Which organization sets a lead blood level of concern at 25 ug/dL?

Which organization sets a lead blood level of concern at 25 ug/dL?

• A. NIOSH
• B. OSHA
• C. CDC
• D. EPA

Answer: (A)

In occupational health, action thresholds for blood lead guide when to start medical follow-up. The 25 μg/dL level of concern is a health-based trigger defined by NIOSH, the agency focused on occupational safety and health research and recommendations. This threshold is used to prompt medical evaluation and consideration of removing a worker from exposure when lead in the blood reaches that level, before regulatory removal limits are reached. OSHA sets enforceable exposure limits and medical surveillance criteria, but the 25 μg/dL level itself comes from NIOSH, not OSHA. CDC provides population health benchmarks, and EPA handles environmental concerns, but the specific 25 μg/dL action level for workers is a NIOSH designation.
