From non-target screening to risk assessment

Non-target screening, bioassays and computer modelling can provide information about the structure, concentration and toxicity of unknown substances in water. Until now, these chemical, biological and computing methods have often been used…

Effect-based monitoring of water quality in the circular economy

Freshwater from groundwater or surface water sources is becoming scarce in dry periods, driving a rise in interest in the use/re-use of rainwater and treated domestic and industrial…

Toxicology on Target

The domain of toxicological risk assessment is constantly evolving and it is essential to follow these developments closely. It has been noted that an adequate response to water quality issues requires the ongoing development of knowledge and…

Are PMOCs less toxic?

Persistent mobile organic compounds (PMOC) accumulate in the water cycle and are hardly removed during water treatment. For a long time, these substances have been under-researched but recent studies show that they are present in worrying concentrations.…

Nanoplastics in drinking water

It is becoming increasingly clear that plastic is everywhere. That has been demonstrated in numerous environmental compartments, including soil, sediment, surface water and air. Data about the presence of microplastic particles in surface water are sparse, and…

Water-soluble polymers – Eyes and ears for Chemical Safety 2019-2020

Water-soluble polymers are often neglected because they are not covered by the definition of microplastics and are not visible. As a result, very little is still known about…

Clearer picture of the formation of transformation products during drinking water treatment thanks to integrated strategies

During drinking water production, biotic and antibiotic processes can form transformation products (TP) from organic micropollutants (OMP). How these substances behave in water treatment and how toxic they…

Improved prioritisation and fragmentation improve the identification of unknown substances with non-target screening

Non-target screening (NTS) is based on the combination of liquid chromatography in conjunction with high-resolution mass spectrometry (HRMS). In addition, tailored data analysis, with target and suspect screening,…

Trigger value data gaps I and II

There are a lot of advantages to testing water quality with in vitro bioassays but this technique can only be properly applied if the bioassay responses can be compared with ‘effect-based trigger values’ (EBT). This study determines…
