Aluminium is one of the most abundant elements in the environment and is released from both natural and anthropogenic sources. Representative values of aluminium concentrations in the background environment and in man are selected from available data and a pathway analysis is performed utilising the exposure commitment method. Using a derived estimate of the body burden (60 mg), a representative value for dietary intake (20 mg day-1) and fractional absorption of 0.01, a mean retention time of Al in the body of 300 days is obtained. This corresponds to a biological half-time of 210 days. The assessment indicates that an average dietary intake rate of 20 mg day-1 contributes 660 μg kg-1 of aluminium to the body, while inhalation of aluminium in air makes, in comparison, a negligible contribution to the body content.
