Traineeship in Mixture toxicity assessment of metal-based nanoparticles to Lettuce

This autumn (2014), students are needed who want to do a traineeship in Nanotoxicology.

Scope

Engineered metal‐based nanoparticles (NPs) have been used in ever more products, which in their final life phase likely end up in the aquatic and terrestrial environment. It is thus that their potential adverse effects to the ecosystems are increasing and the risk assessment for them are urgently needed. However, current environmental risk assessment is inadequate for metal-based NPs perhaps due to their unique characteristics such as a relatively large surface area and high reactivity which lead to a different behavior from dissolved metal species and sub‐micron‐sized particles.

Project

The student project is on mixture experiments of metal‐based nanoparticles using lettuce as a test‐organism. Root elongation will be the assessed endpoint. We consider the importance of fate and behavior of the metal‐based nanoparticles in exposure medium. To quantify that we do various chemical and physical measurements besides the eco‐physiological measurements. We are searching for a MSc‐ or BSc‐student who is able to do his/her traineeship in our group. The student place can be offered directly from now on.
