  1. 6. 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

  3. 7. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

    Författare :Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

    Sammanfattning : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. LÄS MER

  4. 8. Microbiome Of Ecotoxicity Assays

    Författare :Asa Motiei; Elena Gorokhova; Natàlia Corcoll; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biofilm; Microplastics; Suspended solids; Aquatic toxicology; Daphnia magna; Ecotoxicology; Bacterial colonization; Particle aggregation; Microbiome interaction; Standardization; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Microorganisms are ubiquitous and present in animal microbiomes, particulates, and colonizable surfaces of test systems. From an ecotoxicological perspective, they are metabolically active biological compartments that respond to test conditions, including test substances. LÄS MER

  5. 9. Occurrence of Traffic-Derived Microplastics in Different Matrices in the Road Environment

    Författare :Ida Järlskog; Yvonne Andersson-Sköld; Stephan Wagner; Statens väg- och transportforskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-exhaust particles; tire wear particles; road dust; automated SEM EDX; environmental samples; optimized sample preparation; organic pollutants; street sweeping; traffic-derived microplastics; road simulator;

    Sammanfattning : The prevalence of microplastic contamination has raised concerns about the potential risk and impact on the global environment. Traffic-derived microplastics, i.e., tire wear particles (TWP), polymer-modified bitumen, and road markings contribute to the emissions, and TWP are assumed to be one of the largest sources of microplastic emissions.

  7. 10. Mitigating Microplastics Pollution in Urban Water Systems : Flow, actors, and control measures

    Författare :Emma Fältström; Stefan Anderberg; Annica Carlsson; Hamse Kjerstadius; Lian Lundy; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Municipalities; Plastic; Pollutants; Preventive measures; Stormwater; Wastewater; Water treatment;

    Sammanfattning : Water pollution has long been considered a challenge in urban areas. Urban wastewater and stormwater act as transport pathways for pollutants from urban areas to receiving waters. Microplastics are a pollution problem of growing concern. LÄS MER
