Abstract

A survey was conducted on the presence of total and hexavalent chromium in Lager beers to understand the variability between different styles of Lager beer packaged in glass or can and estimate daily intake of total Cr and hexavalent chromium from beer. Graphite-Furnace Atomic Absorption Spectroscopy using validated methodologies was applied. Selective extraction of hexavalent chromium was performed using a Chromabond NH2/500 mg column and elution with nitric acid. The detection limits were 0.26 and 0.68 µg L-1 for total Cr and Cr(VI), respectively. The mean content of total Cr ranged between 1.13 µg L-1 in canned Pale Lager and 4.32 µg L-1 in Low Alcohol beers, whereas the mean content of Cr(VI) was <2.51 µg L-1. Considering an intake of 500 mL of beer, beer consumption can contribute approximately 2.28-8.64 % and 1.6-6.17 % of women and men recommended daily intake of chromium, respectively.
