Abstract:
The determination of some selected organochlorine pesticide residues in some vegetables grown within Gwagwalada Area Council were carried out using Gas Chromatography-Mass Spectrometric Technique (GC/MS). Lindane, Dieldrin, Endosulfan, and Heptachlor were determined in Telfairia occidentalis, Amaranthus hybridus, and Talinum triangulare obtained from some locations within Gwgwalada Area Council between the months of May and June, 2015.
The pesticides were extracted by the method of EU CEN 15662 QuEchERS (quick, easy, cheap, rugged, and safe). Recovery studies of Lindane and Dieldrin were good ranging from 98.73 - 99.80% and 98.02 - 104.30% respectively. The range of the concentration of Lindane, Dieldrin, Endosulfan and Heptachlor in the samples varied from ND -0.091, ND - 0.133, ND - 0.0021, and ND -0.008µg/g respectively.
The levels obtained for the samples were generally lower than the recommended acceptable limits.
