摘要：

Health effects associated with biological uptake of Al depend on the dietary intake (dose) and on bioavailable Al-species originally present in the diet or mobilised from inert species in the gastro-intestinal tract. Analytical techniques capable of fractionating species according to size and charge properties are available for aqueous solutions especially natural waters. When the techniques are combined, i.e. fractionation according to size (e.g. molecular weights) prior to the fractionation according to charge properties, the analytical results are easier to interpret. Thus the quality of the input data for modelling purposes is improved. For biological materials, however, the results obtained using different techniques are operationally defined only. © 1990 Sciences and Technology Letters.
