How long does it take for mercury to volatilize and how long does it take for mercury to volatilize?

Mercury compounds are automatically reduced to pure mercury, while mercury evaporates, which is often overlooked. 】

If a device containing mercury breaks, never touch it. All personnel and pets should be evacuated immediately and the site should be well ventilated. Never heat or burn mercury. If the shoes may have been glued.

Mercury, please don't run around. Clothes and shoes that are sticky to mercury may shake it off and cause secondary pollution. Do not vacuum or broom to clean up spilled mercury. Vacuuming or cleaning mercury with a broom will increase the area of mercury contamination.

When the mercury is dispersed in the crevices or very fine, an appropriate amount of sulfur powder can be taken to cover it, so that it can produce a chemical reaction to form mercury sulfide, and it is cleaned after 3-4 hours, and the mercury sulfide is solid and cannot evaporate, so it reduces the harm to the human body; Or spray with 20% ferric chloride (10% bleach solution), at this time the mercury flowing out forms an alloy of non-toxic mercury and iron, which is placed for 1 hour and then cleaned.

The ceiling, walls, and air of the contaminated room are fumigated with heated iodine (grams per square meter or 1 gram per cubic meter), or dispersed on the ground with grams of iodine per cubic meter for 8-12 hours, while the doors and windows are sealed, and the indoor personnel exit. After treatment, ventilation should be carried out before entering to reduce the inhalation of residual mercury vapor.

Look again, the amount is less and the volatile oxidation after 3 days of ventilation is about the same.

It's about milliliters per minute, which is very small, and some of it will be absorbed by the floor. Although mercury remains for a long time, there is no problem with more ventilation. There are a lot of heavy metals and organic matter in the surrounding living environment, as long as you pay attention to stay away from pollutants.

Just don't be mentally stressed.

The thermometer is broken and gathers into a drop of mercury to volatilize naturally, and it takes a long time, at least 2 weeks

Mercury (mercury) is a liquid at room temperature and can volatilize in air, but the rate of evaporation is very slow.

At room temperature of 20 degrees Celsius, only a little bit of mercury (a bead of mercury) evaporates off after two and a half months (the weight of mercury drops from grams to grams). It should be noted that the volatilization rate of mercury is fast in the early stage and slow in the later stage.

The landlord needs to note that mercury is a metal with very little volatility and can hardly be seen for a period of time.

Mercury is the only metal that is liquid at room temperature, and when the products containing it are broken, the mercury evaporates. The rate of evaporation is very fast.

Moreover, it has particularly good adsorption. Mercury vapor is easily adsorbed by walls and clothing, and becomes a source of continuous air pollution. Although it will not cause much harm to the body if inhaled in small amounts, it can cause mercury poisoning if inhaled in large amounts for a long time.

There are two types of mercury poisoning: acute poisoning: acute poisoning has symptoms such as abdominal pain, diarrhea, and hematuria; Chronic poisoning is mainly manifested by oral inflammation, muscle tremors and mental disorders. In our daily lives, there are quite a few items related to mercury.

For example, mercury is found in all types of fluorescent lamps; Some thermos are coated with mercury on the outer walls to reduce heat radiation; Early mirrors were painted with mercury on the back; Electronics such as computer monitors also contain a certain amount of mercury; Mercury oxide is also used as the anode of the battery, if not used for a long time, the acid, alkali and other corrosive substances contained in the battery will damage the outer wall, resulting in mercury leakage Remind everyone that if the above items are accidentally broken, you must be careful when handling them, and do not mix them with other garbage and dump them. Mercury can enter water bodies, soils, pass through the food chain, and eventually harm human health. Once broken, the mercury will form a sphere and roll off.

At this time, you should first turn off all heating devices in the room and open the windows for ventilation; Then wear gloves, use a small shovel to collect the mercury and bury it deeply, or sprinkle some sulfur powder on it, sulfur and mercury reaction can produce mercury sulfide that is not easily soluble in water, and the harm will be greatly reduced. Since mercury can evaporate into a gaseous state at room temperature, it can easily be inhaled into the respiratory tract and cause poisoning, so it is best to wear a mask when handling mercury scattered on the ground.

This is closely related to the ambient temperature. The ambient temperature is high, and the volatilization is faster. It is also related to the size of the mercury beads. If a large mercury bead is dispersed into multiple small mercury beads, the surface area will increase and the evaporation will be faster. Generally, it can be volatilized clean in a week.

It's hard to say, let's deal with it at the top.

Mercury volatilizes in 1 month. When the thermometer is broken, it will form a small ball in the shape of water beads, because there is too little mercury in a thermometer to cause harm to the human body, so let the mercury volatilize as soon as possible. Open more windows for ventilation, keep the indoor air fresh and circulating, and the temperature and humidity should be appropriate.

Because the specific gravity of mercury is relatively high, then there may be small mercury beads on the ground, in this case, you can take a paper cup to collect the mercury beads, and then pour some water to avoid the evaporation of mercury and reduce its harmfulness.

It takes about 72 hours for mercury to evaporate.

Mercury is a liquid metal, it is volatile in the air, generally speaking, the mercury contained in household thermometers, if dropped on the ground, without treatment, it takes about 72 hours to evaporate. Mercury is the common name of the chemical element mercury, which has the characteristics of low viscosity and easy flow, and is a liquid metal that can evaporate at room temperature.

If mercury falls to the ground and ruptures, the corresponding volatilization time has a great relationship with room temperature and air circulation velocity. The higher the room temperature, the stronger the air flow, the faster the corresponding evaporation, and there is no specific time limit to refer to Youyanding. It is important to note that the patient should be treated promptly.

How to dispose of mercury falling to the ground

If you accidentally break the mercury thermometer in your life, you should open the window for ventilation, which can alleviate the harm caused by the volatilization of mercury in the air to the human body. It is also important to properly dispose of mercury spilled in the living environment, and when handling mercury, you should wear protective gloves. At the same time, you can use some paper towels or some gauze to carefully wrap the mercury.

In addition, the collected mercury should not be poured directly into the sewer, and it is recommended to put the collected mercury in the hazardous garbage ** bin. After the collection is completed, some sulfur powder can be sprinkled on the ground where the mercury is scattered to reduce the toxicity of the mercury that cannot be completely collected on the ground.

Mercury can evaporate at room temperature, and its vapors and compounds are often highly toxic (chronic). On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) published a preliminary list of carcinogens, and mercury and inorganic mercury compounds were included in the list of three types of carcinogens. [2] On July 23, 2019, mercury and mercury compounds were included in the list of toxic and harmful water pollutants (the first batch).

Mercury. It is volatile, and the main component of mercury is metallic mercury. Mercury is a metal, but it can be in a liquid state under normal temperature and pressure, so mercury is easy to volatilize, and when the indoor temperature exceeds 0, mercury will volatilize.

If mercury is allowed to volatilize, then in a closed environment, the concentration of mercury can reach milligrams per cubic meter, which will pose great harm to the human body, and the higher the temperature, the faster the volatilization.

Mercury volatilizes into the air and easily passes through the respiratory system.

It enters the body and causes mercury poisoning.

Therefore, in daily life and work, mercury must be sealed and sealed to avoid volatilization. Mercury is relatively volatile, and if it is indoors, it generally takes about a few hours to recover. However, during this period, it is necessary to open windows for ventilation to maintain indoor air circulation.

If it's a thermometer.

The mercury in it needs to be gathered together with toilet paper, then packed into a paper shell or plastic bag, and covered with sand before it can be thrown into the trash. A small amount of mercury volatilization generally does not cause much damage to the body, so don't worry too much.
