And, Green Trade Standards of Importing & Exporting Medicinal Plants & Preparations was used as the standard to evaluate the pollution condition of Cu, Pb, As, Cd, Hg in Chinese crude drugs. Chinese crude drugs were contaminated by heavy metals in different levels. The content of Cu, Pb, As, Cd, Hg exceeded the limit of the standard and the percentage was 21.0%, 12.0%, 9.7%, 28.5%, 6.9%, respectively; the phenomena of two, three and four metals exceeding limited standard simultaneity in a drug were also found and the percentage was 4.6%, 1.5%, 0.7%, respectively; the content of heavy metals in Radix Platycodi, Radix Asari and Rhizoma Coptidis was higher among the thirty-six Chinese crude drugs; All of the content of five heavy metals in Barbary Fructus Lycii Rhizoma Anemones Raddeanae, Radix Panacis Quiquefolii and Fructus Aurantii were below the l
