Zinc poisoning

Zinc is a necessary trace element for the human body. Ensuring the nutrient supply of zinc is of great significance for promoting the growth and development of the human body and maintaining health. However, the supply of zinc and the poisoning dose are very close, that is, the seat belt is very narrow. For example, the zinc supply for humans is 10-20 mg / d, and the poisoning quantity is 80-400 mg. Zinc poisoning is mainly due to the use of galvanized vessels to prepare or store acid drinks. At this time, the acid solution can decompose more zinc and cause poisoning. Other reasons include taking zinc oxide (usually an astringent) or zinc sulfate (usually used in the treatment of conjunctivitis) by mistake or taking zinc oxide (usually a mildly astringent or anticorrosive dusting powder) on a large area. Erosion of the mouth, pharynx, and digestive tract, swelling of the lips and glottis, abdominal pain, diarrhea, vomiting, and water and electrolyte disturbances after misuse of zinc salts. In severe cases, crises such as increased blood pressure, shortness of breath, dilated pupils, shock, and convulsions can be seen.
