Determination of trace metal concentrations in ginseng ( Panax Quinquefolius (American)) roots for forensic comparison using Inductively Coupled Plasma Mass-Spectrometry

Highlights • Concentrations of 28 elements determined in ginseng roots from different sources. • Analysis by acid digestion and inductively coupled plasma mass-spectrometry. • Considerable variation in results between different roots and sources. • Statistical analysis enabled discrimination of geog...
