So the cyclists exercised for 2.8 times as long on average as the pedestrians and had 2.3 times the black carbon in their lungs.

In summary: cycling increases some health risks, and reduces other ones. The overall balance is that cycling has a positive health impact.
So let's not worry too much...

I believe a similar study of London tradesmen found the same thing. You ask them how much for a new boiler and then they suck a load of air through their teeth before they explain the price to you.

Well, I for one know that I'm going to die. I think the same is true for the rest of the population although they may not know it after all not long ago there was a medicinal product marketed on the basis that if you used it you had 30% less chance of dying.

I can cope with the black soot, to be honest. But I got stuck behind a bin lorry for ten minutes this morning and nearly threw up.

Yeah - that's really bad! Part of my route used to be near the Russell Road depot in Edinburgh, meaning I often got stuck cycling along behind bin lorries. The rank fumes coming out of them were so thick you had to chew the air before the particles were small enough to breathe in!

So the Daily Mail was right – cycling is very dangerous for your health and you are much better off enclosing yourself in a box, filtering out some of the particles (but not the really small, really dangerous ones) while generating loads more particles for the “plebs” outside…
My thoughts exactly. I recall reading somewhere (my apologies, don't have the reference) that sitting in a car breathing in the smaller particles is actually more deleterious to your long-term health.
The health risks and benefits of cycling in urban environments compared with car use: heath impact assessment study, Rojas-Rueda D, de Nazelle A, Tainio M, Nieuwenhuijsen MJ, BMJ 4 August 2011.
Results Compared with car users the estimated annual change in mortality of the Barcelona residents using Bicing (n=181 982) was 0.03 deaths from road traffic incidents and 0.13 deaths from air pollution. As a result of physical activity, 12.46 deaths were avoided (benefit:risk ratio 77). The annual number of deaths avoided was 12.28. As a result of journeys by Bicing, annual carbon dioxide emissions were reduced by an estimated 9 062 344 kg.

Er, what?
Bicing? What's that?
Mmmmmmm.........cake.........
Bicing is the Boris Bikes of Barcelona.
