Sasolburg's air quality faces serious challenges from the Sasol synthetic fuels and chemicals complex, one of South Africa's most significant industrial emission sources generating elevated SO₂, benzene, and industrial PM2.5 from the coal-to-liquids operation. Winter Highveld temperature inversions concentrate Sasol's industrial plume and vehicle emissions across the Vaal River corridor, making Sasolburg one of South Africa's most persistently industrially impacted urban communities throughout the dry season.

When is air pollution at its worst in Sasolburg?
Air quality at Sasolburg is most likely to dip during the dry winter months from May to August, when temperature inversions trap vehicle and household emissions close to the ground on still mornings. Conditions improve markedly once the summer rains arrive from November, as stronger winds and regular thunderstorms clear the plateau air for the rest of the season.
Are air quality levels in Sasolburg based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
