Ranking of potential hazards from engineered nanoparticles and micro/nano-plastics in food systems

Key Points

The aim is to rank the dietary risks posed by engineered nanoparticles in food systems.
Developed a probability-impact framework to assess dietary risks.
Integrated factors such as production, exposure, persistence, and toxicity using probabilistic scoring.
Identified priority nanoparticles including Ag, TiO2, ZnO, CNTs, CeO2, and CuO.
PEC and production are the most sensitive drivers of the risk ranking.
Framework identified the highest-priority nanoparticles for further regulation and testing.
Supports targeted monitoring priorities for better food safety.

Abstract

• Novel probability–impact framework ranked dietary risks from engineered nanoparticles. • Production, exposure, persistence and toxicity integrated using probabilistic scoring. • Ag, TiO 2 , ZnO, CNTs, CeO 2 , and CuO identified as highest-priority nanoparticles. • PEC and production are the most sensitive drivers influencing nanoparticle risk ranking. • Framework supports regulatory screening, monitoring priorities and targeted testing.
