:::::::It's not just one MEDRS source; there multiple sources saying the same thing: the accurate term is aerosol. And this is not merely a technical distinction: the ultrafine particles in the aerosol create health risks that would not be posed if the emissions were merely vapor. The argument that common parlance should be used has been been made in the past; but the argument that WP should use correct terms seems at least as compelling, particularly when the incorrect term is misleading.
