Project: microplastic@food - Development of a valid method for detecting different types of microplastics in foods

In the project microplastic@food simple food samples are analyzed for microplastic (MP) contamination starting from mineral water and beverages (fruit juices, beer, wine) through soluble food like salt and sugar until food surfaces. The participating industrial partners provide the samples from different part of the production next to the ready-to-consume product; therefore, we are also able to identify the entering points of microplastics into the food. As a scientific partner, our task is to develop sample preparation techniques which make the analyses of the microplastics possible in the different matrices. After the thorough sample preparation, the samples are analyzed by FTIR and Raman imaging techniques. Together with the industrial partners the goal is to decrease the amount of MPs in the product and at the end provide information to the decision makers about setting limits and making regulations.
In the project MicroWash we focused on analyzing fibers and especially plastic fibers originating from laundry. Many fibers are found in the wastewater stream of a large laundry, most of which are fed into the municipal wastewater treatment plants via the wastewater systems. The systems there are not designed to eliminate microparticles. The innovative flotation system is to use bubble technology to transport and separate the microfibers in the wastewater stream of the industrial laundry in a continuous process. The flotation system will be continuously submerged under water, which places special demands on the drive and the media supply. The wastewater processes of the laundries have to be adapted. To enable a quick installation, the flotation system is integrated into a process kit that can be installed as an "easy-to-fit" solution for the integration of known laundry systems. Within the project we developed an image analyzing software which helps to determine (count and measure) fibers in a simple way. The software is easy-to-use, and the sample preparation is also simple and can be used in a non-laboratory environment as well.

PhD in Chemistry:

During my PhD I worked on the removal of organic pollutants from groundwater by treatment with ferrate. In the first phase of my studies, I received samples from a highly polluted industrial area, where 44 different Volatile Organic Compounds (VOC) were detected, and the Chemical Oxygen Demand (COD) was ~4000 mg O2/L. In the second phase of my work, experiments using model solutions (containing ultrapure water, NaHCO3 and the analytes of interest) were carried out, to investigate the findings occurred during the groundwater experiments and to assess the effect of the commonly present cations (Ca2+, Mg2+, Zn2+, Ni2+) and the iron-oxy/hydroxide precipitation formed during the ferrate treatment on the removal of three different chlorobenzene (CB) compounds.
