This study demonstrates that commonly used consumer products such as single-use food grade nylon bags and hot beverage cups lined with low-density polyethylene release nanometer-sized plastic particles at number densities >1012 L-1 when exposed to water. The number of particles released was a function of the initial water temperature (high temperature vs ambient) for each of the tested materials. Mean particle diameters were between 30 and 80 nm with few particles >200 nm. The number of…

Beyond microplastics - investigation on health impacts of submicron and nanoplastic particles after oral uptake in vitro
The continuously increasing use of plastics is supposed to result in a rising exposure of MNPs to humans. Available data on human health risks of microplastics after oral uptake increased immensely

Plastic Teabags Release Billions of Microparticles and Nanoparticles into Tea.
TLDR
It is shown that steeping a single plastic teabag at brewing temperature (95 °C) releases approximately 11.6 billion microplastics and 3.1 billion nanoplastics into a single cup of the beverage.
Health impacts of environmental contamination of micro- and nanoplastics: a review
TLDR
It is concluded that more studies are necessary to provide a comprehensive understanding of MNP pollution hazards and also provide a basis for the subsequent pollution management and control.
Microplastic release from the degradation of polypropylene feeding bottles during infant formula preparation
TLDR
It is demonstrated that infant exposure to microplastics is higher than previously recognized due to the prevalence of polypropylene-based products in formula preparation, highlighting an urgent need to assess whether MPs exposure at these levels pose a risk to infant health.
Uptake, Whole-Body Distribution, and Depuration of Nanoplastics by the Scallop Pecten maximus at Environmentally Realistic Concentrations.
TLDR
P pulse exposures of 14C-radiolabeled nanopolystyrene to a commercially important mollusk at what have been predicted to be environmentally relevant concentrations are presented, finding that particle size apparently influenced the biokinetics and suggests a need for chronic exposure studies.
The why and how of micro(nano)plastic research
Neurotoxic effects of the oxidative thermal degradation products form low density polyethylene
TLDR
Adult male Wistar rats were exposed for 2–5 weeks, 6 h nightly, 5 nights a week to oxidative thermal degradation products of low density polyethylene derived by heating (325°C) under an airstream in a tube oven to study the neurochemical effects of exposure to potentially harmful molecules in the brain.
Determination of migrants in and migration from nylon food packaging.
TLDR
A method was developed to determine the amount of residual oligomers in nylon food packaging and oligomers that migrate to a food-stimulating liquid (oil) during oven cooking conditions, which represented 43% of the total amount of oligomers present in the packaging material.
