Standard OECD tests are used to generate data on biodegradation (OECD 307) and sorption (OECD 106) of test chemicals in soil. In such tests, data on abiotic degradation using sterile samples are utilised to investigate any losses due to abiotic processes. The data from sterile samples are also used to interpret results and findings of non-sterile samples, especially in the context of sorption and non-extractable residue (NER) formation.

- The study investigates how synthetic sewage affects the microbial community in sewage treatment plants (STPs) and whether this impacts the treatment process, particularly in terms of treating gold nanoparticles (AuNPs) that may enter STPs due to their medical use.
- It utilizes a standardized STP simulation test (OECD 303A) to examine microbial diversity and degradation activity in activated sludge, focusing on dissolved organic carbon and nitrogen removal.
- Results will help determine if assessing only the functional properties of STPs is adequate, or if the microbial diversity also needs to be considered for regulatory evaluations.
The use of environmental DNA (eDNA) for monitoring aquatic macrofauna allows the non-invasive species determination and measurement of their DNA abundance and typically involves the analysis of eDNA captured from water samples. In this proof-of-concept study, we focused on the novel use of eDNA extracted from archived suspended particulate matter (SPM) for identifying fish species using metabarcoding, which benefits from the prospect of retrospective monitoring and also analysis of fish communities through time. We used archived SPM samples of the German Environmental Specimen Bank (ESB), which were collected using sedimentation traps from different riverine points in Germany.
