In 2003, the Japan International Cooperation Agency carried out a development feasibility study of Klaipeda Seaport (Lithuania). The focus in this study was the evaluation of environmental impacts of the port expansion because it is located in an ecologically sensitive area. While the Japanese researchers focused on the environmental impact analysis, they did not provide unambiguous conclusions. The problems remained unresolved and required further, more detailed consideration and deeper analysis. Environmental sustainability in seaports is an issue of timely importance in many countries given the rapid increase in port-to-port traffic and harbor capacity. This paper explores the situation in Klaipeda Seaport (Lithuania) which is the northernmost ice-free port on the Eastern coast of the Baltic Sea and its challenges in terms of environmental aspects and current pollution situation. This port plays an important role in the economic development of the region and in creating a sustainable society, i.e., a society that continues to develop economically without increasing its impact on our living environment and where the possible reduction of its current impact can be huge due to the fact that the seaport is a place where transport and logistics intersect and constitute large-scale industrial estates. Increasingly, they also turn towards sustainability. Society faces the need for radical change because of increasing technological progress and increasing environmental impact. Environmental and public issues must be addressed by a systemic approach to find harmony among all the subsystems. Therefore, the authors of the article performed an assessment of the deep-water port of Klaipeda sustainable development opportunities tackling the following tasks: (1) Assessing Klaipeda port and the projected deep-water port of the current environment state; (2) Assessing the impact of the water quality of Klaipeda port, depending on the intensity of activity; (3) Assessing the

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.

This paper is a continuation of the research into the astronomical reasons behind prehistoric rock and mobiliary art in the Iberian Peninsula, the first part of which was presented in the previous SEAC Congress celebrated in 2007 in Klaipeda (Lithuania). It proposes that all heavenly objects painted as rock art and on ceramic pieces be given the name of astraliformes [=solar and stellar paintings]. The six astraliformes from the two shelters visited, and the ceramic pieces on which astraliformes appear in the Prehistoric Museum of Granada are presented. Astraliformes appear in schematic art in a sudden manner and on a large scale, and are included in the panel because of their function as a means of regulating and promoting the agrarian cycle.

Water-quality control, monitoring and wastewater treatment in Lithuania 1950 to 1999.
Cetkauskaite, A; Zarkov, D; Stoskus, L

The Lithuanian water-management system developed on the basis of Soviet regulations in 1950-1990. Surface-water quality monitoring started in the 1950s, and the system was improved in the 1960s. Today, 48 rivers are being monitored using up to 70 parameters. Statutory monitoring of discharges started in 1962, wastewater standards were issued in 1957 and 1966, and then revised in 1996. Wastewater-treatment plants were built first in rural areas, in factories since the 1950s, and later in towns. Since 1991, large capacity municipal plants have been constructed with foreign assistance. Water quality has improved in some rivers since 1970, but Lithuania's main river, Nemunas, remains moderately polluted. The lower Nemunas is especially affected by discharges of municipal and industrial wastewater from Sovietsk and Neman (Russia), which account for half of the total loading. Hydrobiological data of 1994-1998 indicated the eutrophication of the Curonian Lagoon, and bacteriological pollution and blue-green algae blooms in the Baltic Sea north of Klaipeda.

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. Copyright © 2013 Elsevier Ltd. All rights reserved.

The samples from the proximal femora were taken from 12 cementeries from the Roman period. The skeletons date from the 1st-4th centuries A.D. Trace element analysis was used in order to reconstruct the basic diet. The sites that best corresponded to the model of Old Germanic diet described by ancient authors "meat, milk and cheese" were found in the Pruszcz Gdanski East Pomerania region close to the Baltic sea as well as in region Halle (Niemberg) and not far from Donau (Sládkovicovo). This diet is characterized by a large amount of protein and consequently of zinc. In the original Old Germanic region in a time period of more than 1000 years (from 400 B.C. to 700 A.D.) there is the same type of trace elements sources for bones and also the same type of the diet. This possibly distinguishes Germanic soldiers (aboriginal) from others groups in Roman legionary camps. It seems that the Donau River is very important for predicting the type of diet in the Roman period. North of the river animal component prevails south of the river vegetal component prevails. The rich agricultural land along the Donau River and in the Pannonian plains affects social arrangement as well as the structure of bones in Germans and Sarmats in the 2nd-4th centuries. Lead became a civilization element. It appeared in the diet of the Greek and Romans. Contamination varied with different social classes. We have found higher lead concentration in the femurs of the Germans than in those of the Sarmatians. The highest concentration we found was in Pannonian towns (Gorsium, Sopianae) and legionary camps (Straubing, Gerulata). In reference to age, the maxima of the highest lead concentrations in Gerulata II are between 11 and 13 years of age and between 40 and 50 years.

