    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

  4. 4. THE ROLE OF WATER PURITY IN EMULSIFICATION AND REMOVAL OF OIL FROM SOLID SURFACES

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Andriani Tsompou; [2021]
    Keywords : ultra-pure water; detergency; detachment of oil from solid surfaces; washing; cleaning;

    Abstract : Detergents are broadly used in our everyday life for cleaning and washing procedures. They are however, a source of water pollution and can have a negative effect on human health and the environment. To reduce their negative impact, a new trend of using only pure water for washing and cleaning applications is being implemented. READ MORE

  5. 5. Blågröngrå system i kallt klimat

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Jennika Jädernäs; Erika Tjernberg; [2021]
    Keywords : Blågröngrå system; dagvattenhantering; regnbädd; skelettjord; kallt klimat; grön urban infrastruktur; klimatanpassning; ekosystemtjänster; gatugestaltning; landskapsarkitektur;

    Abstract : Det finns stora möjligheter och behov att kombinera urbaniseringens markanspråk med grön urban infrastruktur och i det arbetet säkra en hållbar dagvattenhantering. Att som landskapsarkitekt arbeta med detta är viktigt eftersom markanspråken ökar mängden hårdgjorda ytor i städer vilket samtidigt reducerar grön urban infrastruktur. READ MORE
