2. 1. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

   Author : Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

   Abstract : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. READ MORE

4. 2. GETTING MORE OUT OF THE AFTERLIFE

   Author : Derek Diener; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MFA; remanufacturing; steel; company-level; Product EoL management; material efficiency;

   Abstract : Material intensity related to product consumption has become part of societal discourse and reducing it has become a priority of some industrial actors. Focusing on product end-of-life (EoL) is one approach that many companies and research entities have taken to identify and enact material intensity reductions. READ MORE

5. 3. Exploring logistics actions enabling environmentally sustainable freight transport

   Author : Vendela Santén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-operation; freight transport; actions; load factor; logistics; actors’ perspectives; sustainability; environment;

   Abstract : To curb unsustainable freight transport trends; such as transport growth, larger dependency on road transport and generally an increased share of greenhouse gas emissions from the sector, actions needs to be taken among actors in the logistics system. The purpose of this thesis is to explore logistics actions that enable environmentally sustainable freight transport. READ MORE

6. 4. Urban environmental stewardship : Roles and reasons for civic engagements in governance of social-ecological systems

   Author : Johan Enqvist; Maria Tengö; Örjan Bodin; Bengt Karlsson; Stockholms universitet; []

   Abstract : Stewardship as a concept is increasingly brought forward as a goal to reach sustainability goals of ensuring human wellbeing within the limits of Earth’s life support systems. Scholarship on the required capacities for planetary stewardship is growing rapidly, as are the insights. 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).
