What are the effects of inhaling small amounts of mercury vapor on humans?

Mercury, commonly known as mercury, is the only known liquid metal, which becomes liquid at room temperature, and can also be volatilized at room temperature, and is a heavy metal, heavy metal ions are harmful to the body, but mercury monons are toxic to the central nervous system of the human body after inhalation. Nerves are susceptible to toxicity after inhalation, symptoms of neurotoxicity may occur, and a small number may cause dizziness. Headaches, confusion in large quantities, mania, deep intoxication will cause death.

When the mercury hits the ground, take it up with paper, put it in a bottle, add some water to the bottle, and close the lid, preferably in a jar. The volatilization of mercury vapor will be reduced, and after volatilization, the vapor will be partially dissolved in water, and the frosted mouth of the jar will also reduce the amount of volatilization, and the amount of inhalation by the human body will be reduced. Oh.

You shouldn't have a problem with this. The amount you inhale is almost negligible. Generally, if the amount is large, it mainly causes infertility and infertility.

Mercury, scientific name mercury, is a toxic silvery-white heavy metal element, among all kinds of metals, mercury has the lowest melting point, only and the only metal that is liquid and easy to flow at room temperature, and the texture is like freezing. Its chemical symbol ** is Latin and originally means "liquid silver". It is mainly used for scientific instruments and mercury boilers, mercury pumps and mercury gas lamps.

Once the items containing mercury are broken, the mercury will form a sphere and roll off, forming very fine particles that adhere to walls, clothing, and floors. If left untreated, it will persist for years or even decades to come, and slowly evaporate without special temperature changes. Although inhaling mercury in small amounts does not cause much harm to the body, long-term inhalation of large amounts can cause mercury poisoning.

Patients with acute mercury vapor poisoning have a rapid onset of illness, and may have fever, cough, dyspnea, nausea, vomiting, chest tightness, salivation or tearing. Further, diarrhea and psychoneurological symptoms may occur, such as mental disorders, incoherent speech, alternating wakefulness and coma. Mild cases can last for a week or more, while severe cases can usually die in a coma within a few hours.

Chronic poisoning can cause excitability, irritability, lack of concentration, followed by mood and personality changes, and even hallucinations. It can also be accompanied by generalized tremors, mouth ulcers, gingivitis, loose teeth, loss of teeth and other manifestations of stomatitis.

Mercury poisoning is more common in chronic, mainly occurs in production activities, long-term inhalation of mercury vapor and mercury compound dust, generally acute poisoning, symptoms mostly appear after 2-3 days, these symptoms do compound, but it may also be irreversible damage caused by the first poisoning, mercury is mainly excreted in urine and feces, saliva, milk, sweat is also excreted in a small amount, it is not completely impossible, if, blood mercury is also low, it means that you really discharge better, it is best to compare before and after, good, It is best to check blood mercury if you can't check it, then recheck it again, mercury poisoning itself has many harms

You shouldn't have a problem with this. The amount you inhale is almost negligible. Generally, if the amount is large, it mainly causes infertility and infertility.

There should be no problem, as the amount is very small.

Mercury can be volatilized at room temperature, which is easy to cause pollution, and its ways are: Accidental operation causes mercury to splash out, seep into the floor, table cracks, etc., which is not easy to eliminate and become a long-term source of pollution; When the prefabricated capsule is opened, the mercury vapor is easy to overflow due to the high temperature; There is an overflow of mercury vapor during the removal of a filling and the development and filling process.

Self-protection must be done by: keeping the office well ventilated; Regularly test the mercury content in the air, which should not exceed 50m3; Conduct regular urine tests for staff; Residual mercury can be stored in a closed fixer or water; Avoid direct contact with amalgam, especially mercury, and wash the contact area with soap and water after contact; The method of dealing with splashed mercury droplets: you can use a suction bottle, or you can use a rubber blanket or a fresh mercury from the investigation to eliminate fine mercury droplets, and you can sprinkle sulfur powder in an inaccessible place to form a covering film on the surface to prevent mercury from evaporating.

This paragraph] is allergic to mercury contact.

The toxic effects of mercury on humans have been widely reported and have attracted widespread attention from the medical community. A number of mercury-related allergic reactions have been reported in recent years. For example, redness, swelling, blisters, ulcers, and white lesions may appear in the mouth; Hyperemia, red rash, itching, swelling, and a positive patch test may appear on **.

