This chapter discusses the electrochemical stripping analysis of trace and ultratrace concentrations of toxic metals and metalloids in foods and beverages. Electrochemical stripping analysis offers several unique advantages such as high sensitivity, selectivity, ability to identify a wide range and forms of metals and metalloids in various matrices, ease of identification and elimination of interferences and contamination, and substantially lower costs than most of the other trace analytical methods. Both variants of electrochemical stripping analysis have provided extremely sensitive and selective methods for the analysis of many substances at trace and ultratrace concentrations, as well as for multicomponent analyses in a single sample solution. The nondestructive nature of these methods permits further analyses on the same sample solution by other analytical methods. The surface area of the electrode, duration, and rate of pre-concentration are key factors that can influence the sensitivity of this method. At a constant electrode surface area and pre-concentration time, the sensitivity is influenced by the stirring of the solution or electrode rotation rate, and it is also dependent on the solubility of the analyte in mercury. The analytical applications of stripping analysis to foods and beverages are also elaborated in the chapter.
