Can a broken mercury thermometer cause mercury poisoning?

Hello:
1.
If a thermometer containing mercury accidentally falls and breaks, could it lead to inhalation mercury poisoning? (I used a broom to sweep up the mercury, but I'm concerned about inhaling mercury during the cleanup process.)
2.
How can I determine if I have inhaled mercury? Is there a simple way to rule it out, or should I seek medical attention?
3.
During the cleanup, a 2-year-old child was present, and I'm worried about the child inhaling mercury.
If the child did inhale it, how long would it take for symptoms to appear? Would it be immediate or several days later?
Thank you for your response!

Hello: In general, when dealing with a broken thermometer, you can use a syringe or a suction bulb to collect the mercury and place it in a sealed plastic container for disposal by environmental protection personnel.
If the liquid mercury from the thermometer accidentally spills, it may turn into a gaseous state, producing mercury vapor, which can potentially cause poisoning in a confined space.
Acute mercury poisoning can present with symptoms such as cold extremities, weakness, nausea, vomiting, coughing, and chest tightness.
Generally, the amount of mercury in a mercury thermometer is not very large, and the evaporation rate is not rapid; as long as it is handled within 1 to 2 hours after breaking, it will not evaporate significantly.
Therefore, thoroughly recovering the mercury and sealing it, while ensuring proper ventilation in the indoor air, will mitigate the risk of poisoning.
If acute poisoning symptoms occur, it is advisable to go directly to the emergency room of a hospital, where a physician will assist with differential diagnosis.
Thank you for your inquiry.

More Info

When a mercury thermometer breaks, it can indeed pose a risk of mercury exposure, particularly if the mercury is inhaled or comes into contact with skin. Here’s a detailed breakdown of the potential risks, symptoms of exposure, and recommended actions to take.

1. Risk of Inhalation and Exposure
When a mercury thermometer breaks, it releases tiny beads of mercury, which can easily scatter. If these beads are inhaled, they can lead to mercury poisoning. Mercury vapor is particularly dangerous because it can be absorbed through the lungs and enter the bloodstream, potentially causing toxic effects on the nervous system, kidneys, and other organs.

In your case, since you mentioned using a broom to clean up the mercury, there is a possibility that you could have inhaled some of the vapor, especially if the area was not well-ventilated. However, the risk of significant exposure depends on several factors, including the amount of mercury released and the duration of exposure.

2. Symptoms of Mercury Poisoning
Symptoms of mercury exposure can vary based on the level and duration of exposure. Acute symptoms may include:
- Coughing or difficulty breathing
- Chest pain
- Nausea or vomiting
- Fatigue or weakness
- Tremors or shaking
- Mood changes or irritability
Chronic exposure can lead to more severe neurological symptoms, including memory problems, insomnia, and tremors. If you experience any of these symptoms, it is crucial to seek medical attention promptly.

3. Monitoring for Symptoms
If you are concerned about potential mercury inhalation, it is advisable to monitor yourself for any symptoms. If you notice any respiratory issues, neurological symptoms, or general malaise, you should consult a healthcare professional.

4. Safety Precautions for Children
Regarding your concern about the presence of a 2-year-old child during the cleanup, young children are particularly vulnerable to the effects of mercury exposure. If there is any suspicion that the child may have inhaled mercury vapor or come into contact with it, it is essential to seek medical advice immediately. Symptoms in children may not appear immediately; they can manifest within hours to days after exposure.

5. Cleanup Recommendations
For future reference, if a mercury thermometer breaks, follow these steps for safe cleanup:
- Do Not Vacuum: Avoid using a vacuum cleaner, as this can spread mercury vapor.

- Use Gloves: Wear gloves to prevent skin contact with mercury.

- Seal in a Container: Use sticky tape or duct tape to pick up small beads of mercury and place them in a sealed container.

- Ventilate the Area: Open windows and doors to ventilate the area and disperse any mercury vapor.

- Dispose Properly: Contact local hazardous waste disposal services for guidance on how to dispose of mercury safely.

6. Medical Evaluation
If you have concerns about exposure or if symptoms develop, it is advisable to seek medical evaluation. A healthcare provider can perform blood tests to measure mercury levels and assess any potential health impacts.
In summary, while there is a risk of mercury exposure from a broken thermometer, the actual risk depends on the circumstances of the incident. Monitoring for symptoms and seeking medical advice if any concerns arise is the best course of action. Always prioritize safety and proper cleanup procedures to minimize risks associated with mercury exposure.
