A solid dust particle won't actually be seen on the image but will affect image quality (and bokeh)
Dust particles won't affect bokeh. The bokeh effect here is from echos of that ring of available light which is quite a large thing.

What about haze? Can haze be thought of as an infinite collection of somewhat translucent dust particles?
Think of translucent as worse than a solid object. A solid object aborbs the light while a translucent object sends the light off into random directions lowering contrast. Think haze think bad.
