Mercury If you have touched or come into contact with mercury, you should remove your shoes and clothes and put them in two sealed plastic bags. Here's the procedure for handling and cleaning up mercury in broken thermometers and other items you should know: 5.1 Preparations Before Cleanup: Keep children and pets away from the spread of germs. Mercury and inorganic mercury compounds: 8-hour mean (TWA) 0.02mg/m3 Maximum each time (STEL) 0.04mg/m3. In Vietnam, the limit of mercury in the air in the working area is regulated by the Ministry of Health as follows: Organic mercury: 8 hour average (TWA) 0.01mg/m3 Maximum each time (STEL) 0.03mg/m3. They can accumulate in the food chain and enter the human body when these foods are ingested. Mercury after evaporation will circulate in the air, soil and water, forming chemical compounds and transforming into different physical forms of mercury. mercury will be dispersed long distances, seriously affecting human health. For every 10☌ increase in temperature, the evaporation rate of mercury doubles, which is why mercury fires often have very serious consequences due to the strong evaporation of mercury, combined with wind. They will evaporate faster if in ventilated conditions. When spilled out of the container, the mercury separates into small droplets and is widely dispersed. Its vapor is colorless and odorless, so it is difficult to detect the presence of mercury in the air. Mercury is a highly volatile metal that can evaporate even at room temperature. Children with mercury poisoning have red cheeks, nose, lips, hair loss, teeth and nails, short-term rash, muscle weakness, sensitivity to light. Acute exposure to mercury vapor has been shown to cause profound central nervous system effects, including psychotic reactions characterized by delirium, hallucinations, and often euphoria. Many studies have shown that acute exposure from 4-8 hours to mercury doses from 1.1 to 44mg/m3 will lead to chest pain, shortness of breath, hemoptysis, and impaired lung function. Symptoms of mercury poisoning depend on the type, dose, manner and duration of exposure, but in general common symptoms include muscle weakness, poor coordination, numbness of hands and feet, skin rash, weakness Sensory (hearing, visual, language) In people with long-term exposure to mercury vapor (eg factory workers.) there are also tremors, cognitive impairment and sleep disturbances. , Hunter-Russell syndrome (a genetic disorder that causes disabilities in children, causing children to have average or below average intelligence, more severe causes mental retardation, bone deformities. Mercury poisoning can lead to a number of diseases such as acrodynia (pink skin disease), Minamata disease (nerve disease caused by mercury poisoning, named after the environmental disaster caused by mercury emissions in Japan). Temperatures for the gas and ice giants (Jupiter, Saturn, Uranus, and Neptune) are taken from a level in the atmosphere equal in pressure to sea level on Earth.Mercury is a less toxic metal, but its vapors, compounds and salts are extremely toxic, causing damage to the nervous system, digestive system, respiratory system, immune system and kidneys for the human body. It can be as cold as -290☏ (-179☌) on Mercury at night. Mercury rotates slowly and has a thin atmosphere, and consequently, the night-side temperature can be more than 1,000 degrees Fahrenheit lower than the day-side temperature. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface to above the melting point of lead. In general, the surface temperatures of planets decrease with increasing distance from the Sun. This graphic shows the mean temperatures of various destinations in our solar system.
