Nigeria tops the least of countries in Africa where children are worst hit by high level of lead in their blood.
Africa is the worst-affected region after South Asia according to a new study.
The research postulates that a third of all children have high levels of lead in their blood, putting their mental and physical health at risk.
The UN children’s agency (Unicef) and the environmental group Pure Earth, warns about concentrations of lead in the body, which can be so high that they stop the development of the brain, heart and other vital organs.
Lead, according to medical analysis comes mainly from inadequately recycled waste, like batteries, and industries such as mining and open-air smelters.
African toxicologists not involved in the study said children across the continent work in car garages and informal electronic waste recycling sites, where they are dangerously exposed to lead.
In Ghana’s, 60% of lead poisoning reportedly comes from restaurant utensils’ that were made from scrapped aluminium.
Government official in Senegal said lead-based paints were also a major source of poisoning in children.
The report’s authors have called for urgent action to stop children being poisoned on what they say is a massive and previously unrecognised scale.
