Gold ore was processed inside two-thirds of the family compounds surveyed. In multivariate modeling, significant risk factors for death in the previous year from suspected lead poisoning included the age of the child, the mother's work at ore-processing activities, community well as primary water source, and the soil lead concentration in the ...
The gold ore was heavily laden with lead which the children ingested care-freely. The Committee's mission was to see things for themselves, consult with relevant authorities in the state with a view to find a quick remediation of the area and bring succor to Bagega children.
Of particular concern is the town of Bagega in Anka Local Government Area, which is a regional hub for ore processing and the informal gold trade.
