Bora and colleagues measured trace elements by ICP-MS in red and white wines. This note uses the white rows of Table 5. Table 6 is by winemaker and is not split by color, so it is not used. Red cultivar rows are not used.
Key numbers
Table 5 reports mean values in µg/L. The printed White Average row, with no standard deviation on that row, is lead 32.56 µg/L, cadmium 0.28 µg/L, nickel 179.70 µg/L, and chromium 541.17 µg/L. Chromium is 53Cr, not hexavalent. Arsenic, mercury, aluminum, and tin were not measured.
Some printed cultivar averages sit outside the printed range pair for that cultivar, including Feteasca regala lead (average 19.82 ± 1.66 µg/L beside a range 12.08 to 15.70 µg/L), Pinot gris lead, and Busuioaca de Bohotin lead. Aligote chromium endpoints are printed in reverse order relative to the average. Those conflicts are left as printed. This note does not recompute a mean. The methods n (147 white wines) and the Table 5 white cultivar counts (sum 36) are both printed.
Methods (brief)
Wine was microwave digested and measured by ICP-MS. Blank and triplicate samples were analyzed. The authors cite replicate accuracy of 0.8% to 13.1% from an earlier paper.
Evidence fitness
The White Average row supports a white-wine occurrence note for lead, cadmium, nickel, and total chromium. It does not support a red-wine value or a certification limit.
Limitations
Color-pooled Table 6 is excluded. Cultivar averages that fall outside their printed ranges are not repaired. Chromium is not hexavalent.
