Summary of "Influence of dissolved organic carbon on the acute toxicity of copper and zinc to white sturgeon (Acipenser transmontanus) and a cladoceran (Ceriodaphnia dubia)."

We conducted acute lethality tests with White Sturgeon (Acipenser transmontanus) and Ceriodaphnia dubia exposed to copper and zinc at DOC concentrations ranging from 0.5 to 5.5 mg/L. DOC had minimal effects on zinc toxicity, but DOC did have a protective effect on acute copper toxicity which was equal to that predicted by the copper BLM. BLM adjusted copper EC50s for A. transmontanus ranged from 2.4-8.2 mg/L. This article is protected by copyright. All rights reserved.

Influence of Hardness and Dissolved Organic Carbon on the Acute Toxicity of Copper to Zebrafish (Danio rerio) at Different Life Stages.

Copper (Cu) bioavailability varies under water conditions. In the present study, the whole life of zebrafish was divided into three different life stages (larvae, juvenile and adult) based on the grow...

Importance of Surface Coating on Accumulation Dynamics and Acute Toxicity of Copper Nanomaterials and Dissolved Copper to Daphnia magna.

In this study the effect of copper oxide nanomaterials (CuO NMs), uncoated and with three different surface coatings (i.e. carboxylated, pegylated and ammonia groups), was evaluated on acute toxicity ...

Assessing effects of dissolved organic carbon and water hardness on metal toxicity to Ceriodaphnia dubia using diffusive gradients in thin films (DGT).

We evaluated the ability of diffusive gradients in thin films (DGT) to assess the effects of water hardness and dissolved organic carbon (DOC consisting of humic acids) on Cu and Zn toxicity (i.e., 48...

Separation of oil sands process water organics and inorganics and examination of their acute toxicity using standard in-vitro bioassays.

Oil sands process water (OSPW) contains complex components of inorganics and organics. This is the first study that separated OSPW inorganic and organic fractions and examined their relative acute tox...

Comparison of toxicity induced by EDTA-Cu after UV/HO and UV/persulfate treatment: Species-specific and technology-dependent toxicity.

Advanced oxidation processes (AOPs) can degrade heavy metal complexes in wastewater to improve the removal efficiency of metals. However, the influences of AOP treatments on toxicity induced by metal ...

Medical and Biotech [MESH] Definitions

A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.

Unstable isotopes of copper that decay or disintegrate emitting radiation. Cu atoms with atomic weights 58-62, 64, and 66-68 are radioactive copper isotopes.

P-type ATPases which transport copper ions across membranes in prokaryotic and eukaryotic cells. They possess a conserved CYSTEINE-HISTIDINE-SERINE (CPx) amino acid motif within their transmembrane helices that functions in cation translocation and catalytic activation, and an N-terminal copper-binding CxxC motif that regulates enzyme activity. They play essential roles in intracellular copper homeostasis through regulating the uptake, efflux and storage of copper ions, and in cuproprotein biosynthesis.

Organic compounds composed exclusively of carbon and hydrogen where no carbon atoms join to form a ring structure.

Organic compounds composed exclusively of carbon and hydrogen. Three or more carbon atoms are arranged in a cyclic structure and they possess aliphatic properties.
