Factsheet 7.2: Microplastics in the aquatic food web - Impact and transfer analysis based on the example of roundworms (nematodes)

"To assess the ecologic danger posed by microplastics, one must also consider indirect effects in the food web", say Sebastian Höss (Ecossa) and Marie-Theres Rauchschwalbe (Bielefeld University). The researchers from the joint project MikroPlaTaS looked at these effects using nematodes as an example.

Factsheet 7.1: Microplastics around dams - How do plastic particles behave in reservoirs?

Plastic is now ubiquitous not only in the sea but also in many inland waters. In certain areas, such as at barrages or in dams, the flow velocity decreases. As a result, the particles previously held in suspension by the current begin to sink to the bottom of the water and can then accumulate in the sediment.

Analysis of Microplastics - Sampling, preparation and detection methods

This status paper was prepared within the framework of the cross-cutting issue 1 "Analytics and reference materials" of the research focus. It summarizes the contents of the project discussions and coordination within the cross-cutting issue. The organization of this ongoing process of development or elaboration has been supported by several events.

When Good Intentions Go Bad

The paper shows that well meant is not always well done. It deals with the question of blank value entries and how "one" should handle them. It shows that disposable gloves can be a source of false positive PE findings, as they can be coated with sterates, for example, which can be confused with PE by all analytical methods (pyr-GC/MS and spectroscopy).

Validation of Sample Preparation Methods for Microplastic Analysis in Wastewater Matrices

There is a growing interest in monitoring microplastics in the environment, corresponding to increased public concerns regarding their potential adverse effects on ecosystems. Monitoring microplastics in the environment is difficult due to the complex matrices that can prevent reliable analysis if samples are not properly prepared first.
