Om
PhD candidate in the research group Bioanalytical Toxicology.
Plastic products consist of a great variety of chemicals that may leach and reach humans and the environment via different exposure pathways. Besides some well-known substances (bisphenols, phthalate and nonylphenols) little is known about the chemicals present in plastics. Mostly neither the chemical composition nor the toxicity of the final products is known.
Research
As part of the LimnoPlast project my aim is to characterize the in-vitro toxicity of leachates from plastic products of different polymer types with a focus on bio-based and bio-degradable polymers. With the help of effect directed analysis, I want to identify substances causing the observed in-vitro effects.
