Food products can become contaminated with nanoplastics and microplastics (NMP) at any stage of the manufacturing process due to the ubiquitous use of plastics materials and wide-spread environmental contamination.
While knowledge about dietary exposure to NMPs has grown over the last decade, there is still little data on NMP contamination on a range of commonly consumed foods, with most studies focusing on marine organisms and counting particles in the micro-range (typically >10-20 µm). Furthermore, there are no standardised methods for measuring NMP contamination and more research is needed to determine the most reliable methods to capture data required to inform human health risk assessments.
This project aims to investigate dietary exposure to NMPs in the Australian population, and evaluate the utility of a range NMP extraction and analysis techniques in food matrices.
