Yes, working in an office full of 5 feet of liquid mercury would be extremely unhealthy and incredibly dangerous, leading to severe health consequences and likely death.
Here's why:
Mercury Toxicity: Liquid mercury (elemental mercury) is highly toxic. While it's not easily absorbed through intact skin, it readily evaporates into an invisible, odorless vapor, even at room temperature.
Inhalation Hazard: Inhaling mercury vapor is the primary route of exposure and is incredibly dangerous. The lungs efficiently absorb mercury vapor into the bloodstream, where it then travels throughout the body, including the brain and kidneys.
Health Effects of Mercury Poisoning:
Neurological Damage: Mercury is a potent neurotoxin. Exposure can lead to severe neurological symptoms like tremors, memory loss, insomnia, irritability, anxiety, depression, personality changes, and difficulty with coordination. This can be permanent.
Kidney Damage: It can cause severe kidney damage, potentially leading to kidney failure.
Respiratory Issues: High levels of vapor can cause lung damage, including chemical pneumonitis.
Digestive Issues: Nausea, vomiting, and diarrhea can occur.
Other Symptoms: Weakness, fatigue, headaches, and skin rashes.
