1. accidental ingestion of large amounts of soluble aluminum salt aluminum ammonium sulfate can cause stomatitis, gastritis, and even hemorrhagic gastritis in severe cases. 2. inhalation of high concentrations of aluminum chloride can stimulate the mucous membrane of the upper respiratory tract, producing acute bronchitis and serious interstitial pneumonia. 3. inhalation of vapor from aluminum smelting and aluminum fluoride during aluminum electrolysis can lead to bronchial asthma attacks. 4. inhalation of alkyl aluminum (diethylaluminum chloride, triethylaluminum, triisobutylaluminum chloride) vapor and fumes can produce clinical manifestations similar to metallic fume fever, and inhalation of high concentrations can cause chemical pneumonia and pulmonary edema, Inhalation of alkyl aluminum (diethylaluminum chloride, triethylaluminum, diisobutylaluminum chloride, triisobutylaluminum) vapors and fumes can produce clinical manifestations similar to metal fume fever, and inhalation of high concentrations can cause chemical pneumonia and pulmonary edema. 5. Eye and skin contact with the original alkyl aluminum solution can cause burns.
