DEHP - från mjukgörare till hormonstörande

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Fick algblomningen i Östersjön 2005 några ekonomiska effekter? : Fallet turistnäringen på Gotland

Algal bloom is a naturally occurring phenomenon and occurs in all waters around the world but in recent years, algal bloom in the Baltic Sea has become more massive and more widely spread. When an algal bloom negative effects on the seawater quality, it may have an impact on tourism in the Baltic Sea. The aim of this thesis is to study, through a survey based on a production function approach, whether an environmental change as algal blooms, influenced the Gotland tourist accommodation industry and their "production of attractive overnight? in the summer of 2005. The results show that algal blooms did not have a great impact on companies ?production of attractive accommodations".

Energisystem med utnyttjande av restprodukter för gödsling av Salixodling för energiproduktion : studier av kretslopprojektet i Enköping och dess applicering på en kommun i Ryssland.

The purpose of this work is to study a circulation project in Enköping municipality, where the society?s rest products are used to make beneficial products. In Enköping the rest products from waste treatment plants and private sewers are used to fertilize and irrigate Salix plantations that later are harvested and burned at the local combined heating and power plant, ENA Energy AB, to produce electricity and heat. Possibilities to apply this kind of project ona municipality in Russia are also explored.Guryevsk municipality in Kaliningrad region was chosen since there is a need to improve energy systems and reduce emissions to water and air. This municipality strives to become environmentally friendly.

Födosammansättning hos gråsäl (Halichoerus grypus) samt test av flotte för insamling av sälfekalier.

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Dynamisk massbalansmodellering av fosfor i Östersjön

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar

Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.

Utbildning för hållbar utveckling : En studie av de möjligheter, svårigheter, kunskaper och erfarenheter som präglar utbildning för hållbar utveckling idag

I enighet med bland annat Agenda 21, Baltic 21 Education och FN:s årtionde för utbildning för hållbar utveckling ska Sverige omorientera sina utbildningssystem så att de stödjer en hållbar utveckling. Denna uppsats syftar till att undersöka vad utbildning för hållbar utveckling innebär för lärare i grundskolans högre årskurser,genom att identifiera och undersöka anknutna möjligheter, svårigheter och erfarenheter. Detta har gjorts utifrån en teoretisk litteraturstudie och en kvalitativ fallstudie. Den teoretiska studien baserades på vetenskaplig litteratur såväl som internationella och nationella styrdokument, överenskommelser och undersökningar et cetera. För fallstudien genomfördes fem djupintervjuer med lärare.

Rederiers hantering av nya miljökrav : En studie om Birka Cruises, Tallink Silja och Viking Lines arbete med ekonomisk och miljömässig hållbar utveckling

The purpose of this study is to examine how Viking Line, Tallink Silja and Birka Cruises work with economic and environmental sustainability, and also to see how they work with new environmental legislations. In 2015 a new environmental legislation will be introduced, by the name Sulphur directive. The Sulphur directive entails a reduction in Sulphur dioxide emissions from ships where the emissions cannot exceed 0,1 percent. There are three alternatives to achieve the new environmental legislation, the use of Marine Gas Oil, LNG or scrubbers. All three alternatives will lead to increasing costs for the shipping industry.

Ut ur Östersjön genom vassen : beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter

This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts. Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance. This literature has illuminated a major environmental problem and it has been suggested optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a definite answer for the optimal method for each site tests should be carried out, this because many factors determine to what is suitable for each, specific environment. .

Politiska nätverk och Nord Stream : En möjlighet att vara med och påverka

AbstractPaper in political science, C-level, by Lars A Roos, spring semester 2007. Tutor: Susan Marton. ?Policy networks and Nord Stream.?The purpose of this paper is to examine how the government and interest groups have been working together to commonly prevent the building of a gas pipeline in the Baltic Sea. To do this, a comprehensive question how does the government and the involved interest groups work together in policy networks? has been broken down to three more specific questions: (1) Can the cooperation between the government and the interest groups be placed within the frame of a issue network or a policy community? (2) Has the cooperation between the government and the interest groups contributed to new tools for the government to prevent the gas pipeline? (3) If the answer is yes to the second question then, which are these new tools?My examination is a case study of the policy network that exists around the Swedish actors in the case of the Baltic Sea gas pipeline.

Är Mahans teorier kring sjöherravälde tillämpbara på ubåtskrigföring?

Uppsatsen beskriver vad som kännetecknar och omfattar begreppen sjömakt och sjöherravälde. Detta mynnar ut i en studie av Mahans teorier för att etablera, utöva och bestrida ett herravälde till sjöss. Här har teorierna kring avgörande slag, sjöfartskrig och ?fleet in being? valts ut för att avgränsa arbetet.Syftet med uppsatsen är att undersöka om Mahans teorier för att etablera, utöva och bestrida ett sjöherravälde går att tillämpa på ubåtskrigföring. Utifrån historiska händelser kring sjöfartskriget mellan Nazityskland och Storbritannien under andra världskriget samt stridigheterna mellan Argentinska flottan och den brittiska under Falklandskriget, undersöks det ifall Mahans teorier är tillämpbara på den ubåtskrigföringen som fördes i respektive fall.
