Abstract
The advancement of technology relating to participate emissions is pointed out as a significant aspect of this nation’s air pollution control efforts. Important factors include the ability of particulates: to cause poor visibility, to constitute a health hazard, to act as transport vehicles for gaseous pollutants, and (for some) to be highly active both chemically and catalytically. Attention is drawn to fine particulates (those with diameters less than about 3 microns) as an object of special attention within the general problem area. Recent EPA evaluations have indicated the effectiveness, under proper conditions, of advanced precipitators for fine particulate control.
