We are looking for a motivated PhD candidate with interest in the effects of microplastics (MP) fertilizer coatings in soil. These microplastic coatings are used to control the rate of nutrient release to the soil. Important questions are: (1) to what extent does the fertilizer coating MP accumulate in soil as compared to background levels of MP and (2) whether these MP may cause eco(toxico)logical effects for selected soil organisms and how these effects are related to polymer properties.

You will work in a joint project of the Soil Chemistry and Chemical Soil Quality Group (Prof. dr. Rob Comans and dr. Bert-Jan Groenenberg) and the Aquatic Ecology and Water Quality Management Group of Wageningen University (prof.dr. Bart Koelmans; www.microplasticlab.com ). The project will be done in cooperation with ICL specialty fertilisers.

You will develop a robust method for analysis of MP in soils using advanced IR microscopic techniques, which will be used to answer the above mentioned research questions. You will design and perform controlled laboratory experiments to investigate processes that control the fate and effects of MP in a variety of soil types and investigate samples from an already established field trial with 6 years additions of coated fertilizers
