“…In the present study, species diversity was significantly and negatively correlated with ambient SO2 concentrations during the rainy (r = -0.702; p < 0.01) and dry (r = -0.618; p < 0.05) seasons. In a study to assess the effects of coalfired thermal power plant emission on the vegetation of a mixed oak forest with white pine, Rosenberg et al (1979) found that the IVI of certain species and species diversity were inversely related to the distances from the source of emission. An obvious community simplification around an iron smelter near Wawa, Ontario has been reported (Gordon and Gorham, 1963).…”

“…It is well established that the stress from regionally transported acidic deposition and gaseous pollutants can cause structural and functional changes in plant communities (Lauenroth and Milchunas, 1984;Kozlowski, 1985), leading to subtle degradation of plant ecosystems (Rosenberg et al, 1979). Air pollutants can affect various levels of ecosystem organization, starting from an individual leaf to an entire ecosystem (McClenahen, 1978;McLaughlin, 1985).…”

Effect of power plant emissions on plant community structure

A field study was conducted around two coal-fired thermal power plants (TPP) to analyse the impact of their emission on the structure of herbaceous communities in a dry tropical area. Phytosociological studies reflected that Cassia tora, Cynodon dactylon and Dichanthium annulatum dominate at heavily polluted sites. Alsycarpus monilifer, Convolvulus pluricaulis, and Desmodium triflorum are uniformly distributed, whereas Paspalidium flavidum, Phyllanthus simplex, and Rungia repens are dominant at less polluted sites. On the basis of Importance Value Index, the species were classified as sensitive, intermediate and resistant to TPP emissions. Shannon-Wiener Index of species diversity, species richness and evenness were inversely related, whereas concentration of dominance was directly related to the pollution load in the area. Significant negative correlation between ambient SO2 concentration and species diversity suggested selective elimination of sensitive species from the heavily polluted sites.

“…Thus changes in the forest ecosystem were attributed to both the primary impact of air pollution and secondary effects arising from changes in competition. Rosenberg, Hutnik and Davis (1979) carried out a similar type of study in a mixed oak forest in central Pennsylvania, subjected for 25 years to an isolated source of S0 2 (and presumably NO x ) in the form of a coal-burning power plant. It was shown that the importance of Pinus strobus and Betula lenta increased with distance from the emission source, while that of Quercus alba and Acer rubrum decreased, these effects being more pronounced downwind than upwind of the power plant.…”

An atmospheric deposition study was conducted in the downwind of Shaktinagar Thermal Power Plant (STPP), Renusagar Thermal Power Plant (RTPP), and Anpara Thermal Power Plant (ATPP), at Singrauli region, Uttar Pradesh (UP), India to characterize dry and wet deposition in relation to different pollution loading. During the study period, dry and wet depositions and levels of gaseous pollutants (SO2 and NO2) were estimated across the sites. Dry deposition was collected on a monthly basis and wet deposition on an event basis. Depositions were analyzed for pH, nitrate (NO3-), ammonium (NH4+), and sulphate (SO4(2-)) contents. Dry deposition rate both collected as clearfall and throughfall varied between 0.15 to 2.28 and 0.33 to 3.48 g m(-2) day(-1), respectively, at control and maximally polluted sites. The pH of dry deposition varied from 5.81 to 6.89 during winter and 6.09 to 7.02 during summer across the sites. During the rainy season, the mean pH of clear wet deposition varied from 6.56 to 7.04 and throughfall varied from 6.81 to 7.22. The concentrations of NO2 and SO2 pollutants were highest during the winter season. Mean SO2 concentrations varied from 18 to 75 g m(-3) at control and differently polluted sites during the winter season. The variation in NO2 concentrations did not show a pattern similar to that of SO2. The highest NO2 concentration during the winter season was 50 g m(-3), observed near RTPP. NO2 concentration did not show much variation among different sites, suggesting that the sources of NO2 emission are evenly distributed along the sites. The concentrations of NH4+, NO3-, and SO4(2-) ions in dry deposition were found to be higher in summer as compared to the winter season. In dry deposition (clearfall) the concentrations of NH4+, NO3-, and SO4(2-) varied from 0.13 to 1.0, 0.81 to 1.95, and 0.82 to 3.27 mg l(-1), respectively, during winter. In wet deposition (clearfall), the above varied from 0.14 to 0.74, 0.81 to 1.82, and 0.67 to 2.70 mg l(-1), respectively. The study clearly showed that both dry and wet depositions varied between the sites and season, suggesting significant impact of industrial activities in modifying the atmospheric input. The nonacidic deposition suggests that there is no threat of acidification of the receiving ecosystem at present.
