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...

Particulate matters – affected air pollution and air pollution sources in the Northern part of Klaipeda are being analysed in the final work. The first part of the work focuses on the air pollution in Lithuania and worldwide, leteron methods and devices for measuring the concentration of the particulate matters in the air are being analysed. Earlier research works on this subject are being analysed together with various information sources. With the help of modern efficient air polution measurement devices, particulate matters – affected air pollution and air pollution causes in the Northern part of Klaipeda were examined. After collecting data on transport concentration in certain streets of the seaport, it was possible to do the modelling of segments of these streets. the resuls of the modelling are being compared with the results of the pre-existing research. The conclusions and recommendations of the final work are based on the analyses of the particulate matters – affected air pollution and itas spread in Klaipeda. the work consists of 8 parts; the Introduction, the Literature overview, the analyses of the air pollution estimation methods and devices, Particulate matters – affected air pollution analyses in Klaipeda city, the modelling of the particulate matters spread in the seaport, Conclusions, Suggestions and References. The volume of work is 119 p., excluding appendices, 56 illustrations, 17 Figures, 58 reference sources. Articles for publication and publications... [to full text]
