Mercury itself is not a gas, but it can produce toxic vapors when heated or when it is in a gaseous form, known as elemental mercury vapor. Prolonged exposure to mercury vapor can lead to serious health issues, including neurological damage. Additionally, mercury can form compounds with other elements, some of which may release toxic gases. It's important to handle mercury with care to avoid inhalation of these harmful vapors.
Most thermometers used to contain Mercury until it was found to be toxic.
Mercury and most of its compounds are extremely toxic. In cases of spills involving mercury (such as from thermometers) specific cleaning procedures are used to avoid toxic exposure. Mercury can be inhaled and absorbed through the skin and mucous membranes, so containers of mercury are securely sealed to avoid spills and evaporation. Heating of mercury, or compounds of mercury that may decompose when heated, is always carried out with adequate ventilation in order to avoid exposure to mercury vapor. The most toxic forms of mercury are its organic compounds, such as methylmercury. However, inorganic compounds, such as cinnabar are also highly toxic by ingestion or inhalation of the dust. Mercury can cause both chronic and acute poisoning.
