What are some common sources of aluminum in the environment?

Aluminum is the most abundant metal in the Earth's crust, and it is widely present in the environment. Common sources include: 1) Natural weathering of rocks and soil, which releases aluminum into the environment. 2) Industrial processes such as aluminum production, which can release aluminum into the air and water. 3) Food and water, where aluminum can be found naturally or as a result of contamination. 4) Household products like aluminum foil, cans, and cookware, which can contribute to aluminum exposure. 5) Medications and vaccines, which sometimes contain aluminum as an adjuvant. 6) Cosmetics and personal care products, which may contain aluminum compounds. These sources contribute to the overall aluminum exposure in the environment and to humans.
