1. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field
Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER
2. Unraveling the importance of solid and adsorbed phase mercury speciation for methylmercury formation, evasion and bioaccumulation
Sammanfattning : Monomethylmercury, MeHg, is formed under anoxic conditions in waters, sediments and soils and then bioaccumulated and biomagnified in aquatic food webs, negatively effecting both human and wildlife health. It is generally accepted that precipitation of mercury, Hg, and adsorption of Hg to e.g. LÄS MER
3. Caring for people and the planet : preschool children’s knowledge and practices of sustainability
Sammanfattning : Children across the globe today are continuously being exposed to and affected by various kinds of real-world complexities and challenges; however, research on their knowledge and practices in terms of sustainability is limited, in particular with regards to how preschool- and home-related factors are associated with their learning for sustainability. Since 1998, different types of eco-certification have been awarded by the Swedish National Agency for Education and Keep Sweden Tidy Foundation to promote education for sustainability (EfS) in all areas of education and learning.

4. Environmental assessment of construction with recycled materials
Sammanfattning : The use of industrial residues as raw materials in construction raises concerns over the potential leaching and dispersal of hazardous constituents from them into the environment. Their leaching behaviour has been studied in laboratory assays, but leaching processes in the field over larger spatial and temporal scales are more complex due to variations in the conditions the materials are exposed to, and less well understood.

5. Fate of perfluoroalkyl acids in the aquatic environment with a focus on mass balance studies
Sammanfattning : Perfluoroalkyl substances (PFASs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer product applications, such as in aqueous film forming foam (AFFF), durable water repellent clothing, hydraulic oils and food packaging materials.
