Table 1 Aluminum—external and dietary contact

From: Migration of aluminum from food contact materials to food—a health risk for consumers? Part I of III: exposure to aluminum, release of aluminum, tolerable weekly intake (TWI), toxicological effects of aluminum, study design, and methods

Examples of external contact Examples of dietary contact
Construction materials, including alloys (e.g., vehicle construction, aerospace, suitcases, facades, tent construction) Packaging and containers (beverage and food cans, coffee pots, outdoor cutlery and dishes, coffee capsules, household aluminum foil)
Electrotechnology, including alloys (e.g., electrical conductors) Nanoparticles in sunscreens
Fuel for solid-fuel rockets (up to 30% Al) and pyrotechnics Foodstuffs
Pigments for paints (e.g., “silver” bronze paints) Toothpaste (e.g., AlF3: caries prophylaxis)
Metal polish (Al2O3: paste, suspension in MeOH or H2O) Pharmaceuticals (e.g., heartburn medicines—pH-regulation; vaccine adjuvants)
Vaccine adjuvant—(increases the immune reaction)
Organic syntheses (e.g., LiAlH4: reducing agent) Cosmetics (e.g., deodorants–antitranspirants)
Jewelry and ornaments Food additives (e.g., as colorants or stabilizers)
