Lead toxicity

Lead toxicity is a multi-system pathological state caused by the absorption and systemic accumulation of the toxic heavy metal lead

It affects both children and adults, though pediatric populations are particularly vulnerable to neurodevelopmental damage Pathophysiologically, lead mimics divalent cations such as calcium, binds to sulfhydryl-containing proteins, and disrupts enzymatic processes—notably inhibiting delta-aminolevulinic acid dehydratase and ferrochelatase in the heme synthesis pathway Clinical manifestations vary with exposure duration and blood lead concentration, ranging from insidious neurocognitive deficits,...

It affects both children and adults, though pediatric populations are particularly vulnerable to neurodevelopmental damage

Pathophysiologically, lead mimics divalent cations such as calcium, binds to sulfhydryl-containing proteins, and disrupts enzymatic processes—notably inhibiting delta-aminolevulinic acid dehydratase and ferrochelatase in the heme synthesis pathway

Clinical manifestations vary with exposure duration and blood lead concentration, ranging from insidious neurocognitive deficits, fatigue, and microcytic anemia to acute lead colic, peripheral motor neuropathy, chronic nephropathy, encephalopathy, and seizures
