In a group of workers exposed to aluminium flake powders, blood and urine concentrations of aluminium were assessed before and after vacation. Another group was investigated after retirement. Workers currently exposed to aluminium flake powders had urinary concentrations of the metal 80-90 times higher than those in occupationally non-exposed referents. The calculated half life for concentrations of aluminium in urine was five to six weeks based on four to five weeks of non-exposure. Among the retired workers the half lives varied from less than one up to eight years and were related to the number of years since retirement. These results indicate that aluminium is retained and stored in several compartments of the body and eliminated from these compartments at different rates.
在一组接触铝粉的工人中，在休假前后对其血液和尿液中的铝浓度进行了评估。另一组在退休后接受了调查。目前接触铝粉的工人尿液中该金属的浓度比职业未接触对照者高80至90倍。根据四至五周的无接触情况计算，尿液中铝浓度的半衰期为五至六周。在退休工人中，半衰期从不到一年到八年不等，且与退休后的年数有关。这些结果表明，铝在体内的多个隔室中潴留和储存，并以不同速率从这些隔室中排出。
