Running can cause you to take in more of the pollutant because you’re spending about the same amount of time exposed to it but taking in way more air. Cycling may or may not cause you to take in more air depending on effort, but exposes you for less time so your overall exposure can be less. Cycling also operates as an alternative to the transport that produces the particles in the first place.
