High levels of air pollution in Johannesburg in winters and the rising exhaust emissions on its roads has prompted the city to adopt stringent air-quality measures.
Atmospheric scientist Margot Richardson, who works in the city's department of development planning, transportation and environment, said that tests in Johannesburg during winter found 180 microgrammes a cubic metre of particulate matter in the air, way above international standards of 75 microgrammes a cubic metre.
Richardson claims fossil fuel burnt in coal stoves for domestic heating was largely responsible for the pollution. These, she added, lead to a range of respiratory and heart problems, particularly among the young and the elderly.
