Microplastics (MPs) can stick to lots of different pollutants in the environment, making them important to study.
This research looked at how different types of MPs and their structures affect how they absorb these pollutants.
It found that the way a chemical sticks to MPs depends a lot on how "water-repelling" (or hydrophobic) the chemical is and how solid the MP is, with stronger effects seen for very hydrophobic chemicals.
