Aquatic ecotoxicity of pharmaceuticals including the assessment of combination effects.
TL;DR: The measured toxicities of the tested pharmaceuticals shows that acute effect of single substances in the aquatic environment are very unlikely, but it should be kept in mind that considerable combination effects can occur and that toxicity data from chronic studies are needed to assess the environmental risk of drug residues.
Journal ArticleDOI
Mixture toxicity of the anti-inflammatory drugs diclofenac, ibuprofen, naproxen, and acetylsalicylic acid
TL;DR: The ecotoxicity of the nonsteroidal anti-inflammatory drugs (NSAIDs) diclofenac, ibuprofen, naproxen, and acetylsalicylic acid has been evaluated using acute Daphnia and algal tests and could be accurately predicted using the concept of concentration addition.
Journal ArticleDOI
Initial risk assessment for three β-blockers found in the aquatic environment
TL;DR: Mixture toxicity of the three compounds could be predicted accurately using the concept of concentration addition, which means that the differences in the EC50 depend mainly on the diverse logP levels causing narcosis via disruption of membrane integrity.
Journal ArticleDOI
Life-strategy shift by intraspecific interaction in Daphnia magna : change in reproduction from quantity to quality.
TL;DR: It is suggested that for the F0 generation the ecological significance of the LiSSII effects is an increase in both the parent and offspring survival probability when food is limited, and under favourable environmental conditions, F2 daphnids that are the offspring of mothers affected byLiSSII appeared well adapted to fast recolonisation when living at low density.
Journal ArticleDOI
Phytotoxicity of coloured substances: is Lemna Duckweed an alternative to the algal growth inhibition test?
Michael Cleuvers,Hans-Toni Ratte +1 more
TL;DR: Lemna tests are recommended to be used in addition to algal tests, because doing so may significantly improve the assessment of phytotoxicity of chemicals and sewage.
