the zambian cities series: kabwe part two β the lead crisis and what kabwe is becoming
black mountain and what it is: on the edge of kabwe's residential areas, within walking distance of homes, schools, and playgrounds, is a structure locals call black mountain. it looks like a natural hill. it is not. it is a man-made pile of mine waste β crushed rock from nearly ninety years of lead and zinc mining. every footstep sends a puff of dust into the air containing lead, zinc, cadmium, vanadium, and other toxic heavy metals.
the scale: a 1975 study found soil lead concentrations as high as 9,400 parts per million in nearby townships β against the US EPA threshold of 400 ppm. the overwhelming majority of children living near the former mine have elevated blood lead levels. approximately half have levels requiring urgent medical attention. the blacksmith institute identified kabwe as one of the ten most polluted places in the world. in march 2022, the UN special rapporteur formally identified kabwe as a "sacrifice zone."
the knowledge was not absent: in the early 1970s, zambian doctors began seeing children admitted with convulsions and comas. a 1975 study documented the contamination precisely. the mine's own management had been monitoring worker lead levels and "leading out" β transferring workers to safer areas β since at least 1969. the knowledge that the mine was poisoning its surrounding communities was available. the mine continued to operate for another nineteen years.
the legal fight: in 2020, a class action was filed in south africa on behalf of approximately 100,000 kabwe residents against anglo american south africa. one of the largest environmental litigation cases in african legal history. as of 2026, continuing through the south african courts.
the remediation: approximately 5 million tonnes of mine tailings remain on the site. the zambian government licensed reprocessing of this waste by jubilee metals β a commercial arrangement critics note risks re-releasing contamination that had partially settled.
what kabwe is becoming: population 288,598 (2022 census). headquarters of zambia railways. home of mulungushi university. an agricultural hub. the zambia-china mulungushi textiles plant.
kabwe is the city where zambia's independence was born, where one of humanity's oldest known ancestors was found, and where the extractive industries' most visible unresolved debt to the communities that hosted them lives. the lead crisis is not a closed chapter.
the zambian cities series continues. πΏπ²π
