The smaller plastic particles are, the more easily they can be taken up by cells. In addition, the shape, surface and chemical properties play an important role in answering the question of how the particles could affect human tissue. This conclusion is the result of a study by researchers at the German Federal Institute for Risk Assessment (BfR), published in the journal Microplastics and Nanoplastics.
