Lead Poisoning Prevention

Who We Are

The Chicago Department of Public Health (CDPH) works to detect and address exposures to lead hazards. Through strategic inspections and abatement, as well as public education campaigns and testing, CDPH is leading efforts to permanently eliminate lead exposure to children.

As a result, the number of children with elevated lead levels has declined from one in four tested in the late 1990s to less than one in 100 today.

What We Do

Childhood Lead Poisoning Prevention Program

Program Targeting

The elimination of lead poisoning among children, pregnant women, and nursing mothers using intervention methods such as lead testing, lead environmental inspection, and case management and lead remediation and abatement.

Case Management

Children with a confirmed elevated blood level of at least 5 micro/deciliter are referred to the case management unit. Public Health Nurse will meet with the family to conduct a social developmental assessment, provide nutritional counseling, coordinate with the lead inspector, and refers the child for additional services as needed.

Environmental Inspection

A Licensed Lead-Risk Assessors inspects the interior/exterior of the residence of where a child has received a confirmation a positive lead blood test. The risk assessor inspects the home environment to find the source of how the child became lead poisoned.


Assures that property owners have the lead hazards removed by enforcement of the city and state lead laws via the court system.

Healthy Homes Grant Program

To assist qualified home or property owners with the removal or mediation of lead hazards which can be costly.

Community Engagement

Provided educational outreach about lead poisoning prevention to local communities.

Healthy Homes

"Healthy Homes" is a century-old concept that promotes safe, decent, and sanitary housing as a means for preventing disease and injury.

Healthy Homes is a HUD program that seeks to prevent disease among children that stem from being exposed to various types of environmental hazards in the home, such as lead, mold, allergens, and asthma. There is a lot of emerging scientific evidence linking health outcomes such as asthma, lead poisoning, and unintentional injuries to substandard housing. There are more than 6 million substandard housing units nationwide, and we would like to empower every family with the tools and education to better their homes regardless of the age of the home.

All homes regardless of whether they are new or old can contain hazards. Giving your home a regular check-up can help you ensure and maintain the health of your home. A healthy and safe home promotes the healthy growth and development of your family and can reduce healthcare costs. Just as every person needs regular checkups, so do our homes. Give your home a checkup to ensure that your home is a healthy, happy home!

Help Yourself to a Healthy Home provides valuable information to assist in making your home healthier and free of hazards for you and your family.

The Effects of Lead Exposure

Exposure to lead can seriously harm a child’s health and cause well-documented adverse effects.

Adverse effects can include:

  • Damage to the brain and nervous system
  • Slowed growth and development
  • Learning and behavior problems
  • Hearing and speech problems

This can cause:

  • Lower IQ
  • Decreased ability to pay attention
  • Underperformance in school

There is also evidence that childhood exposure to lead can cause long-term harm. Lead exposure in children is often difficult to see. Most children have no obvious immediate symptoms.

If there’s suspicion that a child may have been exposed to lead, parents should talk to their child’s healthcare provider about getting a blood lead test.

Many private insurance policies cover the cost of testing for lead in the blood. The cost of blood lead testing for children enrolled in Medicaid is covered by the Centers for Medicare & Medicaid services.

Take these steps to make your home lead-safe:

  • Talk with your child’s doctor about a simple blood lead test. If you are pregnant or nursing, talk with your doctor about exposure to sources of lead.
  • Talk with your local health department about testing paint and dust in your home for lead if you live in a home built before 1978.
  • Renovate safely. Common renovation activities (like sanding, cutting, replacing windows, and more) can create hazardous lead dust. If you’re planning renovations, use contractors certified by the Environmental Protection Agency (visit www.epa.gov/lead for information).
  • Remove recalled toys and toy jewelry from children and discard as appropriate. Stay up-to-date on current recalls by visiting the Consumer Product Safety Commission’s website: www.cpsc.gov.

What is Lead?

Lead is a highly toxic metal that may cause a range of health problems, especially in young children. When lead is absorbed into the body, it can cause damage to the brain and other vital organs, like the kidneys, nerves and blood.

Lead may also cause behavioral problems, learning disabilities, seizures and in extreme cases, death. Some symptoms of lead poisoning may include headaches, stomach aches, nausea, tiredness and irritability. Children who are lead poisoned may show no symptoms.

The health effects of exposure are more harmful to children less than six years of age because their bodies are still developing and growing rapidly. Young children also tend to put their hands or other objects, which may be contaminated with lead dust, into their mouths, so they are more likely to be exposed to lead than older children.

Sources of Lead Hazard Exposure

Lead can be found throughout a child’s environment in some of these places:

  • Homes built before 1978 (when lead-based paints were banned) probably contain lead-based paint. When the paint peels and cracks, it makes lead dust. Children can be exposed to lead when they swallow or breathe in lead dust.
  • Certain water pipes may contain lead.
  • Lead can be found in some products such as toys and jewelry.
  • Lead is sometimes in candies or traditional home remedies.
  • Certain jobs and hobbies involve working with lead-based products, like stain glass work, and may cause parents to bring lead into the home.
  • Children who live near airports may be exposed to lead in air and soil from aviation gas.
