摘要：
In this study, electrothermal atomic absorption spectrometry (ETAAS) was used for determination of lead and cadmium in Macedonian white wines. Wine samples, without prior purification, were directly injected into the ETAAS system, using matrix modifiers for Pb and Cd. The standard addition method was used for quantitative analysis of Pb and Cd content. Reliability of the method was verified by determination of selected validation characteristics. The results of the measurements indicated satisfactory precision and accuracy, confirming that the method is accurate and convenient for quantitative analysis. The lead and cadmium concentrations were ranged between 2–28.5 and 0.4–5.69 μg/L, respectively. The levels were below the maximal allowed concentration in wine and compare well with those reported for similar wines from other parts of the world.
