Ozone (O3) concentrations were monitored during summer seasons of 1997-1999 in forest of three mountain regions in the Czech Republic: Šumava, Brdy, Jizerské hory. These mountain ranges represent different level of environmental pollution. The ozone bioindicators were used to verify the effect of ozone on plants. For this purpose the plants of tobacco and clover were used. The plants were grown in clean-air greenhouse and then exposed for 2-3 weeks on sites together with passive samplers. The project results brought some new information about the appearance of ozone and its phytotoxicity. The project was co-ordinated with a similar studies in Slovakia, Poland, Ukraine and Romania. The final results are published in several articles in a special issue of Environmental Pollution journal.
