TL;DR: This review assesses the current literature on the occurrence of environmentally released micro- and nanoplastics in the human food production chain and their potential health impact and discusses the potential use of the very sensitive analytical techniques developed for the detection and quantification of engineered nanoparticles.

TL;DR: Oral exposure toSilver nanoparticles appears to be very similar to exposure to silver salts, however, the consequences of in vivo formation of silver nanoparticles, and of the long retention of silver in brain and testis should be considered in a risk assessment ofsilver nanoparticles.

TL;DR: This study uniquely describes all steps of the risk assessment process for the use of one specific nanomaterial (nanosilica) in food products and identifies gaps in essential knowledge and the difficulties and uncertainties associated with each of these steps.

TL;DR: The number-based size distributions for TiO2 particles in the food and personal care products showed that 5-10% of the particles in these products had sizes below 100 nm, comparable to that found in the E171 materials.

TL;DR: The findings suggest that, upon consumption of foods containing E551, the gut epithelium is most likely exposed to nano-sized silica, even in amounts higher than in the saliva (mouth) digestion stage.
