The annual average concentrations of SO{sub 2} around Obra thermal power plant and nonpolluted sites in India were reported as 0.06, and 0.007 ppm, respectively. However, daily average concentrations in areas close to the emission source may be as large as 0.34 ppm. Therefore, in the present investigation an attempt has been made to determine the potential effects of such episodic and exceptionally high intermittent concentrations of SO{sub 2} on total chlorophyll content and nitrogenase activity of Vicia faba (broad bean) plants.
