Donici and colleagues measured many elements in red and white wines from Bujoru, Smulti, and Oancea. Red cultivars are excluded. Global recovery was 84.6% to 100.9%. No white-wine lead cell was recovered from Tables 1 and 2, so lead is a data gap for the white rows even though an all-sample lead average is printed.
Key numbers
Authors’ white-group figures, µg/L: cadmium 0.11; mercury 0.20 in the abstract; a results sentence prints both 0.24 µg/L and 0.20 µg/L for white wines; total arsenic 12.45. Arsenic, mercury, and chromium are totals.
Clean white cells in Table 1, mean ± standard deviation, n = 3, µg/L, include Bujoru Muscat Ottonel 2015 cadmium 0.11 ± 0.02, mercury 0.34 ± 0.08, arsenic 14.16 ± 2.26. Some other cadmium cells have significance letters fused to the decimal in the text layer and are not copied. Table 2 white nickel and total chromium cells are printed by center, cultivar, and year. One clean pair is Oancea Muscat Ottonel 2016 nickel 263.92 ± 2.54 µg/L and chromium 923.62 ± 2.05 µg/L. Cells marked LOQ are below the limit of quantification and are not entered as zero.
Methods (brief)
0.5 mL wine was microwave digested and measured by ICP-MS. Triplicates n = 3.
Evidence fitness
The white-group figures and the clean cells support a white-wine note for cadmium, mercury, arsenic, nickel, and total chromium. They do not support a white-wine lead number.
Limitations
Lead is not recovered for white wine. Fused significance letters block some cadmium cells. Red rows are excluded.
