- •
We study canopy stomatal uptake of NOX, SO2 and O3 based on sap flow measurement.
- •
The GC value was regulated by the cooperation of the PAR and VPD.
- •
These studied trace gases had not yet reached injury levels, except for NO2.
- •
Flux-based measurement was better suited to evaluate risk than exposure-based method.
