HUMAN HEALTH RISK ASSESSMENT FOR ALUMINIUM,

Aluminium distributes into the placenta, foetus, milk, hair, and can be quantified in all tissues and fluids. Greater than 95% of aluminium is eliminated by the kidney, probably by glomerular filtration. Less than 2% appears in bile. Aluminium clearance is characterized by multiple half-lives (t ½), suggesting multiple
