Aluminum exposure can lead to several safety issues. Chronic exposure may lead to neurological problems, including cognitive dysfunction and Alzheimer's disease, though the link is still debated. It can also cause bone diseases by leaching calcium from bones. Aluminum may contribute to kidney dysfunction and anemia. In occupational settings, inhalation of aluminum dust can lead to respiratory issues. It's important to note that the human body naturally eliminates aluminum, and the risk of toxicity is generally low under normal conditions. However, in certain medical conditions or with high exposure, aluminum can accumulate and pose health risks.
