Abstract

Research on the effect of air pollutants on plants employs both laboratory and field experimental facilities. The advantage in using field-based facilities is the closer correlation of experiments with the natural environment. For field facilities, two distinct types of approach have been taken; (i) exclusion of ambient air in the experimental area and its replacement with air of the desired pollutant concentration using forced air delivery and various enclosing structures (Open Top Chambers, Air Exclusion Systems), and (ii) enrichment of ambient air with the pollutant gas and using ambient wind for dispersion (Free Air Carbon Dioxide Enrichment, Zonal Air Pollutant System). The objective of the work reported here is to
