Nairobi’s air pollution sparks Africa health warning

Peak hour traffic on Tom Mboya Avenue, Nairobi, With Africa’s predicted rise in population – and a constant stream of dirty secondhand cars from Europe and Japan – this urban health crisis could kill 1.5 million within a generation

A minibus belches black smoke; the lorry behind it in the traffic jam billows white fumes. Eyes smart in the smog as diesel gases from thousands of 10 and 15-year-old vehicles fill Nairobi’s hazy evening air, adding to pollution levels that are “beyond imagination”, according to one resident.
