The authors discuss a program to provide a first step towards assessing acute health-related effects of acid fog exposure. Polluted ambient fog was simulated in a laboratory exposure chamber. Volunteer subjects were purposely exposed and studied during periods of exercise and rest while in the challenge atmosphere. Respiratory responses were measured by methods used to assess effects of irritant gases and dry'' respirable aerosols. When a pilot study showed no obvious unfavorable effects with ambient-like pollution conditions, the exposure concentrations for the present study were extended into the occupational range, well above ambient levels. Sulfuric acid was selected for use as the test pollutant, based upon previous research experience and the availability of fog data documenting its presence during ambient fog episodes.
