Determination of aluminium in liver from reindeer, moose and sheep by electrothermal atomic absorption spectrometry

Aluminium in liver from reindeer, moose and sheep from the northeast part of Norway was determined by graphite furnace atomic absorption spectrometry following digestion of the samples with nitric acid. The concentration of aluminium in the liver was markedly higher for reindeer than for moose and sheep; the median values obtained were 0.56 μg g−1 Al (wet wt.) for 101 reindeer, 0.06 μg g−1 Al for 72 moose and 0.09 μg g−1 Al for 40 sheep. The detection limit of the method was 0.01 μg g−1 Al. The NIST SRM 1577a Bovine Liver was also analyzed.
