Arak, the national alcoholic drink in Lebanon, was prepared from grapes to which either DDT or parathion had been added. Samples of the nine fractions produced from the fermentation and distillation steps were analyzed for DDT and parathion and their respective metabolites. DDT degraded to DDD during the fermentation step resulting in a sharp decrease in DDT level. The two distillation steps contributed to a further decrease in the DDT level so that the final product contained less than 2% of the amount found in the fresh grape juice. Although the concentration of DDD increased sharply during fermentation, it also decreased to a negligible level during the subsequent distillation procedure. Parathion was more stable than DDT during the fermentation and first distillation steps. However, the second distillation process caused a sharp decline in its level and the Arak contained only about 6% of the residues present in the fresh juice, paranithophenol being the only metabolite detected.
阿拉克酒是黎巴嫩的国民酒精饮料，由添加了滴滴涕或对硫磷的葡萄酿造而成。对发酵和蒸馏步骤产生的九个馏分样本进行了滴滴涕、对硫磷及其各自代谢物的分析。在发酵步骤中，滴滴涕降解为滴滴滴，导致滴滴涕水平急剧下降。两步蒸馏使滴滴涕水平进一步降低，因此最终产品中滴滴涕的含量不到新鲜葡萄汁中含量的2%。尽管滴滴滴在发酵过程中浓度急剧增加，但在随后的蒸馏过程中也降至可忽略不计的水平。在发酵和第一次蒸馏步骤中，对硫磷比滴滴涕更稳定。然而，第二次蒸馏过程使其水平急剧下降，阿拉克酒中仅含有新鲜果汁中残留量的约6%，对硝基苯酚是唯一检测到的代谢物。
