The Wasser 2022 conference brought together German water chemistry professionals to discuss topics including microplastics, new pollutants, and groundwater contamination, with one presented study identifying 15 persistent mobile organic compounds in German groundwater using a novel freeze-drying enrichment screening approach.
The "Wasser 2022" conference, organized by the German Water Chemistry Society, is the central annual meeting for professionals in water chemistry. Held online due to pandemic conditions, it covered key topics such as water quality, new pollutants, wastewater treatment, analytical methods, groundwater, sediments, microbiology, hygiene, nanoparticles, microplastics, and drinking water. The event brought together experts from water chemistry and related fields to share the latest research, discuss current challenges, and foster meaningful professional dialogue within the water sector. TALK This work presents a robust "Screen Smart" strategy for identifying highly mobile chemicals in groundwater. The newly developed freeze-drying enrichment—with an enlarged frozen sample surface—enabled sensitive suspect screening and efficient sample processing. By focusing on carefully selected wells and tiered suspect lists, the study identified 15 persistent and mobile organic compounds, including several previously unknown in German groundwater. The approach streamlines monitoring, reduces analytical effort, and highlights the need for further investigation of PMOCs that pose health risks and are largely unregulated.

Adsorption of Heavy Metal with Aged Microplastic in Groundwater Under Varying Organic Matter Content
AI summary Read the abstract
Researchers examined how aged microplastics in groundwater adsorb heavy metals at varying levels of organic matter, finding that microplastics can act as carriers for toxic metals. This means microplastics in drinking water sources may carry additional chemical hazards beyond the plastic particles themselves.
