Claim: Reports as recent as 2017 reported 92% prevalence of blood lead poisoning in children from some villages in the Nigerian state of Zamfara.

Q1: Was there high level of child lead poisoning in Zamfara State Nigeria 2017 ?
A1: The World Health Organization (WHO), which has been assisting the Government in managing the situation, called for Nigerian authorities to increase their commitment to combat lead poisoning by strengthening its capacity to diagnose, treat and manage it, as well as ensuring that all areas have been de-contaminated.

In a news release, WHO warned that lead poisoning cannot be successfully eliminated without significant changes to mining practices, including the relocation of ore processing activities and storage of ore materials away from villages.

Other necessary measures recommended by WHO include the adoption of processing methods that produce less dust, and hygiene measures such as removing contaminated clothes and washing before returning home.

Lead poisoning damages the nervous system and causes brain and blood disorders. Treatment is time-consuming and expensive as it involves undergoing long-term therapy with chelating agents, which remove heavy metals from the body.

Treatment also involves persuading people to adopt new practices and behaviours, something which requires an ongoing effort from authorities to continuously raise awareness and make sure the population follows preventive measures.

According to WHO, children in seven villages in Zamfara state require chelation therapy. This is in addition to the residents of seven other villages who have already received treatment. In these villages the combined effects of removing children from lead exposure and providing chelation therapy caused the child mortality rate to drop from 43 per cent to 1 per cent in one year.

Since the problem was discovered last year, $1.9 million has been provided by the UN Central Emergency Response Fund (CERF) to WHO and the UN Children’s Fund (UNICEF), which have been used to provide treatment, train doctors, provide quick diagnoses, and raise awareness about the hazards of lead.

Q2: Was there a 92% prevalence of blood lead poisoning in Zamfara  due to gold mining?
A2: No answer could be found.

Q3: What was the reason behind  high levels of child lead poisoning in Zamfara State Nigeria?
A3: Gold rush triggers deadly lead poisoning in Nigeria

Q4: Where did this figure come from?
A4: a 2013 study of 307 children below age six as the likely source of his claim. He said he may have mistaken this as being in 2017.

The study focused on a village in the Kawaye area of Anka local council in Zamfara. It recruited the children through random sampling to reduce bias. The researchers, who included the Ahmadu Bello University and the national and state health ministries,  found a 92.5% prevalence of lead poisoning, the same proportion as Abdulsalam’s claim.

Q5: How does this study define lead poisoning?
A5: The study based its definition of childhood lead poisoning on US Centers for Disease Control and Prevention (CDC) guidelines, which give this as blood lead levels of 5 micrograms per deciliter or more. 

Some 34 of the children had elevated blood lead levels of up to 45 micrograms per deciliter.

Q6: Do any other sources show similar results?
A6: Other studies also show high child lead poisoning levels in the state. In 2010, a deadly lead poisoning outbreak was reported in some areas of Zamfara. The state holds many of the gold mining leases in Nigeria.

In two of the most affected villages, 25% of children under age five had died in the past year.

Q7: What did studies of the children affected show?
A7: In two of the most affected villages, 25% of children under age five had died in the past year. One of the first studies into the outbreak, done in mid-2010, found that as many as  eight in 10 of them had convulsions before death.

The researchers tested 204 children below age 5 in the two villages. All had lead levels higher or equal to 10 micrograms per decilitre, with 97% of them having levels higher or equal to 45 micrograms per decilitre.

Q8: How dangerous is lower levels of lead in the blood?
A8: Even at low levels of 10 micrograms per deciliter or less, the immune, reproductive and cardiovascular systems of people are compromised by lead poisoning. In June 2010, a guideline value of an intake of 1 microgram per deciliter for lead was withdrawn after experts from the WHO and the Food and Agriculture Organization of the United Nations found it inadequate to protect against diminished intelligence. 

Prof Udoh, the pharmacology and toxicology expert from the University of Calabar, agreed that based on this revised standard, the lead levels found in the blood of all the children tested during the 2010 study were harmful.
