Hmm, the way I would do it, is with absorbing media applied to a cylinder
with a radius just a little bit smaller than the column's. Its density
might be (emi-)spherical so the vast majority of the grime would be located
near the bottom.

Nice pic, BTW. I really like the sky, it looks like a "simple" procedural
sky, but simple procedural skies are anything but simple to get right, IMO.
