Metodutveckling för analys av PBDE och HBCD i sediment

Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. Fishes has shown increased contents of these substances, especially fat fish, since brominated flame retardants tends to accumulate in fatty tissues. They are also regarded as persistent and that gives them the ability to travel long distances. What also is really scary is that increased levels of brominated flame retardants have been detected in human breast milk. The knowledge of the brominated flame retardants is limited and not so much research has been done in this field. There are many reasons though, to keep the research going. Partly their structural resemblance to well-known toxics as PCB, but also their ability to accumulate in biological systems and enrich in food chains. In which way they affect humans we really don?t know yet.

Livskvalitet hos individer med multipla extremitetsskador : en tvärsnittsstudie

Syfte och frågeställningar: Syftet med denna studie var att undersöka hur individer med multipla extremitetsskador som hade genomgått utredning eller rehabilitering inom EX-Centers verksamhet upplevde sin livskvalitet. Frågeställningarna handlade om att jämföra gruppen med svenska populationsbaserade referensvärden och att undersöka om det fanns skillnader i livskvalitet mellan individer med medfödda eller förvärvade extremitetsskador och mellan kvinnor och män. Att undersöka om det fanns samband mellan SF-36 delområde Fysisk funktion och smärta i relation till övriga delområden och övergripande domäner samt samband mellan SF-36 självskattning i relation till kön, ålder, typ av skada, ortstorlek, sysselsättningsgrad eller civilstånd. Metod: 105 individer bjöds in till denna kvantitativa tvärsnittsstudie var av 62 (59 %) individer deltog i studien (33 kvinnor och 29 män, förvärvade (n=19) respektive medfödda (n=43) extremitetsskador). Livskvalitetformuläret Short Form 36 (SF-36) och frågeformulär om demografisk data användes.

Marknadsföring via sociala medier : Social Media Marketing

The thesis work focuses on marketing and its point of departure centers on mapping the utilization of social media as a form of marketing. The choice of this thesis subject has been deemed by the authors as one of particular interest due to the current popularity of social media in the Internet connected society and their use as marketing tools. Specifically, this thesis sets out to explore how companies exploit social media tools in marketing and how their use affects retail operations and customer relations in an effective and creative way.The report concentrates on qualitative data collection, the interview answers of four respondents, of which, two are considered experts within the field of social media. The choice of suitable respondents was strategic with the goal of covering as large a portion of the social media field as possible; one social media educator that works with companies and one who assists companies with social media applications. The remaining two respondents work in marketing and communications and employ, as part of their job, social media tools such as Facebook and Twitter.

What factors correlates with the use of game meat, wild fish, berries and mushroom in Swedish households : urban vs. rural areas

This study was made to see too what extent Swedes uses consumptive resources such as berries and mushrooms, game meat and meat from fish in their household on a yearly basis. I have also looked into the difference between rural and urban areas in Sweden. Further aim was to determine what factors that correlates with the participation in berry and mushroom picking and the use of game and fish meat within the household. The study was conducted in form of a mail survey that was sent to randomly chosen persons in every municipality in the six northern most counties in Sweden and in the county of Stockholm. In addition a sample was sent to randomly chosen persons on a national level.The results showed there is a difference in use between rural and urban areas in Sweden in all 4 investigated consumptive resources.

Om behovet av ett avrinningsområdesanpassat skogsbruk

The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015. The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.

Miljö- och hälsorisker med konstgräsplaner

In Sweden today many municipalities and sport clubs chooses to build artificial turfs becauseof the increased period of using the turfs during the year and less maintenance requirementsthan for natural grass fields. What could be problematic with artificial turfs is the rubbergranules used as infill material in the turf matt. The rubber granules are often made fromrecycled tires, which may contain for the human health and the environment, harmful substances.This was the reason why the Swedish Chemicals Agency commissioned a statusreport in 2006 which, among other things, concluded that the environmental and health risksassociated with granules made from recycled tiers in artificial turf fields were small, but thatthere could be a local environmental hazard. The purpose and objective of the risk assessmentwas to identify how artificial turf plans granules can affect recipients in the area closeto the pitches and provide input to reduce the spread of metals and substances harmful forboth human health and the surrounding environment. The work was divided into three parts:(1) the construction of artificial turf pitches and their material content, the spread of granulatesoutside the fields and disposal of artificial turf pitches.

Use of oxytocin to improve diagnosis of subclinical mastitis caused by Staphylococcus aureus

Mastitis, inflammation in the udder tissue, caused by S. aureus is a big problem in dairy cattle production. It causes suffering for the cow and curing or replacing the infected cow is costly for the farmer. It is known that beef cattle also suffer from mastitis caused by S. aureus.

En kvantitativ studie om köpbeslutsprocessen ? En undersökning inriktad på kvinnors konsumtion av konfektionsvaror till låga priser

Den svenska klädimporten har ökat dramatiskt och vårt samhälle har förändrats till ett konsumtionssamhälle där vi shoppar efter ?köp och släng? istället för ?slit och släng?. Den ökade klädkonsumtion är ett omdiskuterat samhällsproblem och mode är en färskvara som uppdateras i en allt snabbare takt. Ett stort utbud tillsammans med de låga priser som klädmarknaden är uppbyggd av uppmuntrar till impulsköp vilket gör det allt svårare för kunden att fatta medvetna köpbeslut. I denna studie kommer vi att utgå från Armstrong och Kotlers modell av köpbeslutprocessens som är uppbyggd av fem steg som innefattar hela processen.

Förekomsten av sura sulfatjordar i Mälardalen : -en pilotstudie utförd åt SGU

Acid sulphate soils is a wide spread problem along the northern coast of Sweden. This is causing great damage through low pH and leaching of metals out into the streams. These soils are estimated to be found in several places in Sweden but also in many other areas in the world. One of these areas in Sweden that are believed to contain these sediments is Mälardalen. The purpose of this study is to evaluate the extension of the acid sulphate soils in this area.

Tekniska möjligheter för artificiell spridning av renlav :

Forestry and reindeer husbandry are entitled to use the same land for their operations. For this reason, conflicts occasionally arise between them. Soil scarification is a forestry operation which has a negative effect on the occurrence of reindeer lichen. Reindeer lichens are of crucial importance to reindeers and reindeer husbandry, especially in the winter when reindeers primarily feed on different lichen species (Cladina spp. and Cetraria spp.).

Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.
