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

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Ulrika Olofsson; Umeå universitet.; [2012]
    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; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi 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).

  2. 2. Health of municipal sewage workers Studies of cancer incidence, biomarkers of carcinogenicity and genotoxicity, and self reported symptoms

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lennart Friis; Uppsala universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; Abdominal symptoms; alkaline single cell gel assay; asthma; cancer; comet assay; dyspepsia; genotoxic exposure; Helicobacter pylori; IBS; occupational epidemiology; respiratory symptoms; sewage workers; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The occupational exposures of sewage workers are complex and variable, and include a great variety of biological and chemical agents. Previous research has focused mostly on infections and various symptoms among sewage workers, e.g. abdominal and respiratory symptoms. LÄS MER

  3. 3. Antimicrobials in sewage treatment plants occurrence, fate and resistance

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Marcus Östman; Umeå universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

    Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER

  4. 4. Fresh Perspectives on the Assessment of Sewage Sludge Management

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Robin Harder; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; life cycle assessment; biosolids; land application; sewage sludge; pathogen risk; risk assessment; life cycle impact assessment; human toxicity; wastewater; chemical risks;

    Sammanfattning : Sewage sludge management and its role in closing nutrient cycles have received considerable attention in recent years. This thesis quantified phosphorus flows in Gothenburg, Sweden, under current and possible future waste management practices, and aimed to improve the assessment of wastewater and sludge management from an environmental and human health perspective through blending risk assessment (RA) and life cycle assessment (LCA).

  5. 5. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Annica Lindqvist-Östblom; Linköpings universitet.; Linköpings universitet.; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

    Sammanfattning : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. LÄS MER
