Abstract

Objectives :The purpose of this study was to analyze persistent pollutants(harmful heavy metals, sulfur dioxide and residual pesticides) in 23 kinds of Korea traditional medical materials. Methods :This study was carried out on 23 samples of Korea traditional medical materials. The examination methods follow the guideline of food and drug administration. Inductively coupled plasma mass spectrometry(ICP-MS) was used to analyze arsenic, cadmium, lead. Mercury was analyzed by amalgamation methods. A modified Monier-Williams method was used to analyze sulfur dioxide. The gas chromatography / electron capture detector (GC/ECD) was used to analyze residual pesticides. Results & Conclusions :Most of the results were within normal limits at baseline. but cadmium was detected over the limits in 1 sample and residual pesticides was detected over the limits in 5 samples.
