Levels of Aldrin and Endosulfan pesticide residues in green fodders of Varanasi district, Uttar Pradesh, India

Abstract

The present study was conducted to find out the organochlorine pesticide (OCP) aldrin and endosulfan residues in fodder samples in Varanasi District, Uttar Pradesh, India. Green fodder samples collected from the four block of Varanasi in which five villages selected evenly distributed from each block, were analyzed by gas chromatography-mass spectrometry (GC-MS) for OCP residues. Aldrin concentration (mg/kg) in green fodder obtained from different blocks were 0.00198 (Baragaon block), 0.00092 (Cholapur), 0.00133 (Araziline) and 0.00198 (Harhua). In Baragaon, Cholapur, Araziline and Harhua block 66.66%, 33.33%, 60% and 40 % samples, respectively were contaminated with endosulfan. The mean level of endosulfan concentration was found to be 0.00214 mg/kg throughout the year. In green fodder samples maximum concentration was found in winter (0.00296 mg/kg) and minimum was found in rainy with mean residues level of 0.00123 mg/kg.
