It was established that that the essential impact on the leaves (the generation process of chlorophyll "a" of Tilia cordata it causes the conditions at CET-1, followed by Alecu Russo subsequently Moscow avenue and the diminished it is for the Botanic Gadin. Data analysis on the content of chlorophyll "a" chlorophyll "b" for Tilia cordata is 2.8 times higher chlorophyll "a" and 2.6 times for chlorophyll "b" compared with values for Pinus nigra chlorophylls. These results confirm that process of generating Tilia cordata chlorophyll species is larger than the species Pinus nigra. It was determined that the impact of vehicle emissions on the generation of chlorophyll "b" is unimportant for all stations. The data demonstrates that the greatest impact of vehicle emissions it causes the chlorophyll "a" and therefore as an indicator of the degree of pollution is required to receive the content of chlorophyll "a". It was determined that the impact of road transport emissions to be measured by the ratio value of chlorophyll "a" / "b" for each station. The more value ratio is lower by both the impact is essential, and conversely, higher value ratio corresponds a minimal impact. |
