The biotic ligand model (BLM) is a mechanistic approach that greatly improves our ability to
generate site-specific ambient water quality criteria (AWQC) for metals in the natural …

The bioaccumulation and toxicity of heavy metals were reviewed with special reference to
microalgae, the key component of the food web in aquatic ecosystems. Heavy metals enter …

Toxicities of ZnO, TiO2 and CuO nanoparticles to Pseudokirchneriella subcapitata were
determined using OECD 201 algal growth inhibition test taking in account potential shading …

This is the first study investigating the toxicity of nanoparticles (NPs) to algae in the presence
of dissolved organic matter (DOM). Suwannee river fulvic acid (SRFA), a type of DOM, could …

Environmental context Natural organic matter exerts a powerful control on chemical
conditions in waters and soils, affecting pH and influencing the biological availability …

EPA recognized that metals present unique risk assessment issues, and saw the need to
develop a framework document that puts forth key scientific principles for metals risk …

Since the early 2000s, biotic ligand models and related constructs have been a dominant
paradigm for risk assessment of aqueous metals in the environment. We critically review 1) …

Copper (Cu) exists in a variety of forms in different aquatic environments, and affects their
bioavailability. In this study we provide a systematic review on toxicity of Cu which focuses …

The influence of pH (6.0–9.0), natural organic matter (NOM)(0–10 mg C/L) and ionic strength
(IS)(1.7–40 mM) on 14 nm CeO2 NP aggregation and ecotoxicity towards the alga …

Copper and zinc toxicity to the freshwater alga Chlorella sp. was determined at a range of
pH values (5.5–8.0) in a synthetic softwater (hardness 40–48 mg CaCO 3/L). The effects of …
