Description :
Increasing industrialization and anthropogenic activities is the main agent of pollutant discharge into the environment and introduce various harmful substances into the atmosphere. It is difficult to estimate the effects of air pollutants because the organisms are exposed to a wide range of uncontrolled variables (parasites, weather conditions, complex mixture of pollutants). On the morphological, anatomical and physiological point of view, the plants from polluted sites present important changes especially regarding their colors, shapes, leaf length, width, stomatal and trichome frequency and chlorophyll content. However, despite of these changes, plants were survived well at the polluted environment of Koradi and Khaperkheda. These results showed the importance of morphological data for precocious diagnosis injury and to determine the sensitivity of different plant species to the action of air pollutants. After this study, we can consider that there is still a serious lack of knowledge of the impact of air quality on vegetation in the industrial urban areas. Overall, the study reveals that all the plant species growing in the polluted environment of the thermal power plant are badly affected by emission. There is a need to set limits on how much of a pollutant is allowed in the air.
