6. Feasibility study of soil washing to remediate mercury contaminated soil
Sammanfattning : Mercury (Hg) cannot be degraded. Therefore only two principal processes are available for the treatment of Hg-contaminated soil: (1) the separation of Hg from the soil or (2) the stabilisation of Hg within the soil. Prior to selecting a suitable treatment technique, it is necessary to have an understanding of Hg behaviour in contaminated soil, i.e. LÄS MER
7. Fluvial transport and risk of mercury in a gold mining area
Sammanfattning : My thesis is part of an overall environmental program evaluating the environmental and human health stress in areas of Nicaragua affected by anthropogenic emission of metals and man-made organic substances. I examine the fluvial transport of mercury contextually associated with the extent of the contamination and the observed human and environmental stress in a gold mining area. LÄS MER
8. Lidar Techniques for Environmental Monitoring
Sammanfattning : Atoms and molecules absorb and emit light at certain, welldefined wavelengths, and this forms the basis of spectroscopy. The wavelengths are given by the discrete energy levels of the atoms/molecules. LÄS MER
9. Estimating qualities and quantities of faecal sludge to determine resource recovery potential : A case study in Phnom Penh, Cambodia
Sammanfattning : A paradigm shift to convert faecal sludge into resources could minimise environmental pollution and public health risks in cities in low- and middle-income countries (LMIC). To support faecal sludge management planning at city scale, this thesis investigated resource recovery potential from faecal sludge, using Phnom Penh as a case and focusing on waterborne systems.

10. Removal of metals from contaminated waters : Evaluating the use of synthetic adsorbents and green algae biomass
Sammanfattning : Metal contamination of water bodies has attracted global attention owing to its environmental toxicity, abundance and persistence. Metals such as arsenic, cadmium and mercury are of greater concern since they are toxic even at low concentrations. LÄS MER
