Abstract
In this paper an attempt has been made for the impact studies of industrial pollutants on agricultural soil as well as Kabini river sediments of Nanjangud industrial area near Mysore, Karnataka. The present study is focused on the seasonal variation of the constituents of samples during pre-monsoon, monsoon and post-monsoon seasons of 2009-2010. Four agricultural soil samples and five sediment samples from river bed of Kabini river were collected. These samples were systematically analyzed for physico-chemical parameters and subjected to heavy metals analysis. The experimental results reveal that, during the pre-monsoon season, most of the samples show highest concentration of the contaminants compared to other seasons. Thus, pollutants concentration are fluctuating from season to season, which implies that, pollution load is increased due to industrialization and runoff from the agricultural fields. So, extensive addition of micronutrients would neither be economical nor safe from environmental points of view. However, proper remediation measures need to be taken for sustainability of the ecosystem.
