Temporal Assessment of Crop Protection Agents in Water Bodies of Haryana Districts

Abstract

Background: The study was conducted to quantify the presence of crop protection agents in 233 water samples collected from water bodies situated in cities of Panipat, Karnal, Rohtak, Sonipat and Hisar districts of Haryana, India. Water samples were collected during different seasons the year for the period from 2014-2018. Methods: The samples were processed by liquid- liquid partitioning method and quantified by Gas Chromatography and Mass Spectrometry. The water samples were screened for 55 pesticides. Result: Estimation of the residues revealed that 23.5 and 6.6% of pesticides were detected in 68 and 165 monsoon and winter samples, respectively. Chlorpyrifos, pretilachlor, butachlor and lambda cyhalothrin were predominantly present in all the water samples analyzed. Chorpyrifos detected in water samples from Karnal were above standard limit prescribed by EPA 8081and8141 but some samples were below UAS Health advisory life time value.
