    During the EU project BEEP a battery of biomarkers was applied in flounder (Platichthys flesus) and the blue mussel (Mytilus edulis) collected at three locations off the Lithuanian coast (Baltic Sea) in June and September 2001 and 2002. The elevated biomarker responses in specimens sampled in September 2001 were apparently related to the extensive dredging activities in the Klaipeda port area and subsequent dumping of contaminated sediments. High concentrations of organic pollutants (organochlorines and PBDEs) were also measured in the tissues of both indicator species. In addition, response levels of genotoxicity, cytotoxicity, immunotoxicity as well as concentrations of PAH metabolites in the bile of flounder showed elevations in 2002 after an oil spill in the Būtinge oil terminal in November 2001. In flounder, biomarker measurements 10 months after the spill indicated recovery processes but in mussels a high level of genotoxicity could still be observed 22 months later. The present study illustrates the usefulness of the multi-biomarker approach in the detection of biological effects of pollution in this region of the Baltic Sea.

    Educators should attempt to create a common and solid strategy in preschool educational institutions in order to sufficiently ensure a safe social environment of children. A research examining health and safety issues in Lithuanian preschools was carried out in Klaipeda. The aim of this paper was to analyse the conditions of safe environment…

  3. The influence of the environmental management system on the environmental impact of seaport companies during an economic crisis: Lithuanian case study.


    Anne, Olga; Burskyte, Vilma; Stasiskiene, Zaneta; Balciunas, Arunas


    Freight handling in EU ports fell by more than 12 % during the global economic crisis in 2008-2009 after almost a decade of continuous growth. The decrease of freight handling in the Klaipeda seaport, the only port in Lithuania, was 6.7 % and happened due to the dominant outward movement of goods (mainly oil products). The Klaipeda seaport, due to its peculiarity, is the only ice-free port in the northern part of Baltic Sea. The present study explores the environmental impact of Klaipeda seaport activities from 2001 to 2011. Moreover, it compares the environmental effectiveness of environmental protection strategies used in the four biggest companies that, in fact, cover about 88 % of total activities (except general cargo) of the seaport. The first group of targeted companies used an environmental protection strategy to implement an ISO 14001-based environmental management system, and the second group selected to follow environmental management practices without certification. The paper analyses the development of the companies' activities in regard to the change of environmental effectiveness. The paper evaluates the pressure of the economic crisis on the companies' activities and its influence on environmental decisions, with particular interest in the ability of different environmental protection systems to resist and handle the expected performance. The study identified a significant decrease in companies' activities during the crisis period. However, the economic activities and environmental effectiveness demonstrated similar short-term tendencies in regard to the environmental strategy selection but differed in long-term perspective.

    Spores of the genus Alternaria belong to one of the most prevailing constituents of the air in all regions of the world. They form infectious inoculum of numerous plant species as well as severe inhaled allergies. The aim of this study was to compare the biological pollution with Alternaria spores of the air of 12 cities located in central and eastern Europe. The experiment was done in 2010 and it covered the territory of Latvia (LV), Lithuania (LT), Poland (PL) and Ukraine (UA). The spores were counted using an identical method and standard equipment (7-day Lanzoni volumetric sampler) followed by extensive statistical calculations. The timing of the day of maximum concentration changed mainly along the N-S direction and had a positive correlation with latitude. The most important factor determining the increase in Alternaria spore concentration was the temperature, whereas other weather parameters were not related or of low significance. Regardless of geographical location, the first phase of the season (0-0.9 % of Alternaria spores in the air) was the longest (up to 60 days) and the last (97.5 to 99 %) was the shortest (22 days or less). The means of daily concentrations of Alternaria spores ranged from 11 spores m(-3) in Klaipeda (LT, Baltic Sea coast) to 187 in Poznan (west PL, agricultural plain). The threshold value of 80 spores m(-3) that triggers the first allergy symptoms was exceeded in 8 to 86 days (Vinnitsa, UA, temperate continental, forest-steppes region). There were considerable differences between the highest number of spores per cubic metre of air, varying from 139 in the north (Klaipeda, LT) to 2,295 in central west (Poznan, PL). The biological pollution by Alternaria spores in several places of central and eastern Europe was high; the number of days exceeding the threshold value of 300 spores m(-3) connected with serious health problems of atopic people ranged from 0 to 1 on the north (LV, LT) to 29 in central west (Poznan, PL).

  5. Aquatic oil spill cleanup using natural sorbents.


    Paulauskienė, Tatjana; Jucikė, Indrė


    One of the most popular transportation methods of crude oil is water transport, leading to potential spills of these pollutants in the seas and oceans and water areas of ports, during their extraction, transportation, transhipment and use. The growth of the Lithuanian economy and the expansion of competitiveness were hardly imagined without the development of the Klaipeda seaport. However, the intensity of shipping and the increase in cargo loading volumes at specialised terminals are associated with a higher risk of environmental pollution. To achieve a sustainable development of the seaport, it is necessary not only to ensure the prevention of potential water pollution but also, if necessary, to use environmentally friendly technology for pollution management. The work analyses the possibilities related to the collection of oil products from the water surface using natural sorbents (peat, wool, moss and straw) and their composites.The research of absorbed amount of crude oil and diesel fuel spilled on the water surface, while using sorbents and their composites, determined that sorbents' composite straw-peat (composition percentage of straw-peat 25-75 %) absorbs the major amount of both crude oil (60 % of the spilled volume) and diesel fuel (69 % of the spilled volume) comparing to single sorbents and sorbents' composite straw-peat (composition percentage of straw-peat 50-50 %).

