What happens when the human body is exposed to oxalic acid?

Oxalic acid is a strong organic acid, which is toxic. Long-term exposure can be absorbed into the body through the skin and respiratory tract, destroying the acid-base balance in the body, causing metabolic disorder, affecting the distribution of calcium ions in the body, changing the blood composition, and even leading to death in severe cases. After the skin comes into contact with oxalic acid, it should be washed with water in time. It is very corrosive. If the local skin is hard, it means that the skin is damaged. It may be suggested to go to the hospital for dermatological examination and external application of drugs. In addition, wearing rubber gloves can avoid the harm of oxalic acid to the skin.