The aim of the present study was to analyze caries experience in relation to the occurrence of fluorosis in 12 year olds in a natural fluoride area. This cross-sectional study was conducted among 12-year-old lifetime residents (n = 301) of Klaipeda, Lithuania, where the natural fluoride content is 1.7-2.2 ppm F. Data collection included a clinical dental examination and an inquiry about toothbrushing habits. Dental caries was diagnosed according to the World Health Organization criteria and described in terms of decayed, missing, and filled teeth (DMFT)/decayed, missing and filled surfaces (DMFS) indices and decayed, filled surfaces (DFS) on selected proximal surfaces. Dental fluorosis was diagnosed according to the Thylstrup-Fejerskov (TF) index and categorized as none (TF = 0), mild (TF = 1-2), moderate (TF = 3-7), or severe (TF = 8-9). The χ(2)-, Kruskal-Wallis, and Mann-Whitney tests, Pearson's correlation, and linear regression served for statistical analyses. A total of 34% of the 12 year olds studied had no signs of fluorosis, while the rest had mild (42%) or moderate (24%) fluorosis. Caries experience was negatively related to the presence of fluorosis. When present (TF > 0), the mean DMFT was 1.8 (standard deviation [SD]: 1.7) versus 2.6 (SD: 2.3) in the absence of fluorosis (TF = 0, P = 0.008). The corresponding mean DMFS values were 2.6 (SD: 3.1) versus 3.8 (SD: 4.3, P = 0.014). The presence of fluorosis associates with lesser caries experience in 12-year-old lifetime residents of an area with moderately-elevated natural fluoride. © 2014 Wiley Publishing Asia Pty Ltd.

The spatial pattern of the hydrodynamic circulation of the Curonian lagoon, the largest European coastal lagoon, is still little understood. In absence of automatic current registration data all the existing models relied mostly on such data as water levels leaving high level of uncertainty. Here we present CISOCUR, a new project financed by European Social Fund under the Global Grant measure. The project applies a new methodology that uses the carbon stable isotope (SI) ratio of C12 and C13 that characterize different water sources entering the lagoon and may be altered by internal kinetic processes. Through the tracing of these isotope ratios different water masses can be identified. This gives the possibility to validate several hypotheses of water circulation and validate hydrodynamic models. In particular it will be possible to 1) trace water masses entering the lagoon through the Nemunas and the Klaipeda strait; 2) test the hypothesis of sediment transport mechanisms inside the lagoon; 3) evaluate the importance of physical forcing on the lagoon circulation. The use of a hydrodynamic finite element model, coupled with the SI method, will allow for a realistic description of the transport processes inside the Curonian lagoon. So the main research goal is to apply the stable isotope tracers and a finite element model to determine the circulation patterns in the Curonian lagoon. Here we show how the SI analysis was used to validate the hydrodynamic model on the basis of residence time. The average residence time of the Nemunas waters is estimated through SI data and is then compared with the model data computed through standard algorithms. Seasonal changes of carbon content are taken care of through a preliminary application of a carbon kinetic model. The results are compared to literature data.

Impact of heavy metals on the oil products biodegradation process.
Zukauskaite, Audrone; Jakubauskaite, Viktorija; Belous, Olga; Ambrazaitiene, Dalia; Stasiskiene, Zaneta

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

So the main research goal is to apply the stable isotope tracers and a finite element model to determine the circulation patterns in the Curonian lagoon. Overall, the project will develop according to 4 main phases: 1) A pilot study to measure the isotope composition of different carbon compounds (dissolved and suspended) in different water bodies that feed water into the central lagoon. Through this pilot study the optimal study sites for the seasonal campaign will be identified as well. 2) Seasonal field campaigns in the monitoring stations identified in phase 1 to measure the carbon isotope ratio. 3) Development of a model that describes the kinetics of carbon isotopes and its transformation. 4) Application of a hydrodynamic model
