Abstract


The challenging problem of climatic changes became an important reference point for various and numerousanalyses fighting against this threat. In Romania, few studies concerning the climate changes evolution are conducted,and urban pollution due to greenhouse gases emissions, is not enough studied. Testing the interrelations between aclimatic change indicator N2O and health status of three species of ornamental trees, Aesculus hippocastanum, Pinusnigra, and Tilia cordata, respectively, in Cluj-Napoca town, was the aim of our research.  The experimental model wasrepresented by the following tree species: Aesculus hippocastanum, Pinus nigra, Tilia cordata. Tree leaves status wasweekly recorded in 2014, and climatic data were delivered by the National Agency of Environmental Protection ClujNapoca.DatawereprocessedwithIBMSPSSStatistics20forWindows.Resultsemphasizes,ononehandthatthemost
