  2. 1. Microplastics in the aquatic environment: Insights into biological fate and effects in fish

    Author : Giedrė Ašmonaitė; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microplastics; nanoplastics; plastic pollution; effects; fish; chemical mixtures; ecotoxicology;

    Abstract : According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. It has been predicted that up to 12 million tons of plastic waste reach the aquatic environment annually. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt

    Author : Arya Vijayan; Maria Viklander; Helene Österlund; Göran Blomqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban snow; Traffic pollution; Suspended solids; Metals; PAHs; Tire and Road wear Particles T RWPs ; Microplastics MPs ; Size fractionation; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.

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

    Author : Gabriella Rullander; Sahar S. Dalahmeh; Roger Herbert; Jes Vollertsen; Claudia Lorenz; Ann-Margret Strömvall; Giuliano Di Baldassarre; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Quality of snow deposited in urban areas : Storage, load assessment and release of selected pollutants with snowmelt

    Author : Arya Vijayan; Maria Viklander; Helene Österlund; Jiri Marsalek; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Abstract : Snow deposited in urban areas is exposed to pollutants originating from traffic, wet and dry atmospheric deposition, de-icing chemicals and traction materials. The conventional pollutants found in urban snow include solids (TSS), metals (Zn, Cu, Cd, Pb, etc.), Polycyclic Aromatic Hydrocarbons (PAHs), and chlorides. READ MORE