Such patients should not come into contact with amalgam fillings, and if contact allergies are confirmed, they should immediately switch to other fillings.

The amount is very small, and it should be fine.

Entering the body from the respiratory tract.

Mercury poisoning is more common in chronicity, mainly occurring in production activities, caused by long-term inhalation of mercury vapor and mercury compound dust. Psycho-neurological abnormalities, gingivitis, and tremor are the main symptoms. Acute mercury poisoning occurs when high doses of mercury are inhaled or mercury compounds are ingested.

In people who are allergic to mercury, poisoning can occur even if a mercury oil matrix is applied topically. Workers exposed to mercury are mercury mining, amalgam smelting, gold and silver extraction, mercury rectifiers, as well as production workers of vacuum pumps, lights, meters, thermometers, amalgam fillings, mine mercury, pigments, pharmaceuticals, nuclear reactor coolants, and materials protected against atomic radiation. In the past, organic mercury compounds were mainly used as agricultural fungicides, but they were highly toxic and were no longer produced and used in China.

Pathogenesis: Mercury vapor easily penetrates the lipid-containing cell membrane of the alveolar wall, binds to lipids in the blood, and is quickly distributed to all tissues throughout the body. Mercury is oxidized to Hg2+ in red blood cells and other tissues, where it accumulates in combination with proteins and is difficult to release. Metallic mercury is almost not absorbed in the gastrointestinal tract, only about 1/10,000 of the ingestion amount, and the absorption of mercury salts in the digestive tract is about 10.

Mercury is mainly excreted in urine and feces, but also in small amounts in saliva, breast milk, sweat, and exhaled in the lungs. The half-life period of mercury in the body is 60 days, and the mercury salt is about 40 days, and the amount excreted in the first 4 days is larger.

Mercury ions are easy to bind to sulfhydryl groups, which inactivate cytochrome oxidase, pyruvate kinase, succinate dehydrogenase, etc. related to sulfhydryl groups. Mercury also binds to amino, carboxy, and phosphoryl groups to affect the activity of functional groups. As the activity of these enzymes and functional groups is affected, the biological activity and normal metabolism of the cell are hindered, which ultimately leads to cell degeneration and necrosis.

In recent years, it has been found that mercury can damage the kidney, mainly in the proximal convoluted tubule epithelial cells of the kidney. Mercury can also cause immune dysfunction, autoantibody production, nephrotic syndrome, or glomerulonephritis.

Sulfur powder is used for absorption, which can form a very stable mercury sulfide, and if it is steam, it is absorbed by iodine vapor.

Mercury is a chemical element, commonly known as mercury (mercury can also be written as 龾).Its chemical symbol is Hg, and its atomic number is 80It is a heavy, silvery-white liquid transition metal. Because of this property, mercury is used to make thermometers.

Pure mercury is toxic, but its compounds and salts are very toxic and can cause brain and liver damage when taken orally, inhaled, or after exposure. As a result, most of today's thermometers use alcohol instead of mercury. Some medical thermometers still use mercury because of its high accuracy.

At standard air pressure and temperature, the biggest danger of pure mercury is that it is easily oxidized to produce mercury oxide, which tends to form small particles and increase its surface surface balance.

Although pure mercury is less toxic than its compounds, it is still a dangerous pollutant because it forms organic compounds in living organisms.

The most dangerous mercury organic compound is C2H6HG, which can be lethal when exposed to just a few microliters.

Mercury is a poison that can accumulate in living organisms, and it is easily absorbed by the respiratory and digestive tracts. Minamata disease is a type of mercury poisoning. Mercury damages central nervous system tissue, which has adverse effects on the mouth, mucous membranes, and teeth.

Prolonged exposure to high mercury can lead to brain damage and death. Despite the high boiling point of mercury, the saturated mercury vapor at room temperature has reached several times the toxic meter.

Therefore, special care should be taken when handling mercury. Containers containing mercury should be particularly protected from spillage or evaporation, and heating of mercury must be carried out under a well-ventilated and well-filtered hood. In addition, some mercury compounds are automatically reduced to pure mercury, which evaporates and is often overlooked.

There is nothing wrong with that.

The respiratory absorption effect is likely to be no more than 1 in 10,000. In daily life, the so-called mercury vapor that you can come into contact with is most likely a thermometer Just like that, rest assured that there is no problem.

As for real poisoning, the best way is naturally hemodialysis. But if it's light, it's likely that you're just waiting for your body to get rid of it.
