  1. 16. Microplastics in the Gulf of Bothnia, SwedenA comparison between Österfjärden and Örefjärden.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Emma Overgaard; [2021]
    Keywords : IR; Microplastic; pollution; polymer composition; surface water; visual characterization;

    Abstract : Microplastics are emerging pollutants in the marine environment, including a range of polymers modified by varying quantities of additives and sorbed pollutants, differing in size, colour, and shape. This study focuses on characterization and quantification through visual characterization of microplastics >300 μm in surface water and at 5-meter depth in the Gulf of Bothnia. READ MORE

  3. 17. Evaluating the potential of microplastics and natural organic matter for sorption of hydrophobic organic contaminants based on selected properties

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Sabrina Noël Reaume Zabalgoitia; [2021]
    Keywords : microplastics; natural organic matter; particulate organic matter; sorption; vector;

    Abstract : Interest in microplastic behaviour as vectors for hydrophobic organic pollutants has increased in the literature over recent years, however these materials constitute only one of many organic particulate groups in the environment able to compete for pollutants. This review examines particle characteristics including size, surface area, porosity, and age, and how these may influence natural organic particle and microplastic sorption capacity. READ MORE

  4. 18. Banning Plastic Straw by Straw: Why California needs a more harmonized approach to plastics management

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Rachel Adell; [2020]
    Keywords : Social Sciences;

    Abstract : Over 150 local communities in California have implemented plastic product bans as a way to decrease stress on landfills, reduce non-recyclable materials, and manage litter. Plastic product bans such as plastic bags, polystyrene, or single-use plastics, are used to address both local (e.g. litter reduction or community aesthetics), and global (e. READ MORE

  5. 19. Characterization of microplastics in wastewater

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Lina Sabienski; [2020]
    Keywords : ATR-FTIR spectroscopy; Microplastic; Plastic pollution; Visual characterization; Wastewater effluent; Wastewater treatment plant WWTP ;

    Abstract : This study aims to detect how many microplastics and what kind are released from the wastewater treatment plant (WWTP) Skebäck, in Örebro. The study was limited to the analysis of three filters with 50 μm mesh size and one filter with 300 μm mesh size. READ MORE
