Research by City Hall found that air pollution levels are also higher in deprived areas or areas with a higher proportion of people of non-white background.
However, the study also found that nitrogen dioxide exposure has dropped by an average of 20 per cent across London since 2016, while exposure to particles such as dust, mascara or smoke has fallen by an average of 15 per cent.
This comes at a time when London Mayor Sadiq Khan has made cleaning the air in London one of his key policies. The city’s Ultra Low Emission Zone (ULEZ) will be expanded later this month.
Once the expansion is complete, approximately 3.8 million Londoners will remain within the ULEZ.
City Hall estimates that 100,000 cars, 35,000 vans and 3,000 lorries will fail to operate within the currently expanded ULEZ.
Generally, petrol cars purchased before 2006 and most diesel cars purchased before September 2015 fall below the emission standard.
Drivers of vehicles weighing less than 3.5 tonnes are charged 12. 12.50 per day within the zone, while drivers of non-compliant vehicles weighing more than 3.5 tonnes, including coaches and lorries, will have to pay 100 100 per day.
As part of the initiative, City Hall has launched its new Breath London Community Program.
The initiative invites community organizations from disadvantaged areas to install free air quality sensors in one of the 60 areas to choose from.
The sensors will then provide “real-time, hyper-local data” on air quality.
Londoners can also buy sensors for a fee.
The Breath London Network will be managed by the Environmental Research Group at Imperial College London and will be funded by the Mayor of London and Bloomberg Philanthropy.
Mr Khan said: “We know that toxic air pollution in London prevents the development of children’s lungs and worsens chronic diseases such as asthma.
“Our new research now confirms that people with the worst air pollution are more likely to live in deprived areas of London and in black, Asian and minority ethnic communities.
“The bold action I have taken since becoming mayor has reduced that gap by 50 per cent, but there is still a long way to go. That’s why I want to send air pollution to the history books in London.” Be more determined than ever to make every effort to do so.
“The expansion of the world’s first” ULEZ “will help us provide a cleaner, greener and cleaner city,” Meyer said.
A YouGov poll in April 2019 found that 72% of Londoners supported the introduction of ULEZ.
