What are the permissible levels for children?

• A. 5 ug/dl
• B. 10 ug/dl
• C. 20 ug/dl
• D. 1 ug/dl

Answer: (A)

Children are especially vulnerable to lead, so health guidelines set a specific blood lead level that triggers actions to reduce exposure. The level used as the action threshold for children in this context is 5 micrograms per deciliter. When a child’s blood lead is at or above 5 μg/dL, public health actions—such as confirmatory testing, home investigations, and steps to reduce lead sources—are typically initiated. Levels below this threshold may still be of concern, but the 5 μg/dL mark is the established trigger for formal intervention in pediatric risk assessments.
