Research published in the Lancet last week found that local people working in mines in the African “copperbelt”, a mining region stretching across Zambia and the DRC, are at significantly higher risk of having children born with serious birth defects.
Researchers from the University of Lubumbashi in the DRC and the universities of Leuven and Ghent in Belgium found that the risk of birth defects greatly increased when a parent worked in a copper and cobalt mine.
The researchers linked the increased risk to the high levels of toxic pollution caused by the extraction of cobalt in southern Katanga, named one of the 10 most polluted areas in the world.
The study was commissioned after academics at the University of Leuven read reports from local doctors, NGOs and local authorities of high numbers of children of miners in the DRC being born with conditions such as limb abnormalities, cleft palates and neural tube defects such as spina bifida.
"Every day tens of thousands of workers are exposed to heavy work with a lot of pollutants and dust. The health of the miners and their families must be taken into account by anyone who profits from or uses cheap smartphones around the world,” said Dr Daan Van Brusselen, a paediatrician at Ghent University who worked on the study alongside doctors in Belgium and the DRC.
Earlier this year a lawsuit was launched in the US, which accused the world’s largest technology companies of aiding and abetting in the deaths of children working in mines in the DRC. The case is ongoing.
