Undersökningsmetodik för klorerade lösningsmedel i marken

Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.

Slemhinneskadors inverkan på salivens innehåll av IgG och IgA

In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

Vill EU vända på steken? : En kritisk analys av EU-kommissionens ställningstagande i frågan om animalieproduktionens klimatpåverkan

This thesis examines the ongoing European political debate on the links between livestock production and climate change. In the end of 2006 the UN Food and Agriculture Organization (FAO) released their report Livestock?s long shadow, showing that livestock production represents some 18 % of the total global greenhouse gas emissions. The purpose of this paper is to explore the European Commission?s position and response to this question since the release of the report.Using Arne Naess? argumentation analysis, statements made by the Commission will be systematically organized and broken apart.

Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.

A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.

Diakoni och Välfärd - en kvantitativ studie av ekonomiskt stöd inom Svenska kyrkan

The aim of this thesis was to study financial support within the Church of Sweden and the view of the church?s diaconal work. This was done with a quantitative method where a survey sent to a number of churches containing questions about financial support within the church and how they, the respondents, looked at the church?s role as a welfare agent. Of the almost 200 congregations only 23 congregations responded.

Flavan-3-oler och endotel -dysfunktion

Background: Flavan-3-ols are polyphenolic phytochemicals belonging to the flavonoids. Flavan-3-ols are present in many higher plants and are particularly concentrated in e.g. Camellia sinensis (tea) and Theobroma cacao (cacao) and have got attention due to their antioxidative capacity. Many studies have been able to associate flavan-3-ol-rich foods to improved endothelial function. The aim of the present work is to review the scientific literature and evaluate the evidence for positive effects of flavan-3-ols on endothelial dysfunction in humans. Method: Scientific articles describing intervention and observational studies about flavan-3-ols and endothelial dysfunction, were searched for on http://www.pubmed.org.

Private-Public Partnerships (PPP) : collaborating for a sustainable business in Sweden

Är ekologiska slaktkycklingar sjukare än konventionella?

Den ekologiska produktionen styrs av många olika lagar och regler som den konventionella produktionen inte behöver följa. Dessa regler kan ses som en välfärdsgaranti i den ekologiska slaktkycklingproduktionen då reglerna främst är skrivna för att kycklingarna ska kunna utföra sina naturliga beteenden i en passande miljö. Rastgårdar ska finnas till de ekologiska kycklingarna för att de ska få beta, få motion och få chansen att bygga upp sitt naturliga immunförsvar. I många fall ses rastgården som en positiv aspekt av den ekologiska produktionen, men det finns även problem relaterade till utevistelsen då exempelvis vilda djur kan lockas till slaktkycklingarna och på så vis stressa upp dem, smitta dem med parasiter och patogener eller äta upp dem. Det är vedertaget att den ekologiska produktionens dödlighet är högre än den konventionella produktionens på grund av rovdjuren och sjukdomarna och de ekologiska kycklingarna utsätts i många fall för fler smittorisker på grund av utevistelsen.

Barnen som inte fanns : En kvalitativ studie baserad på självbiografier med fokus på individers upplevelse av omsorgssvikt

The aim of this study was to describe and understand how individuals in adulthood experienced a childhood with neglect, and how they handled neglect. In order to reach the perspective of the individuals who grew up with neglect, we chose to use autobiographical books as our empirical material. The criteria the autobiographies had to meet in order to fall within the scope of this study was that the biographies had to display the experience of neglect during childhood, and thereto the books had to be written by individuals who themselves experienced neglect. Based on the aim of this study we sought answers to three questions: How do the individuals describe their upbringing with a mentally or socially disabled parent? How have the individuals coped with the neglect they?ve been exposed to? What consequences have the neglect supposedly led to? The findings of this study show that the extent to which the individuals experienced neglect were profound and comprising.

Konsumenters attityder kring livsmedel och livsmedelssäkerhet

Konsumenters attityder till livsmedel och olika aspekter av livsmedelssäkerhet undersöktes i en intervjustudie i Upplands län, i vilken olika frågor kring attityder till livsmedel med fokus på livsmedelssäkerhet ingick. Resultatet visade att det absolut viktigaste för konsumenter när de väljer varor är att livsmedlet smakar gott, då samtliga respondenter uppgav att detta var viktigt. Att konsumenter oroar sig mer för toxiska restsubstanser såsom läkemedelsrester och bekämpningsmedelsrester än för livsmedelsburen smitta framkom, liksom att få uppfattar sitt eget hem som en plats där man kan bli matförgiftad, trots att tidigare studier visat att en stor andel av matförgiftningsfall smittas i sitt hem. Oroande stora andelar av konsumenterna kunde tänka sig att äta olika livsmedel med förhöjd risk att drabbas av matförgiftning såsom otillräckligt upphettad kyckling, och ett flertal enkla men viktiga hygienåtgärder för att undvika korskontaminering uppfattas inte av konsumenterna som viktiga att utföra, vilket kan leda till onödigt många matförgiftningsfall. Djurvälfärd och livsmedelssäkerhet är beroende av varandra och aktuellt arbete visar att svenska konsumenter anser att djurvälfärd är viktigt..

Animaliska restprodukter vid köttproduktion : Effektiv användning och livsmedelspotential

This master thesis aims to investigate and quantify the potential associated with increasing the usage of edible by-products as food for human consumption on the Swedish market. The main emphasis is on the Swedish production of offal and the obstacles that currently inhibit greater usage of these products as foods.The results indicate that the Swedish market for offal is limited. Only a small amount of the edible by-products that are produced in Sweden every year are consumed as foods and a considerable amount seem to be downgraded into animal feed or thrown away. The utilization of these products is restricted by economical, technical, legal, and cultural factors that all need to be taken into consideration. On the whole, large-scale slaughter plants seem to be more inclined to utilize these products effectively, as the profit from doing so increases proportionately to the produced volumes.

Utvärdering av jetomrörning : En studie gällande utvärdering av omrörningssystem vid Ekeby reningsverk

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.

Nötkreaturens val av betesvegetation på naturliga betesmarker :

This study concerns the type of vegetation selected by cattle grazing on semi-natural pastures, and whether the selection depends on the nutrient content of the vegetation or on other factors. The study was carried out in three different semi-natural pastures in the Uppsala area during June, July and August in 2006. The three pastures were first surveyed, mapped out and divided into sub-areas with regard to the type of dominating vegetation. The vegetation types identified were: wet, mesic, dry, wooded, pasture with signs of former cultivation (arable). Within each vegetation type three 1x1 m sampling plots were laid out. The grazing behaviour of the cows was recorded in a behaviour study.

Perfluoroalkyl substances in Arctic birds : a comparison between glaucous gulls and black guillemots from Svalbard

Perfluoroalkyl substances (PFASs) are ubiquitous in the environment today and they have been detected even in remote areas such as the Arctic. PFASs can be transported by the atmosphere and ocean currents but the transport mechanism is not fully understood. PFASs may be harmful to organisms due to their persistence in the environment, bio-accumulation potential and toxicity. Studies have shown that PFASs can cause adverse effects on the metabolism as well as the endocrine- and reproduction systems in organisms. In this study, PFASs were investigated in glaucous gull (Larus hyperboreus) (n=5) and black guillemot (Cepphus grylle) (n=4) from Svalbard.
