Zambia: Lead mining and smelting has poisoned generations of children in the Copperbelt town Kabwe, according to reports
'The world's most toxic town: the terrible legacy of Zambia's lead mines' 28 May, 2017
... Kabwe is the world’s most toxic town, according to pollution experts, where mass lead poisoning has almost certainly damaged the brains and other organs of generations of children – and where children continue to be poisoned every day.
Almost a century of lead mining and smelting has left a truly toxic legacy in the once-thriving town of 220,000 people in central Africa’s Copperbelt, 100km north of the capital Lusaka. But the real impact on Kabwe’s people is yet to be fully revealed and, while the first steps towards a clean-up have begun, new dangers are emerging as desperately poor people scavenge in the vast slag heap known as Black Mountain.
... The fumes from the giant state-owned smelter, which closed in 1994, has left the dusty soil in the surrounding area with extreme levels of lead. The metal, still used around the world in car batteries, is a potent neurotoxin and is particularly damaging to children. But it is youngsters who swallow the most, especially as infants when they start to play outside and frequently put their hands in their mouths.
... The slow, insidious nature of lead poisoning means careful epidemiological work is needed to distinguish its effects from other causes and reveal the true extent of the crisis.
... The blood levels of lead in children in Kabwe are also known to be very high - a recent study revealed that every one of 246 children tested were above the safety limit of 5 micrograms per decilitre of blood. The vast majority were over 45 micrograms per decilitre, which causes brain, liver and hearing damage, and eight were over 150 micrograms per decilitre, at which point death is the likely outcome.
