Environmental health perspectives, 79, 121-126 (1989-02-01)
The ability of the lungs to clear deposited material is essential for maintenance of lung homeostasis. Acid aerosols have been shown to alter the efficiency of this process. This paper assesses the role of acid aerosol exposure concentration (C), exposure
