Nigerian Children Dying of Lead Poisoning From Gold Mining in Latest Outbreak

Illegal grinding of ore releases lead dust that contaminates air, water and food

In 2010, Nigerian men walked among the graves of children killed by lead poisoning caused by illegal gold mining. Now more children are dying in another outbreak in the country’s Niger state

LAGOS, Nigeria—More than two dozen children have died of lead poisoning from illegal gold mining in a remote west-central village, Nigerian health officials said, while doctors are still treating thousands from an earlier outbreak.

In the most recent poisonings in the Rafi area of Niger state, dozens more children are sick and action must be taken quickly if they are not to suffer irreversible neurological damage, said Michelle Chouinard, Nigerian director for Doctors Without Borders, on Friday.

The grinding of ore releases dust highly contaminated with lead. Children are exposed to the dust when they work in the processing, or when relatives return home covered in the dust, or when processing occurs at home. Children are also exposed to the lead through water or food.

Ms. Chouinard’s organization still is treating children from a 2010 mass lead poisoning, in Zamfara state, that killed 400 children and left many paralyzed, blind and with learning disabilities because of a three-year delay in government funding for a cleanup.

Ms. Chouinard said they have cured 2,688 of 5,451 people infected and hope to complete treatment next year. They have had most success in the worst-affected village of Bagega, where all but 189 of 1,426 people have had the lead leached from their bodies.

Junior Health Minister Fidelis Nwankwo said Thursday all those newly infected in neighboring Niger state are under 5 years old, with nearly half of the 65 sickened children dying.

“The devastating impact of this outbreak is associated with new mining sites which were found to contain more leaded ores, which are often brought home for crushing and processing,” he said.

Previous government efforts to forbid artisanal mining have failed as poor villagers make up to 10 times as much from gold than from farming.

In Zamfara state, where the processing area was found to contain over 100,000 parts per million of lead—the United Nations considers 400 parts per million safe—Idaho-based TerraGraphics International Foundation spent nearly six months cleaning up and training villagers in safer mining.

The training “is working fairly well and I think it’s one of the contributing factors to why the number of patients is decreasing so much and so quickly in Bagega,” Ms. Chouinard said.
