Publication: Evidence for specific receptor-mediated toxicity of pharmaceuticals in aquatic organisms

The toxicity of 17 active pharmaceutical ingredients (APIs) was investigated using standardized acute and chronic tests with Daphnia magna and 2 algae species. Chronic toxicity was generally greater for Daphnia than for algae. Compilation of additional data resulted in 100 APIs for which the acute-to-chronic ratio (ACR) was determined for Daphnia. The frequency of high…

New publication: Impact of an immunosuppressive human pharmaceutical on the interaction of a bacterial parasite and its invertebrate host

The interaction of pollutants and pathogens may result in altered (often enhanced) effects of the chemical, the biotic stressor or both. While standardised detection methods for immunotoxic effects of chemicals exist with regard to human health, such test systems are lacking for invertebrate species and no guidance is available on how immunotoxic effects of a […]

New publication: Prospective environmental risk assessment of mixtures in wastewater treatment plant effluents

The aquatic environment is continually exposed to a complex mixture of chemicals, with effluents of wastewater treatment plants (WWTPs) as one key source. The aim of the present study was to investigate whether environmental risk assessments addressing individual substances are sufficiently protective for such mixtures. Based on a literature review of chemicals reported to occur […]

Review of the effects of organic pesticides on enchytraeids (Oligochaeta) in agroecosystems – laboratory and higher-tier tests

Enchytraeids (Oligochaeta, Annelida) are regularly found in agroecosystems of the temperate regions of the world. Although less known than their larger relatives, the earthworms, these saprophagous organisms play similar roles in agricultural soils influencing soil structure and organic matter dynamics and having a central place in soil food webs. Due to difficulties in distinguishing the […]

New publication: Survival, reproduction, growth, and parasite resistance of aquatic organisms exposed to wastewater treated by advanced treatment processes

Advanced wastewater treatment processes are known to be an effective tool for reducing micropollutant discharge into the aquatic environment. Nevertheless, some processes such as ozonation result in stable transformation products with often unknown toxicity. In the present study, effluents from different steps of advanced treatment were compared for their aquatic toxicity. Lumbriculus variegatus, Daphnia magna […]
