Emergency toxic air alert issued in London
The mayor of London, Sadiq Khan, has warned of a "public health emergency" as soaring temperatures combined when southerly winds are expected to cause dangerously toxic air and high levels of pollution today and tomorrow.
Mr Khan has triggered the Capital’s emergency air quality alert which will see warnings displayed on the underground, road signs and at bus stops.
Air pollution is set to hit a 'high peak' in central parts of London, particularly near the busiest roads.
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 34 degrees centigrade in the late afternoon (Wednesday).
High air pollution is forecast today – alerts are live at bus stops, tube stations & roadsides across the capital https://t.co/REyG3VWhQQ— Mayor of London (@MayorofLondon) June 21, 2017
