The air in South African Highveld cities smells foul in the winter: here’s why

Posted on June 22, 2022

Associate Professor Rebecca Garland recently published an article which explains why the air in South African Highveld cities smells foul in the winter. Gauteng Province, which is situated on the Highveld, is also South Africa’s industrial heartland where pollution levels are often unacceptably high.

In Gauteng, when the air comes from the east or the southeast where most industries are located, residents can sometimes smell the pollution. In Johannesburg, this generally happens when winds are from east to the south. They can bring in hydrogen sulphide (H₂S), which smells like rotten eggs.
