2. 1. Risk-Based Decision Model for Microbial Risk Mitigation in Drinking Water Systems

   Author : Viktor Bergion; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; drinking water; quantitative microbial risk assessment; cost-benefit analysis; health risk; contaminant fate and transport modelling; economic valuation of health effects; pathogen;

   Abstract : 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. READ MORE

4. 2. Microbial risk assessment and its implications for risk management in urban water systems

   Author : Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; Vatten i natur och samhälle;

   Abstract : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. READ MORE

5. 3. Fresh Perspectives on the Assessment of Sewage Sludge Management

   Author : Robin Harder; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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).

6. 4. Ticks - ecology, new hazards, and relevance for public health

   Author : Thérese Janzén; Monica Hammer; Patrik Dinnétz; Mona Petersson; Lars Korslund; Södertörns högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea region; eco-epidemiology; habitat; Ixodes persulcatus; Ixodes ricinus; landscape; risk; urbanization; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Abstract : Ticks and tick-borne diseases are ranking second only to mosquitoes as vectors of pathogens responsible for diseases in both humans and domestic animals. In the countries around the Baltic Sea, two medically important tick species are increasing both in range and abundance, and the public health threat posed by tick-borne diseases in this area is steadily growing.

7. 5. Novel cardiovascular risk factors in childhood

   Author : Michal Odermarsky; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; environmental tobacco smoke; vascular function; infection; type 1 diabetes; HLA;

   Abstract : Individuals with type 1 diabetes (T1D) have a 2 to 3-fold increased risk for cardiovascular disease compared to non-diabetic subjects. Exposure to a broad panel of risk factors in childhood may cause vascular damage with potentially long-term consequences for cardiovascular morbidity. READ MORE
