Elevated Blood Lead Program

All children should receive blood lead screening during routine well-child visits to their providers at 12 and 24 months old. Elevated blood lead levels are reported to the Maryland Department of the Environment, who then notifies the child’s local Health Department. 

When a child in Howard County is identified as having an elevated blood lead level, the Health Department works with the pediatrician and family to help identify the source of lead exposure and remove it from the child’s environment. The Health Department can educate families, provide case management, coordinate recourses, and in some cases collaborate with Maryland Department of the Environment to conduct home inspections. Health Department staff follows children with elevated lead levels until their lead level has dropped below the level of concern identified by the Centers for Disease Control and Prevention (CDC). 

For questions or more information, call the Howard County Health Department at: 410-313-7500 or toll free at 1-866-313-6300.

Frequently Asked Questions about Lead Poisoning

What is lead poisoning?

Lead poisoning occurs when lead enters the body through contaminated air, food, water, dust, or soil and builds up in the blood and soft tissue. Anyone can have lead poisoning, but children are more at risk because they are more likely to chew non-food items, more likely to get lead dust on their hands, and they absorb lead more easily than adults. Most children with increased lead levels in their blood do not have any obvious symptoms and only find out they have been exposed to lead during routine screening. Even low levels of lead can have negative effects over time, especially on mental and physical development.
