Abstract
It is supposed that air pollution is one of crucial factors in contamination of vegetable oils. The content of 3,4-benzpyrene was determined in nonrefined oil, obtained from sunflower seeds which were grown in areas with varying degree of pollution, and in the samples of soil taken from the same areas. Possible influences during the ripening of the seed (harvest, transport, storage) until the final industrial processing were excluded. Seed samples were hand collected and oil samples prepared under laboratory conditions. The amount of 3,4-benzpyrene in oil ranges from 0.4-40,5 µg/kg oil and shows direct relationship with the intensity of air pollution. A relatively high content of 3,4-benzpyrene in soil samples (29.3-900.0 µg/kg soil) points at a high resistance and possibility of accumulation of this carcinogenic substance.
