1. Short-term: Aluminum is a lively metal, which is easy to react with oxygen in the air, forming a dense alumina film on the surface, so the surface of the product is not easy to rust. When using an aluminum kettle, if the gray color alumina film on its surface is not destroyed, and the use time is short, it will generally not cause harm to the human body;
2. Long-term use: long-term use of aluminum kettle to boil water, alumina film is destroyed, aluminum content can be increased by 3-20 times. Aluminum accumulates in the human body and cannot be excreted in the body, resulting in chronic aluminum poisoning. Aluminum has a certain blocking effect on nerve conduction, which can lead to lesions of the nervous system, affecting people's consciousness, thinking, and memory ability, leading to memory loss, mental decline, and even increasing the chance of Alzheimer's disease. In addition, aluminum can be deposited in the bone, resulting in calcium loss, softening the bones, and may also affect the body's absorption of iron and zinc, inducing small cell hypochromic anemia.
