Lead, a naturally occurring heavy metal, is highly toxic in large amounts, especially for young children and pregnant women. Lead exposure can occur through inhalation, ingestion or skin contact and is found in many places, including in older homes, water pipes and soil. Once lead has been introduced to the human body, it is absorbed by the bloodstream and spread throughout the rest of the body, where it can affect other organs and tissues.

There is no known safe level of lead exposure. In 2021, the Centers for Disease Control and Prevention (CDC) lowered the blood lead reference value — the threshold for identifying unsafe levels of lead in the blood — to 3.5 μg/dL. Studies found that even low levels of lead, far below the previous threshold of 10 µg/dL, are detrimental to cognitive development in children and can negatively impact intellectual function, attention-related behaviors and academic and cognitive skills well into adolescence and adulthood

High blood lead levels during pregnancy can be passed onto the developing fetus, which may cause miscarriages, low birth weight infants, preterm births and other congenital disabilities. 

Housing built before 1978 carries an elevated risk for lead exposure, and housing built before 1950 has the highest risk of lead exposure. Due to a ban on lead-based paint in 1978, housing built after this year carries minimal risk. The United States Department of Housing and Urban Development estimated that 89% of the 34.6 million homes with lead paint were built before 1978.

A study of young children ages 6 months to 2 years found that interior renovation of older homes — which often includes painting, sanding, scraping or other activities that might release lead dust into the air — further increased risk of lead poisoning. Over 3 million homes with children younger than age 6 had one or more lead-based paint hazards in 2021, 2.1 million of which were low-income households. Investing in lead paint hazard control for communities at high risk could provide a return of $17-$221 in societal and health costs for each $1 spent.

Populations most vulnerable to environmental lead exposure include:

  • Children younger than age 6, who tend to put their hands on objects that may be contaminated with lead dust.
  • Low-income households. Among low income households, those without government housing assistance have a higher prevalence of lead-based paint hazards than those receiving housing assistance.
  • Those who live in the Northeast and Midwest regions, where the housing is older and has significantly higher levels of lead-based paint and lead-based paint hazards.

Strategies to reduce the negative consequences of lead exposure include:

The Association of Maternal and Child Health Programs maintains a Lead Poisoning Prevention Toolkit for agencies working to prevent lead exposure.

Healthy People 2030 has two objectives related to reducing lead exposure:

  • Reducing blood lead levels in children ages 1-5.
  • Reducing lead exposure among the population.

America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.

We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
