Abstrakty
Przeprowadzono analizę zawartości 16 podstawowych wielopierścieniowych węglowodorów aromatycznych (WWA) w olejach jadalnych. W części próbek stwierdzono przekroczenie zalecanych przez ustawodawstwo niemieckie norm zawartości WWA, tj. 25 µg/kg w przypadku sumy WWA oraz 5 µg/kg dla sumy WWA kancerogennych.
Polycyclic aromatic hydrocarbons (PAHs), are formed by the incomplete combustion of organic matter. They are widely distributed in the environment and human exposure to them is unavoidable. The ability to produce tumours in experimental animals has been shown in various PAHs and they are thought to be significant contributors to cancer development in humans. Their presence in the environment is reflected in their presence at detectable levels in many types of food. Fatty foods are particularly prone to PAHs contamination because of their strong lipophilic characteristic. Fats and oils represent one of major sources of PAHs in human diet. In this study, 25 sorts of edible oils available in retail shops in Szczecin were analysed. The following samples were analysed: soybean, rape, sunflower, maize, peanut, grapeseed and olive oils. The analytical method involved extraction by dimetylofor-namide/cykloheksane partitioning, cleaned up by florisil cartridge and analysis by GC - MS. BaP, the most carcinogenic PAH was detected in all samples, at levels 0,03 to 4,0 µg/kg (rape oil). Highest level of total 16 PAHs was found in olive oil 70,7 µg/kg.