    Lang, Thomas; Wosniok, Werner; Barsiene, Janina; Broeg, Katja; Kopecka, Justyna; Parkkonen, Jari


    Results are presented of a study on liver histopathology in Baltic flounder (Platichthys flesus) carried out in 2001 and 2002 in four coastal sampling areas of the Baltic Sea: Kvädöfjärden (Swedish east coast, reference area), Klaipeda-Butinge (Lithuanian coast), Gulf of Gdansk (Polish coast), and Wismar Bay (German coast) within the framework of the EU-funded BEEP project. Liver lesions were diagnosed and categorised using standardised methodologies and, for a spatial and temporal assessment of the prevalence and types of lesions detected, a scoring system was applied, involving the calculation of mean histopathology lesion scores. 83.0% of the 436 female flounder examined (size range: 20-43 cm total length, age range: 2-8 years) were affected by liver lesions, out of which 74.3% were assigned to the category of non-specific, 3.4% to the category of early toxicopathic non-neoplastic, 4.6% to the category of pre-neoplastic and 0.7% to the category of neoplastic lesions. Mean lesions scores were highest in the areas at the Lithuanian and Swedish coast and there is indication of an impact of the age structure of the flounder populations studied, the sampling season as well as of contaminant effects.

    Activities of (137)Cs, (241)Am and (239,240)Pu were analyzed with special emphasis on better understanding of radionuclide transport from land via the Neman River estuaries to the Baltic Sea and behavior in the marine environment. Although activity concentrations of (137)Cs in water samples collected the Baltic Sea were almost 100 times higher as compared to the Curonian Lagoon, its activities in the bottom sediments were found to be comparable. Activity (238)Pu/(239,240)Pu and atom (240)Pu/(239)Pu ratios indicated a different contribution of the Chernobyl-originated Pu to the suspended particulate matter (SPM) and bottom sediments. The largest amount of the Chernobyl-derived Pu was found in the smallest suspended matter particles of 0.2-1 μm in size collected in the Klaipeda Strait in 2011-2012. The decrease of characteristic activity (238)Pu/(239,240)Pu and atom (240)Pu/(239)Pu ratios towards the global fallout ones in surface soil and the corresponding increase of plutonium (Pu) ratios in the suspended particulate matter and bottom sediments have indicated that the Chernobyl-derived Pu, primarily deposited on the soil surface, was washed out and transported to the Baltic Sea. Behavior of (241)Am was found to be similar to that of Pu isotopes.

  8. [Relations between usage of marihuana and other drugs among teenagers].


    Jurgaitiene, Dalia; Targamadze, Vilija


    Some supporters of liberal drug politics in the whole world and in Lithuania try to suggest that usage of marihuana and other cannabis products is harmless and marihuana can even be used for medical purposes. They state that usage of cannabis products does not lead to usage of stronger drugs and so on. Other authors state that regular marihuana use always leads to trying stronger drugs and development of drug addiction. The aim of this study is to examine connection between regular marihuana use and other drugs, to find factors that motivate marihuana users to try other drugs, and to name differences of attitude towards drugs and drug addiction between regular and irregular marihuana users. The research was conducted in six vocational schools of Klaipeda; 912 freshman students (mean age 17.5 years) were surveyed. During the survey, anonymous questionnaires were administered, and data were processed using SPSS program package. During the study, it was established that 15.6% of vocational schools' males and 4.9% of females smoked marihuana often or more often (more than 20 times). Those students are regular marihuana users, and they already may need medical or psychological help. Behavior and attitude of regular marihuana towards drugs users, which can be named as tolerance towards all drug usage ideology, statistically significantly differed from ideology of irregular marihuana users. The following percentage of regular marihuana users have also tried other illegal drugs: 58.6% have tried psychostimulants in the form of pills or powder (amphetamine, ecstasy, LSD, and others), 20.0% have tried intravenous drugs, 19.2%--various other drugs, and 42.4%--alcohol with pills.

    Oil products continue to be used as a principal source of energy. Wide-scale production, transport, global use and disposal of petroleum have made them major contaminants in prevalence and quantity in the environment. In accidental spills, actions are taken to remove or remediate or recover the contaminants immediately, especially if they occur in environmentally sensitive areas, for example, in coastal zones. Traditional methods to cope with oil spills are confined to physical containment. Biological methods can have an advantage over the physical-chemical treatment regimes in removing spills in situ as they offer biodegradation of oil fractions by the micro-organisms. Recently, biological methods have been known to play a significant role in bioremediation of oil-polluted coastal areas. Such systems are likely to be of significance in the effective management of sensitive coastal ecosystems chronically subjected to oil spillage. For this reason the aim of this paper is to present an impact of Mn, Cu, Co and Mo quantities on oil biodegradation effectiveness in coastal soil and to determine the relationship between metal concentrations and degradation of two oil products (black oil and diesel fuel). Soil was collected in the Baltic Sea coastal zone oil products degradation area (Klaipeda, Lithuania). The experiment consisted of two parts: study on the influence of micro-elements on the oil product biodegradation process; and analysis of the influence of metal concentration on the number of HDMs. The analysis performed and results obtained address the following areas: impact of metal on a population of hydrocarbon degrading micro-organisms, impact of metals on residual concentrations of oil products, influence of metals on the growth of micro-organisms, inter-relation of metal concentrations with degradation rates. Statistical analysis was made using ;Statgraphics plus' software. The influence of metals on the growth of micro-organisms, the biodegradation process
