Microplastics: A trojan horse for metals

Read the full story from the Helmholtz Association of German Research Centres.

The fact that microplastics can accumulate organic pollutants from the environment and transport them has been known for some time. What is new, however, is that metals can also be transported in this manner. In addition, the smaller the particles, the greater the metal accumulation on the plastic. This has been demonstrated by scientists at the Helmholtz-Zentrum Hereon in a new study. The results were published in the Journal of Hazardous Materials Letters.
