Strong acid poisoning

Strong acids mainly refer to sulfuric acid, nitric acid, and hydrochloric acid, all of which have strong irritant and corrosive effects. Poisoning is mostly caused by occupational contact, inhalation, or accidental ingestion. Local contact of the agent causes local congestion, edema, necrosis, and ulceration, and even perforation of hollow organs, forming scars, strictures, and deformities. Through the blood circulation, it causes damage to internal organs, with the liver and kidneys being more severely affected.
