Air pollution is 31 times more deadly than car accidents in west London, according to recent figures.
Public Health England revealed on April 19 the proportion of deaths across the country that can be attributed to air pollution in any given year.
It said 6.9% of the total number of adult deaths were caused by air pollution in west London in 2013, the latest year for which data is available.
Given that 10,707 adults died in west London in 2013 this means that 736 deaths were attributable to the effects of air pollution, a figure 31 times higher than the 24 people who died in car accidents in the area that year.
These figures do not mean that air pollution was the sole cause of 736 deaths but rather that the role that air pollution played in all 10,707 deaths was equivalent to 736 deaths on its own.
Despite the high number of air pollution deaths across west London in 2013 the numbers are lower when compared with 2010.
These figures come a day after Greenpeace installed gas masks on several famous monuments in London in protest at high air pollution levels.
The figures 'highlight the gravity of the invisible threat to our lives'
It was also in the same week Plane Stupid protesters were fined for blocking a tunnel into Heathrow Airport .
A spokesperson for Plane Stupid said: “We know that the aviation industry’s emissions are killing us.
“Heathrow consistently breaches EU limits on Nitrous Oxides, causing poor health and early death.
“Within 20 miles of Heathrow Airport, aircraft emissions result in approximately 31 deaths per year. This January alone, London breached EU air pollution limits for the whole year in just eight days.
One of Plane Stupid's aims is to end to short haul flights and airport expansion.
The spokesperson continued: “This report helps to highlight the gravity of this invisible threat to all our lives.
“These figures provide more evidence that it is the government and the aviation industry, complicit in the poisoning of our air that should be on trial.
“They cannot be relied upon to take action on climate change or local air pollution, placing the interests of corporate profit over life here and around the world."
Air pollution local to Heathrow 'arises primarily from road traffic'
But Heathrow Airport insist they take air pollution very seriously and are taking action.
A spokesperson for the airport said: “We have already reduced annual emissions from airport activity by 16% over five years.
“But local air pollution arises primarily from road traffic, the vast majority of which is not related to the airport, and not airport emissions.
“Traffic pollution in London and on the major roads around Heathrow such as the M4 and M25 needs action from multiple partners.
“That is why Heathrow has called for coordinated and meaningful action from government and City Hall for an integrated transport strategy to get cleaner vehicles onto major roads and motorways.”
Across the whole of England 24,807 deaths were attributable to air pollution in 2013 - 5.3% of the total number of adult deaths that year.
This is an increase compared to 2012 when 5.1% of deaths were attributable to air pollution however it is less than in 2010 when the figure was 5.6%.
Although the number of deaths attributable to air pollution has decreased overall since 2010, 15 areas of the country have seen an increase of which Lincolnshire had the biggest - up by 8.3%.
The City of London had the worst air pollution rating in England with 8.4% of deaths in the area attributable to pollution.
At the other end of the scale the Isles of Scilly have the cleanest air in the UK with 2.8% of deaths attributable to air pollution.
