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

2. Snow quality in urban areas
Sammanfattning : The studies reported on this thesis aim to provide information and increase knowledge about the quality of urban snow and the path of pollutants. The results develop a basis for decisions regarding the prevention of environmental damage. LÄS MER
3. Melting of urban snow deposits : a water quality study

4. Sources and fluxes of organic contaminants in urban runoff
Sammanfattning : Urban runoff quality is recognized as one of the most significant pressures on aquatic ecosystems worldwide. Research into pollutants in urban runoff has traditionally focused on nutrients, suspended solids and metals and consequently knowledge of anthropogenic organic pollutants is limited. LÄS MER
