TL;DR: A weak non-significant increasing trend was noted between mean cladoceran 48-h EC(50) and ambient copper concentration of the different aquatic systems, suggesting acclimation/adaptation in the field.

TL;DR: Standard culture media, some of which may be deficient in copper, can result in sub-optimal performance of the organisms, which in turn may affect toxicity test results, and an optimal concentration range was established for copper for this algal species.

TL;DR: A field study was conducted to validate concentrations of zinc in freshwater sediments that are tolerated by benthic macroinvertebrate communities and to determine whether a relationship exists with the acid volatile sulfide-simultaneously extracted metal (AVS) model.

TL;DR: The environmental relevance of using toxicity data obtained with organisms (natural, as well as laboratory clones) acclimated to culture media containing no or very small amounts of zinc can be questioned.

TL;DR: A biotic ligand model (BLM) was developed in which the effects of Ca and Mg were modeled as single-site competition effects and was able to accurately predict earlier published 48-h EC50s for another D. magna clone as well as for Ceriodaphnia dubia.
