Impact of Anthropogenic Air Pollutants on Soil Nutrients in Bengaluru

Human activities pose an impact on the environment, which can be monitored by the mineral content in the soil. Four different locations based on specific environmental characteristics was selected for the study which included residential area, commercial area, an industrial area and a control site. Soil micro and macro nutrients have been investigated in the control and study sites in this study. All the nutrients were seen in low concentration in the control site, when compared to other study sites and their concentrations varied with the increasing depth. In this study, the highly polluted site (Industrial area) had the highest content of nutrients. The macro and microelement contents depend on the type of plant and its environment (the level of industrial development of the region, air pollution and soil and climate conditions) (Voutsa et al. , 1996, Ngole and Ekosse, 2009). Macro and micro elements released from anthropogenic sources that have entered the environment is the main focus of this study.
