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

27. On national technology policy in global energy transitions: The case of Swedish marine energy
Sammanfattning : Mitigating climate change and achieving sustainable development requires a rapid global transition to a low-carbon energy system. Policymakers therefore promote new renewable energy technologies, while also aiming to create localized environmental and socioeconomic benefits. LÄS MER
28. Enabling socio-technical transitions – electric vehicles and high voltage electricity grids as focal points of low emission futures
Sammanfattning : Today humankind is facing numerous sustainability challenges that require us to question CO2 intensive practices like those present in the transport and energy sector. To meet those challenges, many countries have adopted ambitious climate targets. Achieving such targets requires an understanding of the wider socio-technical context of transitions. LÄS MER
