    Sammanfattning : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. LÄS MER

  3. 2. Removal processes in sewage treatment plants : Sludge quality and treatment efficiency of structurally diverse organic compounds

    Författare :Ulrika Olofsson; Peter Haglund; Staffan Lundstedt; Juliane Hollender; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmetrics; flame retardants; GCxGC; non-targeted screening; mass flow; metals; plasticizers; poorly removed contaminants; POP; PPCP; prediction; Principal Component Analysis; removal efficiency; sewage; sewage treatment plants; sludge; sludge adsorption; sources; time-trend analysis; Environmental chemistry; Miljökemi;

    Sammanfattning : Large and ever-increasing numbers of chemicals, including large quantities of a broad spectrum of organic compounds are used in modern society. More than 30 000 of the more than 100 000 chemical substances registered in the EU are estimated to be daily used, of which many will be discharged into the waste-streams handled by municipal sewage treatment plants (STPs).

  4. 3. Mid-Holocene mineral dust deposition in raised bogs in southern Sweden : Processes and links

    Författare :Jenny Sjöström; Malin Kylander; Carl-Magnus Mörth; Bindler Richard; Lisa Belyea; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paleodust; peat; geochemistry; mineralogy; REE; Holocene; peat accumulation rates; paleostorms; Marine Geology; maringeologi;

    Sammanfattning : Atmospheric mineral dust is a key component of the climate system, which affects insolation, brings nutrients to marine and terrestrial ecosystems, and acts as a cloud condensation nuclei. To reconstruct past patterns in terrestrial dust deposition natural archives may be utilized, such as loess, dunes, lakes, and peat bogs. LÄS MER

  5. 4. Ecosystem response to dam removal

    Författare :Anna G.C. Lejon; Christer Nilsson; Birgitta Malm Renöfält; Emily Stanley; Umeå universitet; []
    Nyckelord :dam removal; macroinvertebrates; plant species; plant succession; restoration; riparian zone; sediment deposition; species richness; Sweden; biology; biologi; ekologisk botanik; Ecological Botany; hydrologi; Hydrology;

    Sammanfattning : This thesis aims to improve our understanding of how riverine ecosystems respond to dam removal. Riverine and particularly riparian ecosystems are among the most variable and important features of all landscapes. LÄS MER

  7. 5. Targeted and untargeted analysis of organic contaminants from on-site sewage treatment facilities : Removal, fate and environmental impact

    Författare :Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; decentralized sewage treatment; wastewater; surface water; environmental fate; bioavailability; removal efficiency; mass fluxes; biochar; environment; GC×GC-MS; LC-IM-MS; mass spectrometry; contaminants; pollutants; prioritization; non-target analysis; screening; analytisk kemi; Analytical Chemistry;

    Sammanfattning : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.
