6. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

7. Effect of Ibuprofen on the growth of Pseudokirchneriella subcapitata
Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Pharmaceuticals are an important class of pollutants in aquatic ecosystems. Detected concentration are typically in the range 1 ng/L – 1 μg/L. Traditional wastewater treatment does not provide a complete removal of these contaminants; hence, they may have a negative impact on the environment. LÄS MER
8. Cytochrome P450 expression and growth inhibition in R. subcapitata in response to pharmaceutical cocktail exposure : An ecotoxicological study of metoprolol, omeprazole, paracetamol and diclofenac
Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Pharmaceuticals and their metabolites are present in the environment, with levels expected to rise in the future. The effects on off-target organisms are still mostly unknown and of increasing concern, as are combination cocktail effects. LÄS MER
9. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. LÄS MER
10. Azithromycin effects on R. subcapitata on molecular levels : Ecotoxicological study on the effects of a pollutant on chlorophyll contents, pcna and cyt P450 genes expression
Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Antibiotics are considered a type of antimicrobial that particularly has an impact on bacteria or fungi in humans and animals. The widespread use of common antibiotics, combined with the fact that the majority of active antibiotics and their metabolites are water-soluble, results in persistent pollution in aquatic environments, as well as a potential threat to ecosystems.
