Is Mercury Poisoning That Rare?

What is Mercury?

Mercury is a shiny chemical element that stands out as a liquid metal. While fascinating, it poses serious health risks when ingested or inhaled in harmful amounts.


Mercury Through History

In the Middle Ages, mercury had surprising uses:

  • Medicine: It was used to treat diseases like syphilis and leprosy, often with disastrous side effects.
  • Pottery Glaze: Wealthy Europeans enjoyed beautifully glazed pottery, unaware that the heavy metals in the glaze—including mercury—were slowly poisoning them.

Today, Western countries enforce strict regulations to minimize mercury in food and consumer products. But mercury poisoning still happens.


How Do People Get Mercury Poisoning Today?

Even with regulations, mercury exposure can occur through:

  • Eating Too Much Fish: Excessive consumption of mercury-rich fish like tuna can lead to toxicity. (Pop star Robbie Williams reportedly suffered mercury poisoning from eating large amounts of tuna.)
  • Tooth Fillings: Dental amalgams may release small amounts of mercury vapour over time.
  • Polluted Areas: Living in regions with mercury-rich soil or water, naturally or from industrial pollution.
  • Novelty Jewelry: Some jewellery contains mercury as part of its design.
  • Machinery and Electronics: Certain equipment can release mercury if damaged or improperly handled.
  • Poor Ventilation: Working or living in enclosed spaces where mercury exposure increases risk.
  • Consumer Products: A few items still contain mercury, such as thermometers, batteries, or skin-lightening creams.

Symptoms of Mercury Poisoning

Mercury poisoning can manifest with both physical and mental symptoms, including:

  • Mental Health: Anxiety, depression, irritability, memory problems, pathologic shyness
  • Neurological Effects: Tremors, muscle twitching, numbness, sensory disturbances
  • Physical Weakness: General weakness and fatigue

What To Do if You Suspect Mercury Poisoning

If you think you may have mercury poisoning, see your doctor. A simple blood test can confirm mercury toxicity.

However, not all doctors routinely order this test, so you may need to request it. Private testing is also an option if necessary.


Mercury poisoning is preventable, but awareness is key. Be mindful of your diet, environment, and exposure to potential sources of mercury.
