INTRODUCTION
In recent years, there has been increasing interest in
determining the concentration levels of heavy metals
in various food products. For example, white sugar,
which is known to be one of the purest food substances
produced on an industrial scale, contains some metal
impurities depending on the quality of sugar beet or
cane used in its production technology. The allowable
trace metal contaminations of white sugar have been
described by national and international white sugar
standards. Among them, the Codex Alimentarius Commission
(1990) states the maximum allowable level as
1 mg kg-1 for As, Cu, and Pb.
