Reduce Children's Lead & Chemical Exposure at Home

This guide shows you practical, low-cost ways to lower your children’s contact with lead, mercury, and other common household chemicals. You’ll learn where these hazards hide, how to remove or seal them, and how to change daily routines to reduce exposure. Start with the steps that match your home’s age and your family’s habits—every action helps.

What You’ll Need

HEPA vacuum cleaner (or a vacuum with a HEPA filter)
Damp microfiber cloths and mop
Lead test kits (available at hardware stores)
pH-balanced, fragrance-free household cleaner
Duct tape or painter’s tape (for sealing chipping paint)
Gloves and a dust mask (for cleaning or DIY work)
Trash bags for safe disposal of contaminated materials

Step-by-Step

Test for lead paint if your home was built before 1978. Use an EPA-recognized lead test kit on any painted surfaces, especially windows, doors, and baseboards. If you see chipping or peeling paint, assume it may contain lead until proven otherwise.
Seal or cover deteriorating lead paint. For intact paint, leave it alone. For chipping areas, apply a layer of duct tape or painter’s tape over the damaged spot temporarily, then plan to have a certified lead abatement contractor remove it. Do not sand or scrape lead paint yourself—this creates toxic dust.
Wet-wipe and mop frequently. Lead dust settles on floors and windowsills. Use a damp cloth or mop with a household cleaner (not dry dusting, which spreads dust). Wipe windowsills, floors, and any surfaces children touch at least weekly, and more often if you live near busy roads or older industrial sites.
Use a HEPA vacuum for carpets and upholstery. A vacuum with a HEPA filter traps fine lead dust instead of blowing it back into the air. Vacuum high-traffic areas twice a week, and consider replacing wall-to-wall carpeting if it’s very old or stained, as it holds dust deeply.
Remove shoes at the door. Lead and other chemicals attach to shoe soles from soil and street grime. Keep a shoe rack or basket by the entrance and have everyone (including visitors) take off shoes. If you have a mat, use a washable one and clean it weekly.
Wash hands and toys regularly. Children put hands and toys in their mouths, which is how most lead dust gets ingested. Wash hands with soap and water before eating and after playing outside. Clean toys with warm water and mild detergent weekly.
Run cold water for drinking and cooking. Lead can leach from old pipes and solder. Use only cold tap water for drinking, cooking, and making baby formula. Run the tap for 30–60 seconds until it’s cold, especially if the water hasn’t been used for a few hours.
Check for mercury in old thermometers and switches. Replace old mercury fever thermometers with digital ones. If you have a thermostat or light switch that contains mercury (older models), replace it with a digital or electronic version. Never throw mercury items in the trash—take them to a hazardous waste collection site.
Choose low-chemical furniture and flooring. When buying new items, look for solid wood, metal, or products labeled low-VOC (volatile organic compounds). Avoid pressed wood (particleboard) that contains formaldehyde. If you have old foam furniture, consider replacing it, as flame retardants can break down into dust.
Ventilate when using household chemicals. When painting, using solvents, or applying pesticides, open windows and use fans. Keep children out of the room until the smell has cleared. Store all chemicals in locked cabinets away from children’s reach.
Test your soil if you garden or have bare dirt. Lead in soil comes from old paint chips, car exhaust, and industrial fallout. Have your soil tested by a certified lab. If lead is high, cover bare soil with grass, mulch, or paving, and plant vegetables in raised beds with clean soil.
Use fragrance-free, simple cleaning products. Many scented cleaners contain phthalates and other chemicals. Choose products with few ingredients, or make your own with vinegar and baking soda (but don’t mix them). Avoid air fresheners and aerosols—open windows instead.

Common Mistakes

Dry sweeping or dusting. This stirs up lead dust into the air where it can be breathed in. Always use a damp cloth or mop.
Sanding or scraping lead paint yourself. This creates extremely hazardous dust that can spread throughout the home. Leave it to professionals.
Using hot water for drinking or cooking. Hot water dissolves lead more quickly from pipes. Always use cold water.
Forgetting to wash children’s hands after playing outside. Soil can contain lead and other contaminants. Make handwashing a routine.
Ignoring old foam furniture. Old foam can break down and release flame-retardant dust. Replace or cover with a tight-weave fabric.

Tips

Focus on high-risk areas: windowsills, floors, and soil. These are the most common sources.
If you live in an older home, consider hiring a certified lead risk assessor to do a full inspection.
Wash children’s pacifiers and bottles frequently, and replace them if they show wear.
When buying toys, choose solid wood, cloth, or unpainted items. Avoid cheap plastic toys from unknown sources.
Use a doormat that is at least 3 feet long to catch more dirt.
Keep a pair of indoor-only slippers for children to wear inside.

Troubleshooting

What if I can’t afford to replace old windows or carpet? You can still reduce exposure by wet-wiping windowsills weekly and using a HEPA vacuum on carpets. Covering chipping paint with tape is a temporary fix. Many local health departments offer free lead testing and assistance programs.

What if my tap water test shows lead? Immediately use only bottled or filtered water for drinking and cooking. Look for a filter certified to remove lead (NSF/ANSI 53). Contact your local water utility—they may provide free testing or replacement of lead service lines.

What if my child has already been exposed? Talk to your pediatrician about a blood lead test. The most important thing is to stop further exposure. Wash hands frequently and keep your home dust-free. Most children with low-level exposure recover without treatment.

What if I can’t find a lead-safe contractor? Contact your state or local health department for a list of certified abatement professionals. You can also ask for “lead-safe work practices� from any contractor, which include using HEPA vacuums and containing dust.

Frequently Asked Questions

How do I know if my child has lead poisoning?

Lead poisoning often has no symptoms. The only way to know is a blood test. Ask your pediatrician about testing at ages 1 and 2, or if you live in an older home.

Is it safe to use a microwave to heat baby formula?

Yes, but never heat formula in the bottle—it can create hot spots. Heat water in a separate container, then mix with powder. Use cold water from the tap to avoid lead.

Are non-stick pans safe?

Modern non-stick pans are generally safe if not overheated. However, if the coating is scratched or peeling, replace it. For extra safety, use stainless steel or cast iron.

Can houseplants help reduce indoor chemicals?

Some plants can absorb certain VOCs, but they are not a substitute for ventilation and cleaning. They also can’t remove lead or mercury dust.

How often should I mop floors?

At least once a week in high-traffic areas, and more often if you have young children who crawl or play on the floor. Use a damp mop with plain water or a mild cleaner.

Should I worry about lead in old painted toys?

Yes, especially if the toys are from before 1978 or from other countries. If you’re unsure, test them with a lead swab kit or simply discard them.
