TL;DR: Care needs to be taken in toxicity testing in ascribing toxicity to nanoparticles per se when the effects may be related, at least in part, to simple solubility, as this study has shown.

TL;DR: The nature and extent of the transformations that occur in nanomaterials must be understood before significant progress can be made toward understanding the environmental risks posed by these materials.

TL;DR: This journal issue includes papers that describe recent advances with regard to the development of the biotic ligand model and represents a distinct milestone in the ongoing evolution of the BLM approach and, more generally, of approaches to performing ecological assessments for metals in aquatic systems.

TL;DR: In this article, the effects of short-term resuspension of a contaminated anoxic estuarine sediment on solid-phase metal speciation have been studied and preliminary experiments investigated the oxidation rates of model metal sulfide phases to provide mechanistic information for interpreting the observations on the natural sediment.

TL;DR: Findings suggest that standard static laboratory bioassays using 104 to 105 algal cells/ml may seriously underestimate metal toxicity in natural waters.
