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.

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...
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 ...
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...
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...
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 ...
Assessment of the impact of oral Human Milk Oligosaccharides (HMO) application on acute diarrhoea and the development of prolonged and persistent diarrhoea in paediatric patients hospitali...
OBJECTIVES: Primary Objectives • Determine the safety and toxicity profile of co-administration of disulfiram and copper gluconate for the treatment of refractory malignancies th...
The purpose of this study is to determine the safety and optimal dosing of intravenous copper chloride and disulfiram in men with metastatic castrate-resistant prostate cancer (CRPC). Elig...
The purpose of this study is to compare delayed vs. immediate insertion of the Copper T 380 IUD after termination of pregnancy after 12 weeks.
Copper is an essential nutrient for humans and is cofactor in enzymes that participate in critical body functions. Insufficient copper can lead to hematological and neurological abnormali...
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.
