✦ Synopsis

In order to estimate the influence of NH3 on a forest in a clean atmosphere, the quality of the atmosphere in Sumava, South-Bohemia, was determined in September-October 1988. In this period the NOx, SO2, and aerosol concentrations were extremely low. The N-input into the forest margin amounted to 10-15 kg ha -1 in these two months, based on a deposition velocity of 3 cm s -~ and an average concentration of 9 ~g m -3 NH 3. The maximum hourly average ozone concentrations were found to be 50 to 100 p,g m -3. There exists a strong relation between the ambient NH 3 concentration profiles and the stable occupation. The concentration inside the stables exceeded the no-adverse-effect level for cows of 7.6 mg m 3.

This publication forms the basis for the estimation of the exposure of the forest to NH 3 and the interpretation of the observed effects as published elsewhere (Mejsffik et al.o unpublished).
