One of the papers which I've uploaded is quite relevant to L8-OLI and PM10 estimations. It should be helpful. The other paper is from the School of Physics, Universiti Sains Malaysia which might be closer to you. Although they have worked on Mapping Air Quality with Landsat TM I think the techniques can be quite similar. Try to get in touch with the researchers, I'm sure they would be pleased to help you. All the best!
