1. Multielement Urban Geochemistry : Exporing the Expected, the Unexpected and the Unknown
Sammanfattning : Urban areas are hot-spots for the human use of most elements. These elements are the building blocks of our various goods and chemicals and are used both purposely and in a more unaware fashion. There are many ways in which the elements get dispersed from the human use. Commonly acknowledged and evident processes of dispersion are point sources (e. LÄS MER
2. Fluoride in surface water and groundwater in southeast Sweden : sources, controls and risk aspects
Sammanfattning : The aim of this thesis is to determine the sources, controls and risk aspects of fluoride in surface water and groundwater in a region of southeastern Sweden where the fluorine-rich 1.45 Ga circular Götemar granite (5 km in diameter) crops out in the surrounding 1.8 Ga granites and quartz monzodiorites (TIB rocks).

3. Leaching of water-granulated iron silicate slags and their compounds : A study of synthetic and industrial slag systems
Sammanfattning : Copper smelter slag is a residue product of the pyrometallurgical extraction of copper. Due to its physical properties, the iron silicate type of copper smelter slag has many possible application areas, e.g., different aggregates and abrasives. LÄS MER
4. Environmental Effects of Agricultural Expansion in the Upper Amazon : A study of river basin geochemistry and hydrochemistry, and farmers' perceptions
Sammanfattning : In this thesis natural science is combined with environmental psychology in order to determine how deforestation and subsequent agricultural expansion in the Peruvian highland jungle has affected the natural environment and rural livelihoods. This region is part of one of the most biodiverse areas on Earth and is also exposed to high pressure from deforestation that threatens the ecosystems as well as the well-being of local populations.
