The focus of this study was to examine the nutrients and benthic organisms of the bay ?Mönsteråsviken?, which is influenced by eutrophication. The purpose was also to look at an interesting gradient forming in the bay, namely the distance from the river outflow of Lillån. At 18 sampling sites in the bay samples of water, sediments and benthic organisms were collected in late April of 2011. The water was analyzed for nitrate, phosphate and chlorophyll.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

The purpose of this study is to examine the phenomenon ?Living library?, where people are lent out instead of books. First it is looked into what the Living library means to the person who is borrowing a living book and what it means to the living book itself. Than the Living library is put in a public library context. This is done through a case study of the city library of Helsingborg and the city library of Malmö.

With my bachelorwork I aimed to design a new mobile ?livingspace? which should become as small, functional andeasy to assemble as possible.The ?living space?is made for people who are interested inhaving a biking vacation and getting more close to naturebut at the same time wish to have a comfortable and easyway of traveling and living. The ?living space? is a multipurposevehicle which you transport with a bicycle. Thevehicle contains a kitchen with workspace, a refridgerator,space for luggage and a comfortable sleeping space.In my workingprocess I made research, sketches and modelsto find a functional solution..

Agricultural drainage ditches are links between fields, lakes and oceans, having the potential to transport e.g. sediment and nutrients. When in a good condition, drainage ditches can act as sinks for e.g. phosphorus and sediments and prevent eutrophication downstream. The aim of this study was to determine the condition of one agricultural drainage ditch and to come up with suggestions for appropriate measures. The aim was also to determine which of the ditch?s properties that were possible to evaluate visually, which processes they represented as well as which properties required complementary physical analysis. This in order to contribute to the work of developing a method for determining the status/condition of agricultural drainage ditches.

Längs den svenska kusten verkar landhöjningen, en process där landet höjs efter den senaste istiden. Mest påtaglig är landhöjningen i Östersjön. Till följd av landhöjningen avsnörs grunda havsvikar från havet och bildar nya sjöar, så kallade flader, gloflader och glon. Målet med denna studie var att undersöka sediment från olika provtagningspunkter i en gloflad i Gårdskärsområdet i Lövstabukten (norra Uppland), för att se hur fördelningen av olika arter av kransalger varierat i glofladen under åren när miljön successivt förändrats. För att undersöka detta har oosporförekomst från kransalger i sediment studerats.

Fosfor (P) är ofta det begränsande ämnet i akvatiska system och kan i höga mängder bidra till övergödning i sjöar och hav. För att minska tillförseln av partikelbunden fosfor som läcker från jordbruksmark kan våtmarker anläggas i avrinningsområdet. För en effektiv avskiljning är det viktigt att partiklar sedimenterar i våtmarken och stannar i sedimentet. Studier har visat att vissa karpfiskar och märlkräftor genom bioturbation kan orsaka resuspension av partiklar, samt att effekten ökar med ökad täthet. Syftet med denna studie var att undersöka om även makroevertebraten Asellus aquaticus (sötvattensgråsugga) kan orsaka resuspension av partiklar.

Globally, coastal ecosystems like mangrove forests, sea grass meadows and salt marshes are well known for their ability to capture and store atmospheric carbon effectively. In Sweden, there is still limited knowledge about local coastal ecosystems with similar functions, with alder swamp forests being an interesting example. Therefore, this study aimed to increase knowledge of the factors that can contribute to the potential carbon sequestering ability of alder swamps. Vegetation data and sediment samples were collected from a total of 37 sampling plots across four alder swamps in Bohusl?n on the Swedish west coast.

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

Living Lab är en öppen innovationsmiljö där innovationer samproduceras, testas och verifieras av användarna, tillsammans med företag och akademin i en kontext som representerar innovationens tänkta användningsområde. Genom samverkan kan olika värden skapas för företagen. Syftet med uppsatsen var att undersöka hur Living Lab skapar värde för företag och vilka värden företag kan identifiera ur de användarcentrerade aktiviteterna. Uppsatsen karaktäriseras av en kvalitativ ansats och grundar sig i en explorativ undersökning med djupintervjuer där fyra företag ligger till grund för uppsatsens resultat. Uppsatsen har visat att Living Lab skapat värden för företag genom att de fått mer tilltalande produkter, identifierat nya användarkategorier och samordnat resurser med företag.

Th is essay is the final piece of my eduacation. The essay contains material that have beenproduced from a study that have been made in Majviken, Gothenburg, one of many cohousingcommunitys in Sweden. The special quality this building poses is that is was originally built as acohousing living but in the past 25 years is has been a housing estate without any form of servicefunction included.During the last year the whole house have been remodeled and a new kind of livingconcept havebeen created, a lifestyle living with many different kinds of service functions included, hostess,common premises for the residents with things suchs as gym, saunas, movietheater and relaxationareas.The study is about the residents living in Majviken, and how they feel about the new way ofliving but also how it affect their lives. What do the new living lifestyle stand for?My original intention have also been to observe and make interwievs with the residents to capturetheir thoughts and in the end have the possibilty to summarize and compare how it was before theredmodeling..

Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.
