PESTAB. A process for detecting residues of the insecticide toxaphene in honey is described. An extract of the honey is made with ethanol, acetone, sodium chloride, diethyl ether and n-hexane. The carrier solvent is a mixture of carbon tetrachloride: petroleum ether (60:40) and the developer is a silver nitrate solution. A minimum of 0.6 mug toxaphene is detectable optically, and 1 mug by semi-quantitative analysis. If DDT, DDE or HCH (BHC) are present, this procedure will need to be supplemented with ultraviolet spectroscopy or a more precise chromatography.
