Short summary
The adverse effect of microplastic (MP) on soil biota and soil structure depends on MP particle size and surface characteristics. Since weathering plays a major role in the genesis of these, it must be considered in both the analysis of environmental MP and the production of artificial MP for laboratory experiments. This work integrates recent findings on adverse effects and the genesis of its surface characteristics and discusses how to reproduce them to obtain closer-to-nature designer MP.
