Will the watermark endanger life? That is to say, if a few watermarks of a thermometer are accidentally broken indoors, what harm will it do to the body and will be powerful to life?
Mercury vapor is very toxic. After the mercury thermometer is accidentally broken, the mercury will disperse into beads when it falls to the ground. If it is not collected and cleaned in time, it will quickly evaporate into the air and enter the nervous system through the human respiratory tract, causing poisoning symptoms.
if you accidentally touch the skin, it can enter the body, which is even more harmful to your health. Mercury can damage the brain, and may even damage the reproductive system and cause deformed offspring.
1) Clinical manifestations of mercury poisoning:
1. The general symptoms are headache, dizziness, fatigue and fever.
2. The symptoms of oral cavity and digestive tract are gingival swelling and pain, erosion and bleeding, loose teeth, pus overflowing from gingival sulcus, foul smell in oral cavity, nausea, vomiting, loss of appetite, abdominal pain and diarrhea.
3. The skin symptoms are red maculopapules, which are mainly distributed on limbs, head and face.
A few patients may have renal damage, and some severe patients may have symptoms of acute interstitial pneumonia such as cough, chest pain, dyspnea and cyanosis.
2) Collection and treatment method of spilled mercury:
1. Gently stick the spilled mercury on the ground with a small wet cotton swab or tape paper and put it into a small bottle that can be sealed. Such as plastic bottles such as beverage bottles, and a small amount of water is added to the bottles to seal them, and the bottles are marked with signs such as "waste mercury", which are handed over to the waste liquid management personnel of the unit or community neighborhood committees for treatment or sent to the environmental protection department for special treatment. (Pay attention to good ventilation in the environment).
2. Never pour the collected mercury into the sewer to avoid polluting the underground water source. If mercury seeps into groundwater and people drink water containing heavy metals, it will be harmful to human health.
3. For the mercury that falls on the ground and cannot be collected completely, sulfur powder can be sprinkled to reduce the toxicity of mercury. Because the combination of sulfur powder and mercury can form mercury sulfide compounds that are difficult to volatilize, it can prevent mercury from volatilizing into the air and endangering human health. Mildly absorbed, you can drink mung bean soup.
4. If you accidentally swallow mercury, rinse your mouth with cold water immediately, then take raw egg white or milk, and use protein to slow down the body's absorption of mercury, and then go to a doctor for treatment.
