W ziarnach zbóż jęczmienia i pszenicy uprawianych w bezpośrednim sąsiedztwie drogi krajowej nr 51 oznaczono stężenie sumy 16 WW A oraz wielkość pozostałości DDT, jego metabolitów i lindanu. Pozostałości ƩWWA wynosiły ok. 12-14 µg/kg ziarna badanych zbóż, w tym 0,2-0,6 µg/kg benzo(a)pirenu. Poziomy insektycydów chloro-organicznych w ziarnie zbóż oraz glebie były niskie, często poniżej granicy wykrywalności metody.

Total concentrations of 16 PAHs (as recommended by EPA) were determined in grain of wheat and barley cultivated near the Road no 51. Residues of y-HCH, DDT, DDE and DDD in the grain and soil collected at the place of grain sampling were also determined. The concentration of the 16 PAHs was low and averaged about 12 µg/kg. Concentration of benzo(a)pyrene in the barley grain (0.57 µg/kg) was significantly higher than that in the wheat grain (0.33 µg/kg). No dependence between PAH residues and the distance to the road was found. Residues of organochloride insecticides in grain and soil samples were very low, often below the detection limit of the employed analytical methods.
