Will I get poisoned if I accidentally inhale a little oxalic acid?
Whether accidentally inhaling oxalic acid causes poisoning varies from person to person and depends on specific circumstances.
1. Yes
Oxalic acid is a strongly acidic substance. If inhaled in large amounts, it can enter the body through the respiratory tract and, via the bloodstream, disrupt the body's acid-base balance, leading to symptoms of poisoning. This may be accompanied by nausea, vomiting, and diarrhea. Under a doctor’s guidance, patients can take oral medications to help eliminate oxalic acid, such as calcium gluconate or calcium lactate.
2. No
If only a small amount of oxalic acid is inhaled, poisoning typically does not occur. When the concentration of oxalic acid in the air is low, the amount absorbed by the body is usually minimal, so there is generally no need for excessive concern, and it will not affect health. It is recommended to drink water promptly and breathe fresh air to alleviate any potential discomfort. If symptoms develop, however, medical attention should be sought immediately.
In addition, individuals should avoid prolonged exposure to environments containing oxalic acid vapor to prevent harm to health.
