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.
