Is potassium dihydrogen phosphate harmful to the human body

Potassium dihydrogen phosphate in food additives is generally harmless to humans, but as a fertilizer preparation it is harmful to the body.
Potassium dihydrogen phosphate is a relatively stable compound and is odorless and colorless, and is widely used in daily life, among which it is more commonly used as a food additive, such as a bulking agent and moisture retention agent.
It is used in the food production process, and since the dosage is very strict and is added in strict accordance with the national food safety standards, moderate intake will not cause harm to the human body.
However, potassium dihydrogen phosphate is often used as a fertilizer agent in agriculture, which can be harmful to the body in case of long-term exposure, e.g. leading to contact dermatitis, and inadvertent ingestion can also lead to obvious gastrointestinal symptoms, e.g. abdominal pain, diarrhoea, nausea and vomiting.
If obvious discomfort occurs after exposure to or ingestion of potassium dihydrogen phosphate, it is important to go to the hospital in time to avoid delay in treatment.
