Abstract

The method and technology of the photoacoustic gas analysis enables highly sensitive investigations of CO₂ gas exchange different biosystems. The CO₂ evolution by some plants exposed to elevated concentration of pollutants and CO₂ emissen from the wood of tree rings at low air pressure is studied. All measurements have been performed using the photoacoustic gas analyzer with the tunable CW CO₂-laser.
