Symptoms of mercury poisoning?
summary
Mercury is a silver white liquid metal, which evaporates at room temperature. Chronic mercury poisoning is the most common, mainly occurs in production activities, long-term inhalation of mercury vapor and mercury compound dust. The main symptoms were mental nerve abnormality, gingivitis and tremor. Acute mercury poisoning occurs when a large dose of mercury vapor is inhaled or mercury compounds are ingested. For those who are allergic to mercury, even if they are topically coated with mercury oil matrix preparation, poisoning can also occur. Symptoms of mercury poisoning? Let's talk about it.
Symptoms of mercury poisoning?
(1) General symptoms: metallic taste in the mouth, headache, dizziness, nausea, vomiting, abdominal pain, diarrhea, fatigue, general soreness, shivering, fever (38-39 ℃), and in severe cases, emotional agitation, restlessness, insomnia, even convulsion, coma or mental disorder.

Oral poisoning can cause abdominal pain, diarrhea, mucus discharge or bloody stool. Severe cases may cause generalized peritonitis due to gastrointestinal perforation, shock due to dehydration and other reasons, and liver damage in individual cases.
matters needing attention
1. Replace mercury with non-toxic or low toxic raw materials, such as electronic instruments instead of mercury meters and alcohol thermometers instead of metal mercury thermometers. 2. When smelting or pouring mercury, exhaust hood or closed device should be set to avoid mercury vapor escaping, and mercury concentration in the air of workshop should be measured regularly. The surface of the wall, floor and operation platform of mercury workshop should be smooth without cracks, so as to facilitate cleaning and detoxification. The temperature of workshop should not exceed 15 ~ 16 ℃. The maximum allowable concentration of mercury in the air of the workshop is set at 0.001 mg / m3. 3. Workers exposed to mercury should have physical examination once a year to find out patients with mercury absorption and early mercury poisoning in time for early treatment. Mercury containing waste gas, waste water and waste residue should be discharged after treatment. 4. The way to deal with mercury leakage is: if there is still liquid, sulfur powder should be sprinkled on it to make it react; If it has volatilized, pay attention to indoor ventilation, and do not touch mercury directly with hands to avoid skin allergy.
