Possibilities to group micro- and nanoplastic particles:
Insights from the perspective of the BMBF project InnoMat.Life

Compared to grouping of conventional substances or nanomaterials, establishing grouping approaches for micro- and nanoscaled plastic particles (MNPs) is much more challenging. The description of the chemical composition is more complicated for polymers and these particles are inherently heterogenous in many key properties.

This talk will provide an overview on the experimental work conducted within the InnoMat.Life consortium (www.innomatlife.de) to challenge possible grouping criteria using a variety of selected MNPs including several types of polyethylene, polyamide, polyurethane, polymethyl methacrylate and a rubber material obtained from recycled truck tires. As potential grouping criteria we assessed, among others, surface reactivity and biological effects considering human and environmental model systems, transport of different environmental contaminants, sedimentation and flotation behavior as well as ageing and fragmentation rates.

Based on our current data first conclusions concerning suitable approaches and criteria for grouping of different MNPs are possible. Our work is important for developing approaches to assess risks for human health and the environment.
