Symptoms of mercury vapor 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 vapor poisoning? Let's talk about it

Severe cases may cause generalized peritonitis due to gastrointestinal perforation, shock due to dehydration and other reasons, and liver damage in individual cases.

Toxic nephropathy due to necrosis of renal tubular epithelial cells, usually oral mercury salt for several hours, inhalation of high concentration of mercury vapor for 2-3 days, edema, anuria, azotemia, hyperkalemia, acidosis, uremia, until acute renal failure and life-threatening. The patients with mercury allergy may have hematuria, eosinophilia, and systemic allergic symptoms. Some patients may have acute glomerulonephritis. In severe cases, hematuria, proteinuria, hypertension and acute renal failure (ARF) may occur.

matters needing attention

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.
