W dostępnych na rynku polskim w latach 1999-2002 nasionach fasoli, grochu, łubinu i wyki oznaczono zawartość chlorowanych węglowodorów oraz polichlorowanych bifenylu Związki identyfikowano i oznaczano ilościowo metodą chromatografii gazowej. Pozostałości chlorowanych węglowodorów i polichlorowanych bifenyli odnotowano w większości badanych próbek na poziomie nie przekraczającym obowiązujących norm.

The contents of chlorinated hydrocarbons and polychlorinated biphenyls were determined in the seeds of selected varieties of bean, pea, lupine and vetch available on the home market in 1999-2002. The compounds were identified and quantified by gas chromatography.The concetrations of the chlorinated hydrocarbons and polychlorinated biphenyls detected in the majority of the analysed samples were within relevant standards. The contents of chlorinated hydrocarbons (y-HCH, DDT and its metabolites) and polychlorinated biphenyls (congeners 28, 52, 101,118,138,153 and 180) were determined in the seeds of selected varieties of bean, pea, broad bean, faba bean, lupine and vetch available on the home market in 1999-2002. To identify and quantify the compounds, plant material was extracted with cyclohexane. The resultant extracts were purified in a column filled with aluminium oxide and analysed in a gas Chromatograph equipped with a selective electron capture detector. Chlorinated hydrocarbons and polychlorinated biphenyls were identified in the majority of the seed samples, while their concetrations were well within relevant standards. Thus, contamination of legume seed with study compounds during the agricultural production processes is negligible.
