The field study compared sediment characteristics as well as multitrophic diversity and function in two vertical layers of migrating ripples and stationary patches in sandy lowland streams. It indicates that migrating bedforms create streambed heterogeneity by modulating the abundance, diversity, and structure of different trophic guilds of microbial communities and their resource acquisition.

This study investigated how organic micropollutants and the algal toxins prymnesins interact as mixtures in water extracts from the Oder River using neurotoxic effects on human nerve cells in vitro. The authors showed that prymnesins dominate the neurotoxic effects, but many of the detected organic micropollutants exacerbate the lethal effect of prymnesins.

This study investigated the formation of reactive species during the activation of the chemical oxidant persulfate with biochar and iron in different water types for the removal of organic contaminants. The presence of organic matter and chloride altered the reactive species formed, emphasizing that the water matrix is a critical factor for the application of this oxidation process .
