LEAD-POISONING IN CHILDHOOD

Epidemiological research has provided a better knowledge of lead poisoning effects on neuro-cognitive development of children. The increased sensitivity of screening biological tests and the decrease of the therapeutic threshold of intervention make primary prevention even more necessary. The oral route being responsible for the most severe morbidity of lead poisoning in children, screening must first specify the risk factors associated with oral lead absorption according to the age of children and local exposure to sources of lead.
