What are the symptoms of lead poisoning? How to give first aid when lead poisoning happens?
There are usually two symptoms after lead poisoning. If you ingest a lot of lead, it will cause acute symptoms. The specific symptoms are as follows: lead-containing compounds will become ill within 4-6 hours after being absorbed by the human digestive system, and symptoms such as nausea, vomiting, diarrhea and bloody stool will appear. The vomit is white and milky white, because lead chloride will solidify, and the stool is black or bloody, because the stool contains lead sulfide and other substances, and the usual symptom is abdominal cramps. Some patients with severe poisoning will also have anemia, kidney disease and liver damage, which will seriously endanger human health.

If the intake of lead is not too much, chronic poisoning will occur, showing damage to the nervous system. Patients generally have motor or sensory disorders, because the limbs are numb and weak, which can involve respiratory muscles and endanger life in severe cases. Some patients will have toxic encephalopathy. At the beginning, I will suffer from insomnia, inattention, and gradually I will feel irritable. In severe cases, people will be in a coma.

Lead is a heavy metal, which is very harmful to human body. Therefore, first aid measures should be taken immediately after lead poisoning. If the patient eats less than 3 hours by mistake, and the patient is more conscious, he can induce vomiting and gastric lavage. At home, he can give the patient a certain amount of water first, and then put long chopsticks into the patient's throat to stimulate the patient to spit out what he has eaten by mistake, so as to reduce the harm of lead to the human body. Patients with abdominal pain should be given egg white, milk or soybean milk in time to protect gastric mucosa. Most importantly, if the patient loses consciousness, he should lie on his side to prevent the patient from choking, remove foreign bodies from the patient's mouth, keep breathing unobstructed, and avoid foreign bodies entering the respiratory tract to cause the patient to suffocate.
