Exercise increases the amount of lung exposure to particulate matter per unit time. Biking is also a slower mode of transit which increases risks, further cars have built in air filters which further reduce risks.

So it's really not equivalent. On the upside, bike paths need not be next to traffic and in those cases may reduce exposure.

I do not disagree with the dangers of air pollution it's just that if you look at large populations of bicyclists there are no significant elevation of risk compared to other populations in this regard.

The solution is not to scare people with baseless arguments.
