A study of Pesticide Residues in Water Samples of Agricultural Areas from H.D Kote Taluk, Mysore, Karnataka, India

Abstract

Pesticides are biologically active chemicals which are used for killing the pests. These substances are meant for attracting, seducing of plants or animals, causing harm during or otherwise interfering with the production, and then destroying or mitigating any pest. Water samples were collected from different cultivated agricultural fields of H.D.Kote taluk and physico-chemical characteristics were experimentally determined. The analysis of physico-chemical characteristics of water showed that, parameters like Total hardness, Electrical conductivity, Sulphate were within the permissible limits of WHO standards. The Dissolved oxygen was found to be higher than the permissible limits, which indicates reduction in load of biodegradable materials in water. The Alkalinity and Nitrite showed the higher concentration indicates. In water samples pesticides were analyzed through LCMS. LCMS analysis 5 of 7 water samples; some of the pesticides were detected. In the present study areas, farmers are much familiar with pesticides to protect and boost up their crops. As a result, pesticides were present in the water bodies, which were confirmed from LCMS study. So, farmers of this area have to give more attention on their daily usage of pesticides.
