Acute and chronic toxicity studies were conducted on Daphnia pulex using synthetic lead
and arsenic water samples. For acute studies, solutions with 0.25, 0.5, 1.0, 2.0, 5.0 mg/L …

Standardized toxicity tests are generally performed with juvenile test organisms, eg, in
Daphnia magna assays neonates< 24h old are used. The purpose of this research was to …

Water quality standards for copper are usually stated in total element concentrations. It is
known, however, that a major part of the copper can be bound in complexes that are …

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 …

Effective detoxification of oil sands process-affected water (OSPW) is one issue associated
with bitumen extraction in the Alberta oil sands. It has been suggested that reclamation …

The extended free ion activity model (FIAM) was developed by integrating concepts from the
original FIAM into biological receptor theory, to obtain a conceptual model that more …

Numerous studies have suggested that the toxicity of organic compounds containing at least
one carboxylic acid group and broadly classified as “naphthenic acids”, is of environmental …

Many freshwater habitats around the world suffered dramatic water chemistry changes over
the last century mostly due to anthropogenic activities, including an overall reduction in pH …

It is well known that chemical parameters, such as natural organic matter (NOM), cation
content and pH may influence speciation and toxicity of metals in freshwaters. Advanced …

A number of risk assessments of the adverse effects of Cu and its compounds have been
conducted since it is one of the leading substances responsible for water contamination …
