Determination of metal ion content of beverages and estimation of target hazard quotients: a comparative study.

ABSTRACT:

Background

Considerable research has been directed towards the roles of metal ions in nutrition with metal ion toxicity attracting particular attention. The aim of this study is to measure the levels of metal ions found in selected beverages (red wine, stout and apple juice) and to determine their potential detrimental effects via calculation of the Target Hazard Quotients (THQ) for 250 mL daily consumption.

Results

The levels (mean +/- SEM) and diversity of metals determined by ICP-MS were highest for red wine samples (30 metals totalling 5620.54 +/- 123.86 ppb) followed by apple juice (15 metals totalling 1339.87 +/- 10.84 ppb) and stout (14 metals totalling 464.85 +/- 46.74 ppb). The combined THQ values were determined based upon levels of V, Cr, Mn, Ni, Cu, Zn and Pb whi
