1. Risk-Based Decision Model for Microbial Risk Mitigation in Drinking Water Systems
Sammanfattning : Microbial risks in drinking water systems can cause sporadic pathogenic infections and waterborne outbreaks resulting in large costs for society. In 2010 for example, around 27,000 persons were infected with Cryptosporidium in Östersund, Sweden. LÄS MER
2. Improved life cycle assessment of wastewater and sludge management with resource recovery
Sammanfattning : Around the world every day, large amounts of wastewater are treated before release, to avoid impacts on humans and the environment. The treatment requires resources in the form of energy and chemicals, and it generates large amounts of sewage sludge, however, it can also serve as a source of energy, nutrients and carbon. LÄS MER
3. Fresh Perspectives on the Assessment of Sewage Sludge Management
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).

4. Microbial Risks in Surface Water Sources
Sammanfattning : Microbial risks need to be properly handled for the provision of healthy drinking water. The mitigation of pathogens in the water source lowers the risk for infection associated with nominal and suboptimal drinking water treatment. LÄS MER
5. Risks and benefits of drinking water treatment : focusing on child health and prenatal development
Sammanfattning : Drinking water is our most important food item and its access is indispensable for a wellfunctioning society. Recent Swedish water-borne outbreaks have demonstrated a system vulnerability and a clear need for improved knowledge on how variations in drinking water quality affects our health. LÄS MER
