초록
The purpose of this study was to analyze harmful heavy metals, sulfur dioxide and residual pesticides in 27 kinds of oriental medical materials. This study was carried out on 27 samples of oriental medical materials. The GC-ECD(Varian, CP-3800) was used to analyze residual pesticides. ICP-OES(Varian, Vista-MPX) was used to analyze lead, arsenic, cadmium. Mercury was analyzed by amalgamation method. A modified Monier-Williams method was used to analyze sulfur dioxide. Arsenic was detected less than 3(㎎/㎏) in 14 samples and was not detected 13 samples. Lead was detected less than 5(㎎/㎏) in 15 samples and was not detected 12 samples. Mercury was detected less than 0.2(㎎/㎏) in 15 samples and was not detected 12 samples. Cadmium was detected more than 0.3(㎎/㎏) in 3 samples was detected less than 0.3(㎎/㎏) in 16 samples and was not detected 11 samples. A few residual pesticides was detected, but all residual pesticides was safe. Sulfur dioxide was detected in all samples, but all residual sulfur dioxide was safe.
