Microplastic contamination has been a much-discussed topic over the last several years, but contamination from even smaller plastic particles represents another pressing issue. Nanoplastics—defined as being under a micrometer in diameter—may pose an even higher ecological risk because they can travel more easily, cross cellular membranes and easily adsorb other pollutants.
Although nanoplastics have been found in environments all over the world, it was thought that soil in pristine places like Antarctica, particularly areas farther from the ocean, might be somewhat protected from contamination. However, a new study, published in Scientific Reports, reports that nanoplastics have now been found in the soils of desert valleys in the interior of Antarctica.
