Open top chambers (OTC) have been used to study effects of air pollutants on plants for over 25 years. Many of those studies have used potted plants, producing environmental and ecological rooting conditions that are unrealistic. Others have placed OTC over existing vegetation, which increases experimental variability by using non-uniform soil conditions. We describe modifications that include the use of native soils and environmental controls to achieve experimental conditions that are more reproducible than field experiments but more realistic than traditional OTC experiments.
