Aluminum can change the cell morphology of organisms, and the toxicity of aluminum ions is manifested in three aspects:

1. Toxic to microorganisms: at low mass fraction, aluminum has a certain stimulating effect on ammoniating bacteria, nitrifying bacteria and denitrifying bacteria in soil; when the mass fraction is high, it acts as an inhibitory effect and an adverse effect on the activity of aerobic bacteria and anaerobic bacteria in water, but the microorganisms have self-healing ability, and if they are cultured at a certain concentration for a period of time, the microorganisms can develop resistance to aluminum poisoning;

2. Harm to animals and plants: aluminum poison has become one of the main factors that inhibit plant growth in acidic soil. It mainly harms the roots of plants, thus affecting the absorption of nutrients and water by crops; the concentration of aluminum ions is higher than 0.5mg/L can cause some fish to die;

3. Aluminum is beneficial to human body to a certain extent. It can alleviate some of the poisoning of lead to human body. However, excessive intake of aluminum will be distributed in human body's liver, stomach, spleen, brain, thyroid and other organs, resulting in premature aging, dementia, anemia and some bone diseases. The daily intake of aluminum for adults should not exceed 35mg.
