Emission Factors for Abrasive Materials
Abrasive blasting materials, such as coal slag garnet and copper slag, are often used for cleaning metal surfaces to remove rust and to prepare a surface before the appliion of a coating. The preblast and postblast (spent) abrasive materials contain traces of heavy metal constituents such as Cr, Mn, Ni, Pb Fe, and Ba. Hence, the health risk associated with the resultant particulate ...
