の粉塵について住宅所有者がよく聞く質問
What are the symptoms of lead paint dust?
Common symptoms of lead paint dust include: developmental delays in children, learning disabilities, irritability, abdominal pain, seizures (high levels), anemia. If you are experiencing these symptoms, test your home and consult a healthcare provider.
How do I test my home for lead paint dust?
Common sources include: peeling paint, paint dust from renovation, window sills and frames, door frames, porches, stair railings. You can test using the products recommended above. Test for lead before any renovation in pre-1978 homes. Hire EPA-certified lead-safe renovators. Do not sand or scrape paint without proper containment. Wash children's hands frequently. Use HEPA vacuums.
Is lead paint dust dangerous to children?
Yes. Children are especially vulnerable to lead paint dust because their respiratory systems are still developing and they breathe more air per pound of body weight than adults. Lead paint was banned in 1978 but remains in millions of homes. Sanding, scraping, or peeling paint releases lead dust that causes irreversible brain damage in children. There is no safe level of lead exposure.
Stop wondering.
Start knowing.
The data is clear. The next step is testing.
The EPA notes that lead paint dust can only be confirmed through testing — it's often invisible and odorless. A test kit or monitor gives you a real number instead of a guess.
