One estimates amount of particles but the microscope you can, in some cases, determine what percentage of the particles you are looking at are from what source.  Or at least get an idea. and also estimate size with the right slide. For asbestos it needed a length to width ratio to be called a fiber and above a certain length. Not sure if there are requirements for smoke particles but I believe using this procedure one could come up with one.
