The increased use of silver nanomaterials presents a risk to aquatic systems due to the high
toxicity of silver. The stability, dissolution rates and toxicity of citrate-and polyvinylpyrrolidone …

The use of sediment quality guidelines to predict the toxicity of metals in sediments is limited
by an inadequate understanding of exposure pathways and by poor causal links between …

Acid-volatile sulfides (AVS) are an important metal-binding phase in sediments. For
sediments that contain an excess of AVS over simultaneously extracted metal (SEM) …

Many regulatory frameworks for sediment quality assessment include consideration of
contaminant bioavailability. However, the “snap-shots” of metal bioavailability provided by …

The increasing diversity and complexity of contaminants released in the environment
continuously lead to new challenges when applying ecotoxicity assays. This paper …

Sediments in navigation‐dominated waterways frequently are contaminated with a variety of
particle‐associated pollutants and are subject to frequent short‐term resuspension events …

To evaluate the risks of metal mixture effects to natural stream communities under
ecologically relevant conditions, the authors conducted 30‐d tests with benthic …

A major weakness of sediment quality guidelines (SQGs) is their poor ability to predict how
toxicity thresholds change for different sediment types. Using species sensitivity distributions …

Environmental context Aluminium may be released into coastal waters in dissolved and
particulate forms from urban runoff, industrial discharges and acid sulfate soils. Aquatic …

The discharge of acid drainage from the farm irrigation areas to the Murray River in South
Australia represents a potential risk to water quality. The drainage waters have low pH (2.9 …
