6. TROFISK ÖVERFÖRING OCH TOXISKA EFFEKTER AV (NANO-)PARTIKLAR FRÅN ELEKTRONISKT AVFALL
Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Today, nanoparticles (NPs) are being included in an increasing number of products, and with that comes the dispersion of NPs in the environment. However, the ecological impact of NPs remains largely unexplored, particularly in regards to real emissions with complex compositions of NPs and other pollutants. LÄS MER
7. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER
8. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments
Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

9. Stadsträd – i nöd och lust : skillnader i reglerande och stödjande ekosystemtjänster mellan löv- och barrträd i stadsmiljö
Kandidat-uppsats, SLU/Dept. of Urban and Rural DevelopmentSammanfattning : Träd har en viktig roll i att klimatanpassa städer genom att leverera ekosystemtjänster. I nordiska städer planteras mest lövträd eftersom det historiskt funnits ett kulturellt motstånd mot barrträd. LÄS MER
10. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. LÄS MER
