Mpumalanga hosts many of South Africa’s coal-fired power stations. Understanding what they emit — and how weather spreads it — helps residents interpret AQI readings in towns across the province and downwind areas.
Sulfur dioxide and coal combustion
Burning coal releases sulfur dioxide (SO₂), nitrogen oxides, and particulate matter. SO₂ can irritate airways and contributes to acid rain and secondary particle formation. High stacks disperse plumes, but calm conditions and inversions can bring pollutants back to ground level many kilometres away.
Industrial areas and monitoring
Ground monitors and models may show different results depending on wind direction. A “good” reading in one town does not guarantee clean air in another on the same afternoon. Watch dominant pollutants on your dashboard — PM2.5 and SO₂-related impacts often move together during stagnant weather.
- Note wind direction when readings spike.
- Limit outdoor activity for children on sustained high-AQI days.
- Follow official air quality alerts from environmental authorities.
