Original Title: Scientists have extracted microplastics from the sand of 22 beaches in New Zealand. Almost all of the particles were smaller than a dust mite (<300 μm). However the study could only detect particles larger than a human skin cell (32 μm), so there's likely even more plastic in the sand.
