What happens when copper exceeds the standard in the human body?
Copper (Cu) is an indispensable element for the human body. The adult human body generally contains 70-100 mg of copper, with an average content of 1.4-2.1 mg per kilogram of body weight. Copper is present in all organs and tissues of the body, usually bound to proteins or other organic matter. Among them, the liver is the warehouse for storing copper, which has a high copper content, and the brain and heart are also more. So it seems that the lack of copper in the human body is definitely not enough, so is the more the better? An element that makes people both happy and afraid: heavy metal copper, although it is one of the indispensable elements for the human body, once it is missing, it will be harmful to the body. But one more thing to remember is that if the copper in the body exceeds the standard value, it will be harmful to the human body, so the more the better! Copper is also an essential component of several brain amino acid oxidases. Copper deficiency will cause the activity of amine oxidase in the body tissue to decrease, resulting in the impairment of elastin and collagen synthesis. When copper is deficient, the activity of copper protein is weakened, which limits the utilization of iron in ferritin and causes anemia. Fetal development, bone growth, red and white blood cell development, iron transport and absorption, cholesterol and glucose metabolism, normal heart muscle movement, brain development, etc., are all inseparable from the participation of copper. The lack of copper in pregnant women can lead to increased tissue fragility, thinning of the amniotic membrane and reduction of its elasticity, premature rupture of the membranes, retardation of fetal bone development, weight loss, and even miscarriage, premature delivery, and fetal neural tube. defect. Pregnant women also need copper for good health and normal body functions. Copper deficiency can cause many clinical symptoms, including anemia, heart and circulatory problems, and bone deformities. The above briefly introduces the consequences of copper deficiency, so what happens if copper exceeds the standard? The following manufacturers of online water quality monitors come to learn about what will happen if the copper in the water exceeds the standard! In water bodies, excess copper will pollute water bodies and cause stress and harm to aquatic animals and plants. Copper can affect the growth of animals and plants in the water, and it will also be enriched in the sediment in the water. When the bottom mud is stirred by external force, the copper deposited in it will be released into the water body again and become endogenous pollution. At the same time, copper can also enter the human body through the enrichment of the biological chain, and then cause harm to the human body. As for how to avoid drinking copper-contaminated water sources, it is necessary to install water quality online monitoring equipment at major sites to monitor the copper content in water in real time, and compare the water environment standards to determine whether the water source is polluted. The instrument used to detect copper in water is called: total copper online analyzer. by optical colorimetry. After the pretreated water sample is injected into the reaction tank by a syringe pump, it first reacts with a strong acid reagent to uniformly oxidize all forms of copper in the water sample into divalent copper ions, and then add a reducing reagent to reduce the divalent copper ions Reduce to cuprous ions, then add masking agent to interfere with coexisting ions in the water sample, add characteristic chromogenic agent for color reaction, within the measurement range, the degree of color change is proportional to the concentration of copper in water, by measuring the degree of color change , the copper content in the water sample can be calculated.
