Is lead paint in old homes still a risk for children?

What's actually in it

Lead is a heavy metal that was commonly used in household paint before it was banned. In older homes, this paint can chip, peel, or turn into dust that children breathe in or swallow. It is not just paint that poses a threat: lead can also be found in other household items, such as certain types of glazed pottery that leach the metal into food, according to a 2026 study in J Public Health Manag Pract.

Once lead enters the body, it does not leave easily. It often settles in the system alongside other toxic metals like cadmium. These substances can build up in the home environment, creating hidden risks for families, as noted in a 2026 study in Environ Int.

What the research says

The science is clear: lead exposure is harmful to child development. A 2026 study in Front Nutr found that when children are exposed to both lead and cadmium, they face a higher risk of severe social deficits, particularly those already diagnosed with autism spectrum disorders.

Because lead persists in the environment of older homes, it remains a constant threat. This is not just a historical problem. Peer-reviewed research shows that the presence of these chemicals in our living spaces directly impacts the health and long-term well-being of children.
