Subject of research: different parts – roots, stems, leaves, berries – of bilberries (Vaccinium myrtillus L.), growing near the A1 Vilnius – Kaunas – Klaipėda highway (the 94th kilometre, right side of the road). Objective of research: to determine the amount of lead in different parts of bilberries. Methodology: for research the samples of bilberries were picked near the A1 Vilnius – Kaunas – Klaipėda highway at the 15 – 20 km distance from Kaunas, at 10, 15, 20, 25, 30, 35, 40 and 70 m distance from highway. For experiment – at 100 m distance from highway, bilberries were replanted in laboratory and were grown in the soils of different lead concentration four months. The soil was sprinkling with lead nitrate (Pb(NO3)2) solution of different concentration. The samples of plants were desiccate. The mineralization of different part the plants was carried out, as well as the analysis of soil was made (pH, ratio of hygroscope humidity, concentration of lead in soil). The amounts of lead in plants and soil were determined by the method of atomic absorption spectrometer. Research carried out in accordance with legally approved methodologies. For the statistical evaluation of differences the ANOVA and STATISTICA has been applied. Results of research: by carrying out the research, the amount of lead in different parts of the plants was determined; the dependence of lead amount in different parts of the plant upon the lead amount in solution was analysed; it was evaluated the...
