Toxic Metals in Selected Traditional Chinese Medicinals

CODEN: JFSCAS

Abstract

An examination of traditional Chinese medicine preparations that purport to contain endangered-species products revealed the presence of inorganic forms of mercury and arsenic. We analyzed 12 types of commercially produced herbal ball preparations (n = 85) using X-ray fluorescence spectroscopy and atomic absorption spectroscopy. Mercury levels ranged from 7.8 to 621.3 milligrams and arsenic levels ranged from 0.1 to 36.6 milligrams per ball. The recommended adult dose for these preparations is two balls daily. At this dose the maximum elemental intake per day is up to 73.2 milligrams of arsenic and 1.2 grams of mercury. While arsenic poisoning is usually associated with foul play, and mercury poisoning is usually associated with environmental contamination, forensic scientists should be aware that these elements may be consumed in connection with cultural and lifestyle preferences.
