London Mayor Khan Issues Air Quality Emergency Alert Amid Scorching Heatwave
The mayor of London, Sadiq Khan, has triggered the capital’s emergency air quality alert as soaring temperatures combined with southerly winds are expected to bring dangerously toxic air to large parts of England and Wales on Wednesday. The emergency alerts will see warnings displayed at bus stops, on road signs and on the underground.
A spokesman said: “Due to the continued warm and sunny weather conditions, high levels of pollution are forecast tomorrow, particularly near busy roads. As a result of this the mayor has triggered a London-wide air quality alert this afternoon on the transport system to ensure Londoners are fully aware and able to take any extra precautions needed.”
Air quality researchers at King’s College London issued a statement on Tuesday warning of high pollution levels as southerly winds bring in toxic air from the continent during the day. A Department for Environment, Food and Rural Affairs air quality analysis shows moderate or high pollution is likely to affect large parts of England and Wales on Wednesday.
Experts warn that anyone with lung or heart problems should avoid or reduce strenuous physical exertion, particularly outdoors. Older people or those with asthma should take particular care. They say the worst air quality in the capital is likely to coincide with temperatures of 34C in late afternoon.
