Description Microplastic (MP) (1 µm – 5 mm) are emerging pollutant due to their ubiquitous occurrence and persistence in the environment, as well as their toxicity to living beings. Polymer-coated fertilizer (PCF) consists of a soluble mineral fertilizer core surrounded by a layer of polymer coating (polyurethane, polyester, alkyd, etc.). PCF is a source of primary MP in soil that has gained more attention due to a recent proposal of restriction on intentionally added MP in products from European Chemical Agency (ECHA). Although soil is recognized as a major sink of MP, there were limited studies on MP in soil compare to other environmental compartment partly due to the lack of a standardized and reliable analytical method. The thesis aim is to develop and testing microplastic extraction method from soil, with the focus on PCF-derived MP.
Used skills - Literature review to understand and develop microplastic extraction method from soil, as well as targeted PCF-derived MP
- Laboratory work to validate the extraction method with appropriate analysis techniques (Microscope/Fourier-transformed Infrared/Nile-red dye)
- Laboratory work to refine extraction method where possible
- Data processing and writing
Requirements Required courses for MSc thesis Soil Chemistry and Chemical Soil Quality. Good laboratory skills. Keen interest to work with microplastic.
