| Abstract |
A continuous flow system for exposing plants to submicron aerosols of sulfuric acid has been developed and an operational model has been constructed. Exposure chambers have been designed to allow simultaneous exposures of the same plant to aerosol and control environments. All surfaces within the exposure system are composed of either Teflon or stainless steel to minimize corrosion. Submicron acid aerosols are mechanically generated and are distributed in size representative of resident particulates found in the atmosphere. Plants have been found to be injured by exposures to high concentrations of sulfuric acid aerosol (100-200 mg/cum) for short times of 4-16 hours. Injury to vegetation caused by sulfuric acid aerosol is similar to that caused by gaseous fluoride and is characterized by marginal and tip necrosis of foliage. Different plant species vary greatly in sensitivity to sulfuric acid aerosol and injury to sensitive species appears to be conditioned by biological as well as physical factors. |
