Answer on Inorganic Chemistry Question for Anastasia
hello, my question is not exactly a chemical one, but I would like to ask whether mangenese dioxide is dangerous if ingested or inhaled in very small amount
The absorption of manganese dioxide by the stomach or intestine is limited in comparison with that from inhalation; it is very unlikely, therefore, that a sufficient quantity of material could be ingested to give rise to symptoms which require first aid. If a person has ingested the material give plenty of water of milk to drink and seek medical advice. The only acute reaction to inhalation is the so called "metal fume fever" although this is very unlikely; symptoms are intoxication and elevated temperature and should be treated by removal of the patient to fresh air, if symptoms persist seek medical advice.
