Harm of aluminum powder to human body

There are three ways to prevent the harm of aluminum: first, it is suggested that the city water supply company should not use aluminum salt [such as potassium aluminum sulfate (Kai (SO4) 2] as water purification agent; second, try not to use aluminum products as cooking utensils; third, eat less food containing aluminum salt additives (such as fried dough sticks).


Once aluminum powder enters the human body, it first deposits in the brain, which may lead to brain damage and serious memory loss, which is a special symptom of Alzheimer's disease. The researchers involved in the work said that experiments on mice showed that they had measurable levels of aluminum in their brains after just one cup of water treated with aluminum salts. Studies on mice have found that trace amounts of aluminum mixed in drinking water enter the brains of mice and accumulate there. Researchers on dementia patients found that 30% of the brain neocortex aluminum concentration is greater than 4 μ g / g (dry weight), the content of aluminum in brain neuron nucleus of patients is 4 times that of healthy people, and the maximum is 30 times. Researchers believe that if aluminum accumulates in the brain over time, it can kill neurons and cause memory loss. A scientist said: we have been drinking purified water and eating food containing aluminum salt all our lives, so we have accumulated a lot of aluminum in our bodies when we are very old. He pointed out that the incidence rate of Alzheimer's disease has increased worldwide over the past 70 years. Aluminum is also used in food emulsifiers, he said.




Aluminum can directly damage the activity of osteoblasts and inhibit the synthesis of bone matrix. At the same time, the absorption of aluminum by digestive system leads to the increase of urinary calcium excretion and the deficiency of calcium content in human body. Aluminum continuously accumulates and carries on the physiological function in the human body, but also can cause encephalopathy, bone disease, kidney disease and non iron deficiency anemia.




Aluminum can also dehydrate the protoplasm of plant cells, then destroy and die. Aluminum combines with pectin in cell wall to strengthen the cross-linking structure of pectin, which hinders plants from absorbing water and nutrition. Aluminum is also closely related to calcium and phosphorus in plants. It can inhibit the absorption and accumulation of calcium and phosphorus in common plants, and also affect their absorption and accumulation of potassium, magnesium, iron, manganese, copper, zinc and other elements. Aluminum is also toxic to aquatic animals. When the pH value is about 5, aluminum hydroxide is deposited in the gills of fish in the form of aluminum hydroxide, which makes it difficult for oxygen to enter into the blood, and the concentration of salt in fish body is out of balance, causing fish to die. The toxic concentration of aluminum to aquatic animals is generally more than 70 μ g / L. The increase of aluminum content in water will lead to a large number of organic matter condensation, resulting in the death of aquatic animals due to lack of nutrition. Aluminum can precipitate phosphorus, which seriously threatens the reproduction of aquatic animals.




Aluminum is harmful to human body and biology. Soluble aluminum compounds are toxic to most plants. Aluminum compounds dissolved in the water of acidic soil make it difficult for common crops to grow normally. Usually, when the dissolved aluminum reaches more than 10-20ppm, plants will appear aluminum toxicity symptoms. Aluminum in soil can combine with soluble phosphate to form insoluble aluminum phosphate, which leads to plant death due to lack of phosphorus.
