6. LCA of Egg Phospholipids
Master-uppsats, KTH/Industriell ekologiSammanfattning : Egg phospholipids are a group of fats or lipids in the egg yolk, commonly used as emulsifiers in the chemical industry to facilitate the dissolving of substances. The pharmaceutical company Fresenius-Kabi manufactures this product and seeks a better understanding of the product’s major environmental impacts in order to comply with the ISO 14001 requirements, communicate its environmental performance and choose raw materials that result in lower environmental impacts.

7. Epiphytic lichens associated with different traffic intensities along the highway E4
Master-uppsats, SLU/Dept. of EcologySammanfattning : Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites.

8. Treatment Technology for VOC Emissions from Oil Refineries : Case study of measures taken to minimize VOC emissions at Swedish petrochemical companies to be appiled at Chineses Refineries
Master-uppsats, KTH/Industriell ekologiSammanfattning : The aim of this thesis is to give suggestions on what measures to take to improve the VOC emission situation in refineries in Tianjin, China, through existing technologies in refineries in Sweden. This has been done by identifying the main places of leakage in oil refineries in Sweden, identifying what VOC compounds are emitted from the plants and the amounts emitted, mapping out different measures taken by oil refineries in Sweden to minimize VOC emissions, evaluating the different measures and suggesting how to move forward with VOC control in Tianjin.

9. Undersökning av avgasemissioner till vatten från dieselinombordsmotorer i fritidsbåtar : En jämförande studie av olika bränslen
Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaperSammanfattning : In this Masters Thesis emissions to water from diesel engines in pleasure boats when driven with alternative fuels have been investigated. Two alternative fuels, Fischer-Tropsch-diesel (FT-diesel) and a blend of FT-diesel and rapeseed methyl ester (RME) have been compared with diesel of Swedish environmental class 1 (diesel EC1).

10. Soil and groundwater contamination with gasoline and diesel oil : assessment of subsurface hydrocarbon contamination resulting from a fuel release from an underground storage tank in Vanstad, Skåne, Sweden
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Spills and leaks from storage tanks constitute the most common groundwater contamination source with petroleum products. Gasoline and diesel pools do not spread extensively along the water table, but dissolved constituents are transported in groundwater on relatively larger distances. LÄS MER
