1. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna
University essay from Lunds universitet/Centrum för analys och syntesAbstract : 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.

2. Environmental transformation and dissolution of Cobalt- and Nickel-based Nanoparticles in Presence of Eco-corona Biomolecules
University essay from KTH/Yt- och korrosionsvetenskapAbstract : Den ökande trenden med att använda tillverkade nanopartiklar (NPs) i olika tillämpningar i samhället har väckt oro när det gäller deras växelverkan med naturliga ekosystem. Syftet med denna studie är att ta fram data under förhållanden som simulerar realistiska scenarios och syftar till att förstå växelverkan mellan koboltbaserade NPs (Co, Co3O4 och Co SCS) och nickelbaserade NPs (Ni, NiO och Ni SCS) med naturliga nedbrytningsprodukter (biomolekyler, ekokorona) som utsöndras från Daphnia magna.

3. Response of Daphnia magna from Natural Populations to Ultraviolet Radiation
University essay from Lunds universitet/Examensarbeten i biologiAbstract : Diel vertical migration (DVM) is performed by various zooplankton taxa. The general movement pattern of DVM has been well studied while the possible clonal differences of this movement largely remain unknown. My master thesis focus on investigating the effects of environmental stressors on Daphnia magna strains isolated from natural populations. READ MORE

4. (Toxic) effects induced by synthetic and natural microparticles on Daphnia magna : Investigating particles and mixtures
University essay from Stockholms universitet/Institutionen för miljövetenskap och analytisk kemiAbstract : With increasing global plastics production, the amounts of fragmenting, microscopic plastic debris (microplastics, MPs) are anticipated to rise in aquatic environments. The ecological consequences of this pollution are currently unknown. READ MORE

5. A comparison between the effects of polylactic acid and polystyrene microplastics on Daphnia magna
University essay from Stockholms universitet/Institutionen för miljövetenskap och analytisk kemiAbstract : The effects of microplastics on zooplankton are an increasing environmental concern. Both primary microplastics that are produced as constituents of cosmetic products, as well as secondary microplastics that are formed by degradation of larger plastic debris, are ubiquitous in aquatic environments.
