At what venous blood lead level is local health department intervention required?

The correct intervention level for venous blood lead concentration is typically set at 20 micrograms per deciliter (ug/dL) in many public health guidelines. At this level, health departments are mandated to take action to reduce lead exposure and protect the health of individuals, particularly children. Interventions may include further testing, environmental assessments, and providing recommendations for lead removal or reduction in exposure.

Recognizing the blood lead level at which intervention is necessary is crucial for mitigating health risks associated with lead exposure, which can lead to significant developmental and health issues, especially in young children. Therefore, the 20 ug/dL threshold serves as a critical point for public health measures aimed at preventing lead poisoning.
