Paper 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.
