Pawlaczyk and colleagues report quantitative total mercury and semi-quantitative fingerprints for other elements. Only total mercury is copied. Subgroup sample sizes are not printed. No mercury recovery percentage is printed. None of the samples exceeded 20 µg/L.
Key numbers
Total mercury averages, µg/L: Speyside 1.82, USA 4.56, Highland 2.13, Irish 2.16. n = 20 overall.
Methods (brief)
Cold-vapor atomic absorption spectrometry for total mercury. Other elements are semi-quantitative ICP-MS signals, not concentrations.
Evidence fitness
The regional averages support a total-mercury note for whisky. They do not support lead, cadmium, or other metals from the semi-quantitative figures.
Limitations
Subgroup n is not printed. No mercury recovery percentage. Mercury is total, not methylmercury.
