The Bottom Line. A broken mercury-containing thermometer can be toxic if the vapors are inhaled. The risk of poisoning from touching or swallowing mercury from a broken thermometer is low if appropriate clean-up measures are taken.
Just so, can mercury be absorbed through the skin?
ROUTES OF EXPOSURE: Elemental mercury is toxic primarily through inhalation of mercury vapors. It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Elemental mercury droplets may be absorbed through eye contact.
Beside this, how do you clean mercury off the floor?
Sprinkle sulfur powder over the contaminated area and rub it gently all over the surface and into the cracks with a paper towel. Sulfur powder binds with mercury. Use a paper towel dampened with water followed by wiping with another damp paper towel to clean up the sulfur and mercury.
How do you dispose of broken thermometers?
Wipe the area with a damp cloth. Put collected mercury and the cloth in the same bag and seal it. In case mercury has been spilled over the cloth, dispose of them in a sealed bag. Do not wash them or put them in washing machine.
How long does it take for mercury to evaporate?
Unlike some liquids, mercury vapors are colorless and odorless. This makes it hard to detect without the use of specialized instruments. A pea-sized drop of mercury that goes undetected can take up to 384 days to fully vaporize.
How long does mercury stay in the body?
Mercury does not stay in the body forever. It takes about six months to a year to leave the bloodstream once exposure stops. Some researchers think mercury can permanently damage the nervous system in children.
Is thermometer mercury harmful?
The small silvery ball in a mercury thermometer can be dangerous if the glass breaks and the mercury is not cleaned up properly. The mercury will evaporate and can contaminate the surrounding air and become toxic to humans and wildlife.
What do you do if you break a mercury thermometer?
Slowly and carefully squeeze mercury onto a damp paper towel. Alternatively, use two pieces of cardboard paper to roll the mercury beads onto the paper towel or into the bag. Place the paper towel in a zip locking bag and secure. Make sure to label the bag as directed by your local health or fire department.
What happens if you inhale mercury?
The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.
What level of mercury is considered toxic?
When the urine mercury concentration exceeds 100 μg/L, neurological symptoms can develop, and the level of 800 μg/L or above can be fatal.
