Pencil lead will not be poisoned if you eat a relatively small amount, but if you ingest too much, you may experience poisoning symptoms. Nowadays, pencils do not contain lead, basically made of graphite and binder, a small amount of accidental ingestion will not be poisoned. If ingested in excess, there is still a possibility of poisoning, because the outside of the pencil is wrapped in paint, which has a little lead content, excessive intake may lead to lead poisoning, making the patient nausea and vomiting, dizziness and other symptoms, and generally may be taken to gastric lavage for treatment. If a small amount is ingested, the possibility of poisoning is not very high, because the structure of graphite is relatively stable, and there is no substance in the human body that can destroy it. However, parents should pay attention to their children’s care in daily life to avoid accidental ingestion by children, which may affect their health. If parents find that their children accidentally eat too much, they should go to the hospital in time.
