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.
TL;DR: Long-term exposure of aquatic organisms to nTiO(2) may alter the growing status of these organisms at both individual and population levels, posing risks to aquatic ecosystems.
TL;DR: Evidence is provided of the relationship between chemical composition and toxicity of plastic/rubber leachates, which ranged from slightly to highly toxic to mussels and algae, highlighting the need for a better understanding of the overall impact of plastic-associated chemicals on aquatic ecosystems.
TL;DR: In this paper, the authors used OECD standard methods on some ionic liquids and found that they have very high toxicity towards freshwater algae and the freshwater invertebrate Daphnia magna (∼104−106 times more ecotoxic than methanol for the worse cases).
TL;DR: An improved model to calculate toxicity potentials: the global nested multi-media fate, exposure and effects model USES-LCA, based on the Uniform System for the Evaluation of Substances 2.0 is outlined.
