[Polycyclic aromatic hydrocarbons in the beans, peas and broad beans from domestic market, 1999-2002].
Seeds of bean, peas and broad bean, purchased from local seed production plants in the provinces of Mazowieckie and Kujawsko-Pomorskie in the years 1999-2002, were determined for the contents of fifteen polycyclic aromatic hydrocarbons. The hydrocarbons were extracted from the seeds with a hexane-acetone mixture by means of sonification. The obtained extracts were then purified in a silica gel column. Polycyclic aromatic hydrocarbons (PAH) were identified and determined quantitatively with liquid chromatography using a fluorescent detector. The presence (in different concentrations) of PAH was reported in the majority of seeds of the bean, peas and broad bean varieties examined, which indicates that they may be ingested with food and bioaccumulated in the human organism. A considerably higher content of SPAH was observed in the seeds of broad bean, compared to those of bean and peas. The highest SPAH determined reached 2 x 10(2) microg/kg of product. The obtained results were comparable with those reported by other authors for vegetables originating from non-industrial areas. It is worth emphasising that all the seeds examined revealed the presence of PAH with carcinogenic properties.
