2. Open all windows and use electric fans to enhance indoor and outdoor air circulation.
3. Turn off indoor heating equipment and other air conditioning systems.
4. Use eye drops, syringes, bookmarks, business cards, plastic sheets, wet cotton swabs or tape paper to collect.
5. The collected mercury should be stored in a sealed and sturdy container, and the bottle cap should be sealed with adhesive tape and marked as "waste mercury"; Articles (such as clothes, carpets, etc.) ) must also be placed in a sealed container.
6. For mercury that falls to the ground and cannot be completely collected, you can sprinkle some sulfur powder to clean it up, because sulfur and mercury (mercury) will react chemically to generate non-toxic mercury sulfide, which will not affect your health if inhaled, and liquid mercury will not volatilize into the air in large quantities to cause harm to the human body.
Extended data:
The harm of mercury to human health is related to its chemical form, environmental conditions and ways of invading human body. Metal mercury vapor is highly diffusive and fat-soluble, which can be completely absorbed by alveoli after invading respiratory tract and transported to the whole body through blood.
Metal mercury in blood can enter brain tissue through blood-brain barrier, and then be oxidized into mercury ions in brain tissue. Because it is difficult for mercury ions to return to the blood through the blood-brain barrier, they gradually accumulate in brain tissue and damage brain tissue.
Metal mercury in other tissues may also be oxidized to ionic state and transferred to the kidney for accumulation.
The clinical manifestations of chronic metal mercury poisoning are mainly nervous system symptoms, including headache, dizziness, numbness and pain in limbs, muscle tremor and dyskinesia.
Inhaling a large amount of mercury vapor will cause acute mercury poisoning, and its symptoms are hepatitis, nephritis, proteinuria, hematuria and uremia. Acute poisoning is common in production environment, but rare in general living environment. The amount of metallic mercury absorbed by digestive tract is very small.
Metal mercury ingested through food and drinking water generally does not cause poisoning.
Inorganic mercury compounds can be divided into soluble and insoluble. Insoluble inorganic mercury compounds are easy to precipitate in water.
Although insoluble mercury compounds suspended in water can enter the gastrointestinal tract through people, they are difficult to be absorbed and will not cause harm to people. The absorption rate of soluble mercury compounds in gastrointestinal tract is also very low.
Methylmercury enters the human body mainly through food, and is easily absorbed in the human intestine and transported to various organs of the whole body, especially the liver and kidneys, of which only 15% reaches the brain tissue.
However, methylmercury first damages the brain tissue, mainly the cerebral cortex and cerebellum, so it has clinical manifestations such as centripetal vision loss, dyskinesia, acrosensory disturbance and so on.
This is different from the tremor caused by the invasion of metallic mercury into brain tissue. The brain damage caused by methylmercury is irreversible, so far there is no effective treatment, which often leads to death or lifelong illness (see Minamata disease).
