  1. 1. Chemical Pollutants Released to the Marine Environment by Degradation of Plastic Debris

    Författare :Berit Gewert; Matthew MacLeod; Magnus Breitholtz; Merle Plassmann; Martin Wagner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plastic; microplastic; degradation; leachates; weathering; photo-oxidation; marine environment; toxicity; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Since the beginning of the mass production in the 1940s, plastic has been manufactured in quickly increasing amounts. Plastic debris accumulates in the environment and lately much attention has been drawn to the pollution in the world’s oceans. LÄS MER

  3. 2. Microplastic Mitigation in Urban Stormwater : Assessing Horizontal-Flow Filters of Bark, Biochar and Sand as Remediation Strategies

    Författare :Gabriella Rullander; Sahar S. Dalahmeh; Roger Herbert; Jes Vollertsen; Claudia Lorenz; Ann-Margret Strömvall; Giuliano Di Baldassarre; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Decentralized water treatment; Filtration; Filter systems; Pollution control; Porous media; Stormwater management; Sustainable solutions; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Sammanfattning : Urban stormwater has been suggested as a significant vector through which microplastics (MPs) reach aquatic environments. Currently, only a small fraction of stormwater in Sweden undergoes any form of treatment. LÄS MER

  4. 3. Microplastics in the urban environment : Concentrations and composition in stormwater sediments and UV-degradation of common litter

    Författare :Lisa Öborn; Helene Österlund; Maria Viklander; Mats Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microplastic; stormwater; sediment; VA-teknik; Urban Water Engineering;

    Sammanfattning : Microplastics (MPs) are small pieces of plastic material including tyre wear particles (TWPs) smaller than 5000 µm. One of the primary pathways through which MPs including TWPs enter aquatic and marine environments is stormwater runoff from urban areas. LÄS MER

  5. 4. Metal and microplastic treatment in stormwater bioretention

    Författare :Katharina Lange; Helene Österlund; Elodie Passeport; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : Metals and microplastic particles are common stormwater pollutants, which can be harmful when released to the environment. The aim of this thesis is to increase the understanding of the treatment of metals and their different fractions, as well as microplastic, in bioretention systems. LÄS MER

  7. 5. Towards the Control of Microplastic Pollution in Urban Waters

    Författare :Emma Fältström; Stefan Anderberg; Sara Gustafsson; Hans Bertil Wittgren; Marinette Hagman; Sverker Molander; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Water pollution has long been considered a challenge in urban areas, and new types of pollution are continuously introduced to society. Urban wastewater and stormwater act as transport pathways of pollution from urban areas to receiving waterways. LÄS MER
