2. 1. Navigating towards environmental impact assessment of shipping

   Author : Anna Lunde Hermansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; DAPSIR; scrubbers; metals; polycyclic aromatic hydrocarbons; marine environment; ship pollution;

   Abstract : The shipping sector exert multiple pressures on the environment, affecting climate change, human health and the marine environment. From a policy perspective, shipping is usually assessed based on the emissions to air (e.g. READ MORE

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

   Author : Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
   Keywords : 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;

   Abstract : 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.

5. 3. A Deep Dive into Sediments : Exploring approaches to assess environmental risks and achieving environmental goals in management of contaminated sediments in Sweden

   Author : Peter Bruce; Clare Bradshaw; Yvonne Ohlsson; Anna Sobek; Sabine Apitz; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sediment; risk assessment; risk evaluation; risk management; contaminants; regulations; weight of evidence; line of evidence; environmental goals; environmental management; guidelines; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Contaminated sediments are common, especially near urban and industrialized areas, and they can have negative ecological effects. In three studies, I explore the challenges for environmental management of contaminated sediments, focusing on environmental risk assessment (ERA) in Sweden. READ MORE

6. 4. Contaminants of Emerging Concern in Swedish Freshwater Environments: Sources, Occurrence, and Impacts

   Author : Daniel Malnes; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Contaminants of emerging concern (CECs) is one of several reasons for the deterioration of surface water quality globally, even though the CECs occur in trace concentrations. This thesis produced new CEC data through a oneyear field study for substances which occur in Sweden’s three largest lakes and their associated rivers. READ MORE

7. 5. Wide-scope screening for contaminants of emerging concern in archived biota: Method development, suspect prioritisation, and non-target screening in a novel identification tool

   Author : Wiebke Dürig; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Environmental monitoring of hazardous chemicals in wildlife conventionally uses target screening for selected contaminants, but relatively few contaminants are moni-tored and knowledge of potentially hazardous contaminants of emerging concern (CECs) in wildlife is lacking. In this thesis, a non-target screening (NTS) method com-bined with temporal trend analysis was developed and applied as a prioritisation tool for identification of CECs in top predators, using high-resolution mass spectrometry (HRMS).
