Comment on "Acid Fog"

Abstract

The March issue carried a feature article on "acid fog" (1). Concern is based on pH measurements made on samples obtained with a centrifugal collector. The low pH levels sound very damaging, but no damage to materials or health has been established. This lack of effect might be expected since damage depends on amount of acid making contact as well as the degree of acidity as measured by pH. This follows because acid-damage actions consume acid and because buffers that neutralize acid are invariably present in some degree.
