ASSESSMENT OF LINDANE (GAMMA HCH) RESIDUES IN WATER AND MILK SAMPLES IN PALAKKAD DISTRICT

Abstract

Organochlorine pesticides are ubiquitous and persistent organic pollutants used widely throughout the world. The organochlorines are more potent due to their prolonged persistence, lipophilic nature and tendency to accumulate in anima! and plant tissues. The present study was therefore undertaken to assess the level of Lindane residues in water bodies and milk samples from cattle of Pudussery and Perumatty panchayath of Palakkad district, Kerala. Total mean Lindane (Gamma HCH) levels in the water and milk samples (ppm) from study area were 1.935 x 10~~ ± 6.779 x 105 and 2.600 x 10'3 ± 7.734 x10-' respectively. The levels of Lindane residues (ppm) in water and milk samples were within the maximum residue limit as per FAO/ WHO recommendations.
