Přízemní ozon a jeho vliv na vegetaci

Original language description

Tropospheric ozone (O3) is responsible for both human respiratory diseases and disturbance of vegetation due to damage of photosynthetic apparatus, which leads to reduced ability to absorb CO2 from atmosphere. The O3 concentration has increased from pre-industrial era level of 10-15 ppbv to current concentration of 35-40 ppbv. Its maxima are reaching up to hundreds of ppbv in peri-urban locations. Due to increase of O3 precursors, the concentration is increasing by 5 ppbv per decade at Northern hemisphere. Therefore, net ecosystem production of forest ecosystems is declined up to 30%. The aim of the presentation is to review results of manipulative experiments simulating influence of high O3 concentration and results from eddy covariance flux measurements performed at real conditions in forest. Interactive effects of other environmental conditions, such as radiation, relative air humidity, drought, air temperature and nitrogen deposition will be also presented. Experiments currently running at Czech-Slovakia border (Bílý Kříž, Beskydy Mountains), particularly eddy covariance measurements of O3 and other trace gas fluxes and measurements of within-canopy O3 concentration profiles, will be presented too.
