Aluminium is used in a wide range of industrial processes such as the manufacture of alloys, window frames, engine parts, aircraft parts, roofs, electric wires etc.
Aluminium is mainly absorbed through the lungs by inhalation of fumes and fine dust particles. Some aluminium is absorbed through the gastrointestinal tract when large amounts of high aluminium containing compounds are ingested, such as antacids. It is largely excreted via the urine, although some is also excreted in the bile.
Measurement of urine aluminium is used to monitor workers occupationally exposed to fumes and dust. Welders have the highest excretion levels among exposed workers.
The half life of aluminium is 8 hours, a relatively short period, at first exposure. However, this increases with the length of exposure, and can reach 6 months after 10 years of exposure.
Recommended sampling time is POST SHIFT - the last 2 hours to immediately following the end of the working week.
The urine pottle used for collection must be free of aluminium contamination.
Aluminium has a half life of approximately 8 hours so samples must be collected post-shift (2 hours to immediately following the end of work day).
Ensure hands are washed and clothes are free of contamination
Urgent testing by arrangement
Aluminium is widespread throughout the environment, so care must be taken when collecting the sample.
A 20 mL urine sample is collected into a sterile aluminium free container at the end of the shift.
The sample collection information provided on this site is Canterbury Health Laboratories recommendation and is based on current best practices, for more information or further details please refer to the latest edition of Worksafe’s : Biological Exposure Index (BEI) review.
Ambient (8 - 24 degrees Celsius)
If overnight - Chilled (2 - 8 degrees Celsius)
Reports issued by Canterbury Health laboratories will have results along with current Normal population Reference Intervals (RI).
