Abstract

Air pollution is the contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. The exhaust of industries, automobiles, household combustion and various devices cause air pollution. Oxides of nitrogen, sulphur, particulate emissions are a few of the examples as pollutants from industries. These air pollutants drastically affect photosynthetic pigments and reduce chlorophyll content of the plants growing in polluted sites. The reduction in chlorophyll is due to conversion of chlorophyll into pheophytin by loss of magnesium ions. In the present study, formulation of bio-fertilizer has been made using nitrogen fixing bacteria and phosphate solubilising bacteria and its effect has been studied under various parameters. Bio-fertilizers overcome the effects of air pollution on plants. It can enhance the chlorophyll content of Fenugreek and spinach. Effective bio-fertilizer has great potential to replace chemical fertilizers.
