Polybromerade difenyletrar (PBDE) och hexabromcyklododekan (HBCDD) är bromerade flamskyddsmedel som har använts i stor utstäckning i olika produkter under lång tid. Dessa föreningar är svårnedbrytbara och fettlösliga vilket innebär att de kan lagras länge i fettvävnaden. Både kemin och egenskaperna hos PBDE og HBCDD liknar det kända miljögiftet PCB, vilket gör at det är intressant att se närmare pPolybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCDD) are brominated flame retardants. These compounds are lipophilic, persistent and have been shown to bioaccumulate. The Baltic grey seal (Halichoerus grypus) and the Eurasian otter (Lutra lutra) are top predators and especially exposed to high levels of lipophilic pollutant in their diet due to biomagnification. In the current

Tillgång och Effektfrågan – Biogasens Roll i det Gröna Norrbotten Allt fler nyfikna ögon riktas mot Norrland i takt med att den nordligaste landsänden ångar på framåt i utvecklingen mot fossilfria industrier; kommande år planeras miljardinvesteringar i fossilfria tekniker i region Norrbotten, en satsning som kallas den gröna omställningen. Men för att kunna förse etableringarna och samhället med

Climate change is one of the most significant challenges that building sector is confronting. For example, Climate change and associated extreme events are posing a significant challenge for the building sector. Buildings should be prepared to withstand the climate changes and extreme weather that will happen in the future. Designing buildings based solely on past or average weather conditions, wh

This thesis is designed as exploratory research, with the aim of studying the relatively underexplored and poorly understood theory-practice gap in small-medium enterprises transition from sustainability ideal to practice. While existing literature has extensively addressed theoretical implications, scant attention has been paid to the lived experiences of SMEs, particularly within the context of

The carbon intensity is an important metric that provides a clear measure of the environmental impact associated with the electricity use. Carbon intensity of electricity use is differentiated into CO₂ equivalents per kilowatt-hour, which standardises the measurement by expressing the emissions of various greenhouse gases in terms of the equivalent amount of CO₂ based on their global warming poten

Literature reviews from different countries show that the difference between the calculated and measured energy use of the building, often known as “energy performance gap”, can be as high as 100-200%. Knowing the size of the building energy performance gap, if it exists, along with its underlying causes will enable professionals to make more informed assumptions and produce better predictions. As

Biologisk mångfald, varför ska vi bry oss? I nyheter och media blir vi alltmer uppmärksammade på begreppet ’biologisk mångfald’ som ofta presenteras med en negativ klang kopplad till förlust av naturmiljöer. Naturen som utgör grunden för mänsklig välfärd håller på att försvinna, bland annat på grund av mänskliga aktiviteter som urbanisering och moderna jord- och skogsbruksmetoder. Med den ökade urSpending time outdoors during childhood can improve learning, promote pro- environmental behavior, and improve physical and mental health. However, most of our everyday lives are spent indoors and thus a disassociation from nature is created. Paradoxically, a positive relationship between humans and nature is vital for its preservation, and our survival. Through outdoor education in elementary sch

In times of climate change, climate-related disaster displacement is becoming a growing issue. While the vast majority of disaster displaced people move within their country or to a neighbouring country (within a region), there are also people who move between regions and to Europe (interregional). However, there is currently no global legally binding framework that regulates the protection of the

Denna uppsats undersöker potentialen att utnyttja sex sidoströmmar/exportströmmar från den svenska livsmedelsindustrin till livsmedel för människor. Sidoströmmar som inte är industriens huvudsakliga syfte men skulle kunna bidra med näring. I dagsläget går majoriteten av strömmarna till produktion av biobränsle eller till djurfoder. En litteraturstudie genomfördes där strömmarnas avkastning, egens
