1. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

2. Microbial production of chemical building blocks from lignin
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. LÄS MER
3. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

4. TOXICITY DRIVERS IN CHEMICAL MIXTURES FROM THE SWEDISH WEST COAST – EFFECTS ON PELAGIC COMMUNITIES
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Human society benefits from a range of ecosystem services provided by the oceans, such as oxygen production, carbon storage, and fishing. However, these services are relying on the ecosystem’s functional and structural integrity, which are correlated to its biodiversity. LÄS MER
5. 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
