A study was undertaken to identify the residue level in palm fruits and its products by spiking the fruits at 5 ppm with14C-[UL]-lindane and following up on the residue during simulated commercial processes. The study concluded that steam distillation (deodorization) is an effective process in removing lindane residues. Under experimental conditions, commercial processes removed some 74% of insecticide residues from crude palm oil. Based on the oil content (up to 50%) of the pulp the residue concentration in the refined oil may exceed 2.5% mg/kg. The result suggest that the refined oil may retain one quarter of lindane received by the fruit. 1 tab
