1. Removal processes in sewage treatment plants : Sludge quality and treatment efficiency of structurally diverse organic compounds
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. Health of municipal sewage workers : Studies of cancer incidence, biomarkers of carcinogenicity and genotoxicity, and self reported symptoms
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. Antimicrobials in sewage treatment plants : occurrence, fate and resistance
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. Sustainable Sewage Sludge Management : Addressing Multidisciplinary Challenges
Sammanfattning : This PhD thesis focuses on multidisciplinary challenges in sewage sludge management and how they can be addressed to increase sustainability. Sewage sludge is the residual from wastewater treatment. It contains both resources and contaminants making its management challenging. LÄS MER
5. Metal Speciation and Toxicity in Sewage Sludge
Sammanfattning : Increasingly stringent controls on metal concentrations in sewage sludge destined for agricultural application provided a basis for the study of the relevance of metal speciation in sewage sludge. A comprehensive literature review identified difficulties in relating metal speciation through single chemical extractions to plant uptake and soil toxicity. LÄS MER
