One of the most common causes of toxicity in sheep is the accidental feeding of feedstuffs intended for other livestock. Molybdenum reduces the accumulation of copper in the liver. The ratio of copper to molybdenum in the feed is, therefore, an important factor determining the risk of copper ...
Farmland soil is often the recipient of combined antibiotics and heavy metals, which could greatly influence soil microbial activity and function. We chose the frequently used and widely distributed EFX and Cu, two representative chemicals that could interact in soil, to explore the toxicity of singl...

Selenium (Se) and sulfur (S) are both essential elements in wildlife and livestock, and they belong to the same family of elements that share a common uptake site in the cell wall of plant roots because of their structural similarity and have a similar affinity for the site. It has been...
Studies have highlighted the branchiae as the primary organ susceptible to Cu toxicity in fish [1]. Na+,K+-ATPase plays a vital role in maintaining ion electrochemical gradients across fish branchial plasma membranes [46]. Disruptions to the activity of this enzyme could compromise both respirator...
deficiency. This condition results from a mutation in theATP7Agene, which leads to failure of intestinal copper transport across thegastrointestinal tractand subsequent copper deficiency.55Wilson diseaseis a disorder ofcopper toxicitythat results from an impairment in biliary copper excretion (seeChapter ...
In summary, this work proposed a smart strategy for achieving an unprecedented synergism: reuse of livestock waste, recovery of heavy metal, and microbial pollution control. The cow dung-based biochar serves as a green adsorbent to recover copper ions from wastewater, and in situ reduce Cu2+ions...
This study aimed to determine the acute and chronic toxicity of Cu and its toxicological effects on respiratory metabolism, as well as Cu accumulation in C. dauricus. The acute (96 h) median lethal concentration (LC50) value of 32.5 mg/L was detected in C. dauricus. Then, acute (96 h;...
Therefore, it is of great importance to investigate toxicity mechanism of heavy metals and the adaptation mechanism of M.domestica larvae for improving the efficiency of M.domestica larval biotransformation. The heavy metals in the environment enter the insect through food intake and mainly accumulate ...
