11. Microplastics in food webs- occurrence in Lake Vänern brown trout (Salmo trutta) and its main prey
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Over the past decade, research on microplastic pollution has gained significant attention. Research regarding microplastic occurrence in freshwater fish, however is still scarce. While possible pathways have been investigated, passive transfer via ingestion of prey, and possible bioaccumulation in different organs remains relatively unstudied. LÄS MER
12. Effects of temperature and microplastic concentration on the consumption of microplastic particles by the detritivore Asellus aquaticus
Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : Microplastic (MP) pollution has now reached a point where particles can be found in every environmental compartment across the globe. However, the ecological and long-term consequences of MPs are largely unknown. LÄS MER
13. Användning av den vattenbaserade emulsionspolymeren för utveckling avspecifika egenskaper hos tegel och betong: syntes och karakterisering
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Improvement properties of building materials are essential. In this dissertation thesis, the main concern had been on synthesizing a new resin to improve the properties of concrete and brick. Solvent-based polymers have been used for many years to improve the quality of building materials. LÄS MER
14. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.

15. Distribution and transport of microplastics and metals in sewage sludge-amended agricultural soil : a Comparative study between microplastics copper, cadmium, and nickel
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : This thesis investigated the vertical transport of microplastics and metals in agricultural soil after sewage sludge application. Sewage sludge is commonly used in agriculture for adding nutrients and carbon to improve the soil quality. LÄS MER
