Technical Bulletin No. 0560: Application of Previous Air Pollution Exposure Techniques to Branch Exposure Chamber Design

NCASI is supporting research which will help to extend our understanding of how mature trees and forest stands respond to air pollution in comparison to seedlings. One of these efforts is a project at the Lawrence Livermore National Laboratory (LLNL) which is developing a Branch Exposure Chamber (BEC) to study the effects of air pollutants on western conifers. This is a cooperative effort, supported by the western Conifers Research Cooperative and NCASI. This technical bulletin provides a review of previous controlled exposure techniques used in plant/air pollution research.
