The figures were seen on Sunday (8 November) at 7:40am on IQAir, the Switzerland-based air quality website.

IQAir provides a live, real-time index of how clean or polluted a city's air is.

Under its standards, a score of 0 to 50 is considered good, while 51 to 100 is considered moderate.

A score of 101 to 150 is considered unhealthy for sensitive groups, and 151 to 200 is considered 'unhealthy'.

A score of 201 to 300 is considered 'very unhealthy', and anything above 301 is considered 'hazardous'.
