Lead Absorption and Distribution

Systemic Distribution After GI Absorption

• Once absorbed from the GI tract, lead enters the bloodstream, as measured by blood lead level, according to Praxis Medical Insights 1, 2
• Lead then distributes to bone, brain, kidney, and other tissues where it exerts toxic effects, as reported by Environmental Health Perspectives 3
• Lead can be mobilized from maternal bone during pregnancy and lactation, representing an internal source of exposure, as documented by Environmental Health Perspectives 4, 5
