Internship | Understanding formation of microplastics using various detection techniques

Exposure to micro- and nanoplastics (MNPs) can occur via various ways, for example through the use of plastic products such as reusable cups and synthetic textiles. However, reuse of products and especially the treatment between uses often leads to damage or decreases material quality. It is possible that this would lead to an increase in MNP formation and subsequent human exposure. In order to gain a better understanding of the effect of reuse on MNP formation, we need to be able to measure and detect MNPs under real-world use conditions. Your task will be to develop reproducible and realistic procedures for the simulation of plastic materials in use and to analyse the MPs that are formed this way. Use cases will be selected that have both a high risk of MNP formation and human exposure, and simulated to quantify MNP release and understand the influence of factors that may accelerate this such as clothes dryers and dishwashers.

First, a selection of the most common reusable plastic products will be made. Second, a system to simulate repeated use of the most relevant products will be designed and built in the lab. Third, MNPs produced during the (re)use of these products will be analysed with amongst others µFTIR, SEM-EDX/CL and TED-GCMS, with a special focus on the smallest fraction.

Practical:

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

Important to be aware of before applying:

• Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
  • 1) you are enrolled at the educational institution during the internship, and;
  • 2) the internship takes place as part of the programme of the study.
• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
