National Blood Lead Surveillance System

The National Blood Lead Surveillance System (NBLSS) is a program in the United States that monitors lead levels in people's blood, particularly in children. Lead exposure can cause serious health problems, including developmental delays and learning difficulties. The NBLSS collects data from various health departments and laboratories to track lead poisoning trends, identify high-risk areas, and inform public health strategies. By understanding where and how lead exposure occurs, the system helps to protect children's health and reduce lead-related risks in communities across the country.
