PESTAB. A method is described for the extraction and gas-chromatographic determination of pesticide residues in aromatic and medicinal plants, and results are presented of pesticide analysis in 42 samples from Algeria, Belgium, Egypt, Spain, Central Europe, France, Lebanon, Morocco, Turkey, and Yugoslavia. The samples were those of alburnum, basil, heather, fennel, juniper berries, anise, basil, bay leaves, lavender, mallow, yarrow, orange peel, marjoram, rosemary, savory, sage, thyme, serpolet, lime blossom, rose, and verbena. The average BHC content was 0.0001 mg/kg, and 2.38% of all samples were contaminated. The corresponding figures are 0.036 mg/kg and 100% for alpha-BHC, 0.028 mg/kg and 92.85% for lindane, 0.002 mg/kg and 4.76% for aldrin, 0.028 mg/kg and 40.47% for o,p'-DDE + p,p'-DDE, 0.008 mg/kg and 19% for DDD, 0.178 mg/kg and 76.19% for o,p'-DDT + p,p'-DDT, 0.004 mg/kg and 4.76% for dieldrin, 0.017 mg/kg and 2.38% for dicofol, 0.006 mg/kg and 9.52% for parathion, 0.006 mg/kg and 4.76% for diethion, 0.014 mg/kg and 2.38% for phosalone, 0.033 mg/kg and 2.38% for methidathion, and 0.133 mg/kg and 4.76% for sulfur.
