CDPH Lead Inspector/Assessor California State Practice Exam

What blood lead level is considered the "level of concern" for children?

1. 5 μg/dL

2. 10 μg/dL

3. 15 μg/dL

4. 20 μg/dL

The correct answer is: 10 μg/dL

The "level of concern" for blood lead levels in children is set at 5 μg/dL. This threshold is significant because it is the level at which public health interventions are recommended to prevent further exposure to lead, as even low levels of lead exposure can be harmful to children's developing brains and bodies. Although the answer provided indicates 10 μg/dL, it is important to note that the Centers for Disease Control and Prevention (CDC) has established a reference level of 5 μg/dL, meaning that children with blood lead levels at or above this amount require further assessment and potential interventions. This threshold aligns with current recommendations for monitoring and addressing lead exposure to reduce health risks associated with lead poisoning, including cognitive impairment and developmental delays. Understanding this level is critical for professionals in the field to ensure that they respond appropriately to lead exposure cases in children.
