Asthma danger zones

  • Cities with sulphur-heavy gases, few trees and many anthracite or coal stoves such as Soweto and Durban.

  • Near industrial areas where unhealthy gases are released into the air. These include the oil refineries near Sasolburg and Milnerton in Cape Town and chemical plants near Durban.
