In the project µrban Plastics, which is funded by the Swedish Environmental Protection Agency, we have received extra support from Jonathan Svedin, who during the spring term 2020 is doing his master thesis work in one of the sub-projects.
Jonathan is a student at the civil engineering program Natural resource engineering, and examines in his thesis how different types of ordinary plastic debris are broken down under UV light. The purpose is to gain knowledge about how debris affects the spread of microplastics via stormwater to watercourses, lakes and the sea.
The study is carried out in a laboratory environment and five types of plastic have been selected and exposed under UV lamps to accelerate aging and degradation. After 1-8 weeks of exposure, samples are sent for analysis to see how much microplastic has formed and in what size fractions they are present.
We look forward to Jonathan's report and presentation at the end of the semester - keep your eyes and ears open! Heléne Österlund supervises the thesis work and Annelie Hedström is the examiner.
