Abstract

The purpose of this study is to develop and validate a simple method suitable for analysis of trace amounts of endosulfan in cabbage. Cabbage samples were extracted with acetone and endosulfan was partitioned into dichloromethane/n-hexane (1:1, v/v). Final determination was performed by gas chromatography with mass spectrometry. Recovery studies were performed at 0.02 mg/kg fortification level of each compound (endosulfan I, endosulfan II, endosulfan sulfat) and the recoveries obtained ranged 69.67% to 124.02% with coefficient of variation values of 5.56-11.54%. The method showed good linearity over the range assayed 2-6 µg/mL and the detection and quantification limits for endosulfan studied varied, 0.1273 µg/mL to 0.1469 µg/mL and 0.856 µg/mL to 0.4451 µg/mL respectively.
