Cumulative effects of agricultural crops exposition, forests and other ecosystems for ozone concentration above the threshold is characterized by exposition index AOT. According to experst for EHK, the recent level is 40 ppb. Very dry summer in 2006 and 2003 created good conditions for photochemical reaction as well as ozone transport in Central Europe. Such years can be taken as an example in connection with expected concentration of ground ozone (as a result of global warming). Amount of ozone in troposphere is measured in Botanic garden and MZLU arboretum areas since 2001 by analyzator 41M–LCD. Ozone course correlates with course of air temperature from end of May till end of August. Coefficient of correlation for 2006 was 0,872 and year 2003 was 0,777, which is statistically significant. Similar course was found for summer months of 2004 (0.703), a bit lower as 2006. There were exceeded imission limits for vegetation protection and AOT40 in 2003 and 2004. There were the highest values for vegetation protection in 2006, 2003 and 2004. Immision limits exceeded 90 days in 2006, 61 days in 2003 and 53 days in 2004.
