Acid Sulfate Soils in Västra Götaland, Sweden
(2021-07-06)Acid sulfate soils can cause significant economic, environmental, and health-related issues due to acidification and metal leaching. This thesis investigates the presence of acid sulfate soils in the county of Västra ... -
Acid sulphate soil in Falkenberg on the west coast of Sweden - The first discovery of active acid sulphate soil outside the Baltic Basin
(2020-09-09)Active AS soil has several negative impacts on the environment due to their ability to severely decrease pH-values and mobilize metals bound in the soil. The negative impacts can especially be seen in aquatic environments ... -
Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden
(2021-03-10)Acid sulphate soils have been referred to as being among the most harmful soils in the world due to their ability to severely decrease the pH of the water, consequently enabling an increased metal load to recipient water ... -
Air quality, indoor and outdoor. A study of connections between indoor and outdoor concentrations: NO2, CO2, PM10 and PM2.5
(2020-06-29)Air pollution is a hazard to human health and especially vulnerable are those who live in urban areas. Urban areas are undergoing fast driven urbanization which often results in increased air pollution. Since different ... -
An Assessment of Wadis as Suitable for Wastewater Treatment, in a Semi-Arid Region with Limited Data Access – Aleppo, Syria
(2020-07-08)As a consequence of the conflict in Syria, the wastewater treatment plant in southwestern Aleppo has not been fully functioning since 2013, and wastewater is released into the Queiq River without adequate treatment. ... -
Analysis of nutrient content in rocks from New South Wales A study of nutrient content in sedimentary and igneous rock samples within the wider Blue Mountains and Sydney Basin, New South Wales, Australia
(2022-09-01)Nitrogen, phosphorus and potassium are three of the main nutrients for the primary functioning of all biological life. These elemental nutrients are abundant in terrestrial systems and the lithosphere, where microbes and ... -
APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN
(2023-08-18)In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the ... -
Ash distribution and cavities in Icelandic glaciers, a marker for snow accumulation and radar signal velocity change
(2020-01-15)Glaciers in the geologically active Iceland has a high scientific as well as touristic value. In this thesis, the two largest glaciers on Iceland have been studied with GPR to find if the method is suitable to use in ... -
