Lead Facts & Testing

Lead can be harmful to anyone, but it’s especially dangerous for babies and young children. The most common risk comes from homes built before 1978, when lead-based paint was still widely used. 

Where Lead Can Be Found

• Old paint, dust, or soil around your home
• Drinking water from older plumbing pipes
• Imported items like pottery, toys, jewelry, makeup, foods, or medicines

Why is lead a problem?

  Even small amounts of lead can affect children’s health and development. Possible effects include:

• Trouble with learning and behavior
• Slower growth and development
• Damage to the brain and nervous system
• In very high amounts, serious illness

The Christian County Health Department offers rapid lead testing so families can get quick answers and peace of mind. 

• A blood lead level above 3.5 micrograms per deciliter (µg/dL) is considered a cause for concern. 
• There is no safe level of lead. Even small amounts can be harmful, especially to children.

• Follow-Up Testing – Confirming blood lead levels through additional testing.
• Environmental Exposure Review – Identifying possible sources of lead in your child’s daily environment.
• Nutritional Guidance – Offering tips on healthy eating, including calcium and iron-rich foods that can help reduce lead absorption.
• Environmental Investigation – Coordinating an in-home investigation to find and eliminate lead hazards
