AIR POLLUTION FROM KOSOVA POWER PLANT INDUCED CHANGES IN THE PHOTOSYNTHETIC PIGMENTS OF SOME PLANT SPECIES

Study was carried out to assess the impact of power plant pollutions on some plant species grown near in this area. In this paper, content of photosynthetic pigments (Chlorophyll and carotenoids) induced by air pollutants in Plantago lanceolata L., Trifolium pratense L., Dactylis glomerata L., Rumex crispus L. and Convolvulus arvensis L. leaves were followed. The experiment was conducted three times for the three months (May, June and July) at three localities in southern direction from power plant “Kosova A” and compared with samples from control areas. The highest reduction in total chlorophyll was observed in Dactylis glomerata L. (42.42%) whereas, the lowest reduction (19%) was recorded in Convolvulus arvensis L.. Similarly in case of carotenoid contents, highest reduction was observed in Dactylis glomerata L. (46.99%) and Rumex crispus L. (41.39%) and lowest in Plantago lanceolata L. (23.53%) and Convolvulus arvensis L. (19.67%). The reduction in total chlorophyll and carotenoid for the Trifolium pratense L. was observed about 30% for all parameters. The data obtained were further analyzed using one-way ANOVA and a significant change was recorded in the studied parameters. These studies clearly indicate that the power plant induced air pollution reduces the concentration of photosynthetic pigments in the many plant species exposed to the power plant pollution.
