SUMMARY
EVALUATION OF HEAVY METAL CONTENTS FN MEDICINAL HERBS AND SOILS USING ICP- MS TECHNIQUE USING ICP- MS TECHNIQUE
To explore the possibility of translocation of heavy metals into patients, the present study conducted soils and herbal plants samples collected at 20 positions in 2 gardens of traditional herbal medicinal plants and estimated contents II heavy metals using ICP- MS techniques Based on the t- test and MANOVA, the significant differences of heavy metal contents between surface and 30 cm soil and in perennial or short herbal plants were found. The bioaccumulation of As. Cd. Ni, Pb (especially Cd) in Paederia tomentosa L. Caryopteris incana were extreemly recognized. However, the presence of toxic metals in different plants led to the conclusion that prolonged consumption of such medicinal plants may be detrimental to health. Strict quality-control mechanisms must be instituted so that use in humans and animals is safẹ
