elavhõbe

Elavhõbe, also known by its chemical symbol Hg, is a chemical element with atomic number 80. It is a heavy, silvery-white metal that is liquid at room temperature, a property unique among metals. This unusual characteristic has led to its historical use in various applications, including thermometers, barometers, and electrical switches. Elavhõbe is a relatively rare element found in cinnabar ore.

Despite its utility, elavhõbe is highly toxic. Exposure can occur through inhalation of vapors, ingestion, or skin absorption. It can accumulate in the body, particularly in the brain, kidneys, and liver. Chronic exposure can lead to serious health problems, including neurological damage, kidney dysfunction, and developmental issues in children.

Due to its toxicity, the use of elavhõbe has been significantly restricted in many countries. Regulations aim to phase out its use in products like batteries, fluorescent lamps, and certain medical devices. Proper handling and disposal of elavhõbe-containing items are crucial to prevent environmental contamination and protect public health. Elavhõbe pollution is a global concern, as it can enter the food chain, particularly through fish consumption. International agreements are in place to manage and reduce elavhõbe emissions and releases.
