Another piece of misinformation.
Although PM5 and PM10 particulates are inhaled, the body has a mechanism for expelling them.
The exhaust emission that is often not reported, as it might frighten some poor blighter to death, is NOx. NOx are the 'oxides of Nitrogen' molecules such as NO and NO2, Nitric oxide and Nitrogen Dioxide.

When NO2 combines with the humidity in your lungs, it forms acid rain. Unfortunately, your body doesn't expel it and it burns its way through the alvioli and drives the nervous system barmy.
The fatal dose is 50 parts per million.

14 Nitric oxide is a severe eye, skin and mucous membrane irritant. Nitrogen dioxide is a highly toxic, irritating gas. There has been some reports of exposure to high levels of nitrogen dioxide (as generated by oxy-fuel gas cutting in confined spaces) resulting in severe ill health and even death. Initial exposure to high concentrations of the gas can
however result in only mild irritation followed by a symptom free period of several hours. However, this can develop into a build up of fluid on the lungs which in severe cases can sometimes be fatal. Both nitrogen dioxide and nitric oxide have been shown to have mutagenic potential, which raises possible concerns for lung cancer.

Paper filters do not filter NO and NO2.
No need to worry folks.
I've been attending drag race meetings for thirty years and have gone home with many a 'Nitro hangover'.
I worked for many years in a Motor car exhaust gas analysis laboratory dealing with bottles of 50 and 100 ppm Nitric Oxide.
Thanks to the cycling, I have a higher than average lung efficiency, even at the age of fifty.

- ...I don't have much idea - really.
...but we now know why you're crackers jimbo! 
Aren't all these patrticulates inside vechiles anyway? I'm hoping that the effect of cycling will be greater than any additional exposure, and even if not cycling is so much more enjoyable than travelling in a vehicle.
The only benefit of vehicles for me is the distance/time ratio.

Exhaust fumes ain't the half of it. Get a lung full of this lot:

The samples were collected at 30cm above ground level, where as most monitoring is carried out at about 3m above ground level (to avoid vandalism, or to reduce the measurements so the local authorities don't have to go anything about it, if you want to cynical) and found that concentrations are higher, which is why they found it had more of an impact on children. It also explains why you get higher concentrations in cars as that is about the hight of their air intakes. So for most cyclist it is not a problem, unless you ride a bent...
