THE GUARDIAN:DOES LONDON HAVE THE WORST NO2 POLLUTION ON EARTH?

above article written by Mr. Karl Mathiesen produced  my below comment:

I am very sorry reading about above N02 pollution in Oxford Street, for I do believe it was measured there like that, but it does not mean that the other streets and parts of town are clean of it.
If I say that nitrogen dioxide reacts with humidity in the air following path:
NO2 +H2O = H2NO3
giving one of the strongest inorganic acid, I said all what people have to know!
For by inhaling 1 cubic meter of the air there,should I put poison instead the air ?,the people there are inhaling actually 135 micrograms of pure nitrogen acid that severely damages human lungs irreversibly.
If the NO2 did not reacted with the humidity of the air building nitrogen acid, there is still time to do so in the lungs of the people, for lungs are wet media...
Having in mind the capacity of the people's lungs that are several liters, from 2,5 l-4 l, and one liter is 1 decimeter cubic space, you can easily calculate the exposure to that deadly poison, having in mind how long you have walked in there.
Mothers, do avoid walking around with your babies!
And be alerted that safe limit of NO2 in the air is as the safe radioactivity in the environment, it says ZERO!
For very low content in the air, of NO2 in the adults can produce damages that are, I repeat irreversible, for the alveolus that are exposed to breaching no magic stick can recreate them again.
The horror scenario in the tiny baby lungs I do not want even to think about.
So keep in mind that the long exposure to this poison even at the low level can still produce huge damages, not mentioning short exposure to the high levels.
Once entered to the lungs, poison or crude particles of the air stays there, only small amount is possible to remove by coughing...
The each injury of lung tissue can be trigger for the cancer, emphysema...
So, this is the link between the lung diseases and pollution, that is marching on to the topic position of the lethal diseases in the EACH COUNTRY OF THE GLOBE...
Please keep in mind that the diesel engines are NOT ONLY TO BE BLAMED FOR, the refineries donate a great deal of nitrogen compounds into the air but fossil fuels combustion too, not mentioning the extreme situation such as the volcano eruptions but they are possible too.


UPDATE  July 11th 2014:
IARC= International Agency for Research Cancer has put Outdoor Air Pollution into first group of CARCINOGENIC , by its volume 109, the work is still in preparation.
