Millions of vulnerable people in southern England and Wales have been advised to stay indoors because of unusually high levels of air pollution, and some parts of Brixton are also being impacted.
Talking to the Guardian, Prof Frank Kelly of King’s College London explained some of the health risks:
Periods of very high pollution in London arise usually because the city’s normal pollution emissions are increased further by polluted air arriving on light winds from neighbouring areas such as northern Europe.
However, whether home-produced or arriving from the continent, the tiny particles we take into our bodies with each breath cause immediate problems for some individuals, such as those with asthma, and contribute to longer-term problems for most of us in the form of heart disease and stroke.”

These views taken from central Brixton show the current levels of smog in the air.
