Residents mull source of pong

People have been reporting strong sulphur odours causing headaches and eye irritation. The city is monitoring air quality while authorities investigate potential Highveld emissions

In recent years, research Wright and colleagues led has highlighted how prolonged heat exposure places outdoor workers, children, older people and low-income communities at increased risk of dehydration, heat stress, respiratory illness and other adverse health outcomes. The risks are expected to intensify as temperatures continue to rise. (Envato Elements)

Why our changing climate is bad for your health

The Earth is getting hotter and extreme weather events are becoming more common. It’s bad news for all aspects of our lives

Projects like the Medupi and Kusile (above) power stations, which experienced extended timelines and higher-than-planned costs, highlight the complexities involved in large-scale infrastructure delivery within parts of South Africa’s public sector

Eskom plan to drop Kusile pollution controls is ‘destructive, deadly’

Activists say the deaths of vulnerable people is too high a price to pay for electricity when alternatives are available

Eskom’s Kusile pollution rules exemption to ease blackouts threatens health

The exemption will have a major effect on people’s health, say environmental justice groups

With two units at Koeberg nuclear power station likely to be out of commission at the same time, Eskom will struggle to keep the lights on, said Electricity Minister Kgosientsho Ramokgopa.

Debt-ridden Eskom faced with ‘complex issues’ in its just transition to clean energy

Shutting down Eskom’s coal plants and shifting to cleaner technologies will bring ‘cleaner air’ to the polluted Mpumalanga Highveld, says the utility’s environmental manager

Big stink: Task team to investigate sulphur smell that choked parts of Gauteng, North West

Preliminary results show significantly elevated levels of hydrogen sulphide around the Irene monitoring station in Centurion on 7 June

Joburg’s big stink can lead to headaches and nausea

Sasol has said the levels of sulphur dioxide and hydrogen sulphide were below the limits prescribed by its atmospheric emissions licences

The Mail & Guardian reported in 2018 that Mpumalanga has the highest levels of air pollution in the world, topping nitrogen dioxide levels across six continents.  (Marco Longari/AFP)

What’s that smell? The legacy of polluted air floating into Gauteng

The province may be in for a heavy stench as the winds blow in from Mpumalanga. The M&G looks back at the events that contributed to this state of affairs

Load-shedding’s silver lining: Lower levels of sulphur dioxide air pollution

Analysis of Nasa data shows that although SO₂ emissions around the world have fallen by about 6%, the levels are high enough to harm the health of billions of people.

Elevated levels of sulphur dioxide emitted by Durban’s Engen refinery since it resumed operations last month, after it shut down when the Covid-19 lockdown started, have sparked a wave of respiratory illness and other health problems among residents of Wentworth and the Bluff. (John McCann/M&G)

South Durban chokes as Engen refinery starts up

Covid-19 brought clear skies when industries shut down, but then came what residents call waves of filthy air that made them sick

With two units at Koeberg nuclear power station likely to be out of commission at the same time, Eskom will struggle to keep the lights on, said Electricity Minister Kgosientsho Ramokgopa.

Air pollution death toll rises by 170

Eskom has said that it cannot afford to meet the legal levels and that some of its plants will need to run until the early 2030s.
