title: [Benzo(a)pyrene contamination of vegetable oils].
abstract: Benzo(a)pyrene (B(a)P) analysis was carried out with glass chromatographic column with alumina followed by reverse phase high-performance liquid chromatography (HPLC) and spectrofluorometric detection. B(a)P level in 40 vegetable oils were as follow: from 0.11 to 0.38 microg/kg in olive; from 0.92 to 3.74 microg/kg in rape seed oils; from 0.11 to 2.25 microg/kg in sunflower oils and from 0.33 to 1.26 microg/kg in soya oils. In another investigated oils: arachide (peanut) corn, safflower, linen, hempen, sesame, pumpkin seeds, grape seeds---values from 0.10 to 1.44 microg/kg and 3.83 microg/kg in sea buckthorn oil were detected. B(a)P concentration in 4 from 40 investigated oils exceed the 2 ppb limit proposed by the European Commission. Heating of sample of oils: olive, rape, soya, linen, corn, sesame, peanut, in temp. 240 degrees C for 30 min. has not influence on decreased of B(a)P level.
