Pesticides Persistence in Soil and Kabini River Water at Nanjangud Region

Abstract

Environmental contamination due to persistence of pesticide residues is gaining worldwide attention. Exposure to pesticide residues can represent a potential risk to any organisms. The residue level of pesticides were quantified in 16 samples during the year 2013, among those four for water, five for sediment samples from Kabini river, three for ground water and four for agricultural soil samples from the Nanjangud region of Southern India. Samples were extracted for pesticide preparation prior to analysis with Gas Chromatography. A total of 12 Organochlorine pesticides were examined. The experimental results revealed that, isomers of HCH, DDT and Heptachlor were detected in water and soil samples, whereas, β-isomer was detected in the sediment samples. Among the isomers of HCH, β- isomer was predominant in all the studied samples. Detection of pesticide residues shows serious threat to the ecosystem. Thus, water and soils in the vicinity of the industries need to be paid much attention
