Lead Program Overview

Lead is a corrosion-resistant dense metal that is easily molded and shaped. 85% of lead in the US is used for lead-acid batteries, which are used in automobiles, as industrial-type batteries for standby power for computer and telecommunications networks, and for motive power.

What is Lead Poisoning?
Lead poisoning occurs when lead builds up in the body as a result of swallowing, ingesting, or inhaling lead dust, and/or lead-based paint chips.

Impact of Lead Poisoning
No amount of lead level is safe for children. Lead poisoning can cause developmental delays, behavioral problems, and adversely impact health.

The potential health impacts of lead poisoning include
  • Damage to the brain and nervous system
  • Slowed growth and development
  • Learning and behavior problems
  • Hearing and speech problems
These can then lead to
  • Lower IQ
  • Decreased ability to pay attention
  • Underperformance in school
Sources of Lead Exposure
  • Exposure to lead dust from certain job occupations such as battery manufacturers.
  • Exposure to lead dust from hobbies such as target shooting, and stained glasswork.
  • Non-paint sources: herbal or home remedies, imported spices (e.g., turmeric powder), ceremonial makeup (e.g., kohl), imported pottery, contaminated water lines.

Children can be poisoned when they swallow or breathe in lead dust. 2. cartain water pipes may contain lead. 3. lead can be found in some products such as toys and jewelry.  4. lead is sometimes found imported candles and traditional home remedies. 5.

  • Children should be tested at 12, 24, and 36 months of age.

Recommended Actions Based on Blood Lead Level

Blood Lead Reference Value

*Note: In 2021 the CDC updated its blood lead reference value (BLRV) from 5 micrograms (ug) per deciliter(dL) to 3.5 micrograms per deciliter, based on the 97th percentile of the blood lead level (BLL) distribution in U.S. children ages 1-5 years. The CDPH Lead Poisoning Prevention Program will at this time, in accordance with the Illinois Lead Poisoning Prevention Act, continue to observe 5 ug/dL as the highest risk for exposure to lead.

CDPH LEAD Program: What We do

Case Management
Environmental Inspection
Enforcement
Healthy Homes (HUD)
Community Engagement


Case Management: Children with a confirmed elevated blood lead level of at least 5 micrograms per deciliter are referred to the CDPH lead case management unit. A public health nurse will meet with family, conduct a developmental assessment, provide nutritional counseling, coordinate with a lead inspector, and make referrals for additional services as needed.

Environmental Inspection: Licensed lead inspectors inspect the interior/exterior of residences where a child has received an elevated blood level to determine if there are any lead hazards.

Enforcement: Property owners of properties that have been found to have lead hazards must have the lead hazards removed by a lead-certified contractor according to the City of Chicago ordinance.

Healthy Homes (HUD): The Chicago Lead Poisoning Prevention and Healthy Homes Program’s (LPPHHP) mission is to detect and address exposures to lead hazards. The LPPHHP assists low-income families who occupy pre-1978 privately-owned housing in the City of Chicago through the Lead-Based Paint Hazard and Reduction Grant

Community Engagement: The Chicago Lead Poisoning Prevention and Healthy Homes Program’s (LPPHHP) provides education to families, communities and other organizations such as childcare providers about lead poisoning prevention and testing.
