Abstract The world‐class Alaskan Bristol Bay salmon fishery and vast deposits of copper
(Cu) and other metals in the watershed warrant further investigation into the potential toxicity …

ABSTRACT In Europe, the European Union's Existing Substances Regulation (EEC 793/93),
the REACH Regulation, and Water Framework Directive all share common guidance for …

The mitigating effect of increasing hardness on metal toxicity is reflected in water quality
criteria in the United States over the range of 25–400 mgl− 1 (as CaCO3). However, waters …

Abstract The Australian and New Zealand water quality guidelines aim to supplement and
modify existing criteria, which are mostly based on Northern Hemisphere toxicity data, with …

The acute biotic ligand model (BLM) is proposed by the US Environmental Protection
Agency (US EPA) to incorporate bioavailability in calculating aquatic life criteria for Cu in …

Although chemical risk assessment is still mainly conducted on a substance‐by‐substance
basis, organisms in the environment are typically exposed to mixtures of substances. Risk …

The influence of pH, dissolved organic carbon (DOC) concentration, water hardness, and
dissolved organic matter (DOM) source on the acute toxicity of copper were investigated with …

The US Environmental Protection Agency (EPA) and the Office of Water have made
significant changes in the approaches taken to assessing metals in the aquatic environment …

The objective of the present study was to assess the predictive capacity of the acute Cu
biotic ligand model (BLM) as applied to chronic Cu toxicity to Daphnia magna in freshwaters …

The proper application of biotic ligand models to predict metal toxicity depends on accurate
prediction of metal binding to sites on natural organic matter (NOM) which compete with the …
