Is it harmful to people to boil water with old aluminum pot?

Harmful aluminum pots contain certain chemical elements, and high temperature heating will produce certain toxic substances. If used for a long time, it will do harm to human body. If you cook and boil water with aluminum products for a long time, it will also affect the normal absorption of calcium and phosphorus by the human body.

Aluminum is easily oxidized in air to form alumina film. Alumina film is insoluble in water, but soluble in acidic or alkaline solution. Salt also destroys alumina. Aluminum pots are best not to be used to hold cola or other carbonated drinks. Most metals are harmful if absorbed by human body, and aluminum is one of the harmful metals that are easily absorbed. As a kettle, aluminum is more harmful because of its low melting point and easy decomposition.

Toxicological whisker characteristics of aluminum;

Studies have found that aluminum can damage human brain cells. According to the evaluation of the World Health Organization, the daily intake of aluminum is 0 ~ 0.6 mg/kg, in which kg refers to a person's weight, that is, the allowable intake for a 60kg person is 36mg.

According to GB2760-20 1 1, the residual aluminum should be less than or equal to 100mg/kg. Based on this calculation, a person weighing 60kg need not worry about eating no more than 360g of fried dough sticks every day.

Aluminum is slowly accumulated in the human body, and its toxicity is slow and imperceptible. But once the toxic reaction of metabolic disorder occurs, the consequences are very serious.

Therefore, we must pay attention to prevent the absorption of aluminum and reduce the use of aluminum products in daily life. The harm of aluminum and its compounds to human beings cannot be compared with its contribution. As long as people pay attention to it, it will play a more important role in human society.
