If mercury is spilled on the ground and cleaned up, is it possible for chronic poisoning after three days of ventilation?

The mercury thermometer is a very practical tool, but it is also a dangerous thing for expectant mothers and babies. Once broken, the volatile mercury is likely to affect health. Although the mercury thermometer contains a small amount of mercury and has been processed, you still need to pay attention to its changes to avoid actual poisoning. ?

It is also unwise to wipe with a rag or take off the mop, because using objects to wipe off the mercury will accelerate the evaporation of mercury and increase its contact with the air, making it evaporate faster. Although many times the human body will not have obvious symptoms after inhaling part of mercury vapor, mercury will accumulate in the human body, forming chronic mercury poisoning. ?

The correct way to deal with mercury

If there is a heating device, turn off the heating as soon as possible, because mercury will evaporate faster at high temperatures. Then open doors and windows as soon as possible for ventilation. Reduce the concentration of mercury vapor in the environment. Then wear a mask and gloves, collect the mercury on the ground through cardboard pieces, etc. into a sealed container, such as a mineral water bottle, but remember not to touch the mercury directly with your skin, and then stick the mineral water bottle containing mercury on labels and warnings and take it to your local waste manager for disposal. ?

Mercury, the chemical name is mercury (Hg). Among the huge metal family, mercury is the only metal that is liquid at room temperature. Mercury has the lowest melting point, only -38.87°C, a specific gravity of 13.595, and a vapor specific gravity of 6.9. Mercury can easily evaporate into the air and cause harm. ?

Mercury vapor is highly toxic. It does not react with dilute sulfuric acid, hydrochloric acid, or alkali. It can be dissolved in nitric acid and hot concentrated sulfuric acid, but it can dissolve many metals. Mercury has strong sulfur affinity and cuprophilicity, which means that under normal temperature conditions, it can easily react with sulfur and copper elements to form stable compounds. Therefore, sulfur is generally used in laboratories to treat the mercury spilled on the ground. mercury. Of course, you can also use a copper wire to remove mercury scattered on the ground.

The specific method is to use a copper wire and dip it into small mercury beads that have fallen on the ground. The small mercury beads are easily stained on the copper wire. Mercury is generally resistant to copper, aluminum and other metals that are more active than mercury. It has a wetting effect, which means that metals such as copper and aluminum can be dissolved in mercury. Therefore, when the copper wire comes into contact with mercury, the mercury will adhere to the copper wire. Next, you can immerse the copper wire in water and shake off the mercury with a little force. Repeat this step and continue to collect the remaining small mercury beads until the mercury is completely collected.
