Does mercury evaporate and how long does it take for mercury to evaporate cleanly

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.

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.

Mercury volatilizes at room temperature.

Here's how to do it.

Because mercury is easy to volatilize and be inhaled by the human body posture to cause poisoning, it is necessary to deal with the mercury meter in time and correctly after it is broken.

Clause. 1. Quickly remove children and pets from the room, and remember not to use vacuum cleaners, brooms, or rags to clean mercury.

Clause. 2. Clean up the mercury while keeping the room ventilated, if the room can adjust the temperature and reduce the room temperature as much as possible, it can reduce the volatilization of mercury and promote condensation. If the mercury falls on the smooth ground such as tiles, you can use cardboard shells, celery sheets, scrapers, etc., from the periphery of the scattered parts close to the ground to scrape to the center, you can see that the mercury balls will gradually gather into large balls, and then gently shovel up the mercury balls and close them into a plastic bag.

If mercury is scattered on rough surfaces such as carpets or on beds, you can tape them and then close them with tape into a plastic bag, which is recommended to be layered in layers to prevent breakage and leakage. Dark areas or very small particles of mercury can be found with a flashlight, as mercury can reflect light.

Thirdly, after the mercury is collected, some sulfur can be sprinkled and buried deep underground.

Mercury will volatilize, and mercury is the only metal in a liquid state at room temperature and pressure. This unique physical property of mercury metal makes it volatile, in a zero air environment, let the mercury evaporate, the concentration can reach milligrams per cubic meter, more than 100 times more than the occupational health standard, and with the increase of indoor temperature, the volatile capacity of mercury will also increase simultaneously.

If it is indoors, it usually takes about a few hours to get clean. However, during this period, it is necessary to open windows for ventilation to maintain indoor air circulation. If the mercury in the thermometer is coming out, it needs to be gathered together with toilet paper, then put into a paper shell or plastic bag, and covered with sand before it can be thrown into the trash.

Applications:The most common applications for mercury are in the manufacture of industrial chemicals and in electronic or electrical products. Sakura mercury is also used in thermometers, especially in thermometers that measure high temperatures.

More and more gaseous mercury is still used in the manufacture of fluorescent lamps, while many other applications have been phased out due to health and safety concerns, replaced by the less toxic but much more expensive Galinstan Dust. In addition to this, mercury is used in the following ways:

Gold is often used in gold mines because it decomposes gold from its minerals.

It is used to make instruments such as barometers and diffusion pumps.

Gaseous mercury is used in mercury vapor lamps.

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.
