Mercury poisoning
Mercury poisoning
Mercury poisoning (pronunciation: /ˈmɝːkjʊri ˈpɔɪzənɪŋ/) is a type of metal poisoning due to exposure to mercury.
Etymology
The term "mercury poisoning" is derived from the chemical element mercury (from the Latin Hydrargyrum, meaning 'liquid silver') and the English word "poisoning", which refers to the harmful effects of a substance on the body.
Symptoms
Symptoms depend on the type of mercury exposure. They may include tremors, insomnia, memory loss, neuromuscular effects, headaches, and cognitive and motor dysfunction. Mild, subclinical signs of central nervous system toxicity can be seen in workers exposed to an elemental mercury level in the air of 20 μg/m^3 or more for several years.
Causes
Mercury poisoning can occur as a result of occupational hazard or suicide attempt. People can be exposed to mercury in the workplace by inhaling mercury vapors during the processing of amalgam material. Mercury poisoning can also occur as a result of consuming contaminated fish or shellfish.
Treatment
Treatment for mercury poisoning includes removal from the source of exposure and chelation therapy. The type of chelation therapy used depends on the type of mercury exposure.
