This is a generic term for extremely small plastic particles in the environment, produced by further digestive and other breakdown of microplastics to produce even smaller particles on the nanometre scale, which because of their extremely small size are able to penetrate to the lowest levels of the food chain (even intracellular). Also as a consequence of their extremely small size, these particles have a significantly higher surface area to volume ratio than even microplastics do, and consequently adsorption of environmental toxins by such particles is potentially far greater.
