1. Assessing the biodiversity crisis within the Triassic-Jurassic boundary interval using redox sensitive trace metals and stable carbon isotope geochemistry
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Around the Triassic-Jurassic-Boundary time interval, a severe mass extinction event occurred, which has been associated to volcanism of the Central Atlantic Magmatic Province (CAMP). Significant amounts of greenhouse gases as carbon dioxide (CO2) or methane (CH4) and other volatiles are suggested to have been released into the atmosphere, leading to global warming with subsequent impact on the biosphere.

2. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle
Kandidat-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER
3. Arsenic and other heavy metals in hydropower plants : An assessment of occupational risk hazards at Fortum’s underground hydropower plants in Sweden
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Arsenic (As) is a metalloid that occurs naturally in the Earth’s crust, in bedrock and soil. The concentrations that Arsenic can be found are normally between 1-3 ppm. LÄS MER

5. Det var en gång – en trädgårdsgång : en litteraturstudie av markmaterial i svenska villaträdgårdar 1850 - 1950
Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Uppsatsen vänder sig till alla som äger, restaurerar, sköter eller har ett intresse för äldre trädgårdar och berör huvudsakligen de markmaterial som var vanligast förekommande i villaträdgårdar mellan 1850 och 1950. Gångar och markmaterial spelar stor roll för hur trädgården uppfattas och vilka signaler den sänder. LÄS MER
