Abstract
Ozon je sekundarni plin koji nastaje fotokemijskim procesima iz prirodnih ili antropogenih izvora.Troposferski ozon se smatra onečišćivačem i ima štetan učinak na ljudsko zdravlje i okoliš. Gradovi u Hrvatskoj razlikuju se u geografskom položaju, naseljenosti i emisiji prekursora pa tako i koncentracije ozona variraju. U radu su korišteni satni prosjeci koncentracija ozona mjerenih tijekom 2014. i 2015. godine. Na svim promatranim mjernim postajama koncentracija ozona značajno pozitivno korelira s temperaturom zraka. Atmosferski tlak, vidljivost te smjer i brzina vjetra manje pridonose pojavi ozona, osim na mjernoj postaji Zagreb gdje vidljivost gotovo jednako pridonosi pojavi ozona kao i temperatura zraka. Koncentracija ozona negativno korelira s relativnom vlagom zraka u svim mjernim postajama. U polarnim dijagramima mjerne postaje Dubrovnik može se uočiti kako je koncentracija ozona povezana sa sjevernim, sjeveroistočnim i istočnim smjerom vjetra. U području grada Zagreba nema značajnog smjera vjetra, jer ozon nastaje na području same mjerne postaje, a tako isto je i u području grada Osijeka. U metodičkom dijelu diplomskog rada obrađena je nastavna jedinica Ozon i ozonski omotač. Obradom nastavne jedinice za 3. razred gimnazije učenici su naučili što je ozon i svojstva ozona te kako nastaje i na koji način naši postupci uništavaju ozonski omotač.

Parallel abstract (English)
Ozone is a secondary gas formed by photochemical reaction from natural or anthropogenic sources.Tropospheric ozone is considered as pollutant and could be harmful to the health of humans, animals or theenvironment. Concentration of ozone varies in Croatian cities due to difference in geographic location,demography and emission of precursors. Hourly averages of ozone concentration measured during the periodof 2014 and 2015 were used in the study. Concentration of ozone significantly correlated with airtemperature in a positive way at all observed stations. Atmospheric pressure, visibility, direction and speed ofwind have less impact on ozone occurrence. The concentration of ozone has shown a negative correlationwith air humidity at all observed points. Polar diagrams obtained at station in Dubrovnik have shown that theincident of ozone is related with north, north-east and east wind. In the area of Zagreb and Osijek, directionof wind is not notable since the ozone is produced in the zone of measuring point.In addition, the thesis contributes to teacher methodologie showing how a lesson like. Ozone and ozonelayer could be thought in a high school. Chemistry of ozone, its features, genesis, impact to the environmentand human influence to ozone layer has been presented. Teacher preparation including appropriatestoichiometric calculations and class experiments has been appended.
