Determination of heavy metal elements and agrochemical remain in Pinellia ternata / 中成药

ABSTRACT

AIM: To determine trace elements lead,cadmium,arsensic,mercury and agrochemical 666,DDT in Pinellia ternata. METHODS: Atom absorbtion spectrophotometry,atom fluorescene spectrum and Gas Chromatography were used. RESULTS: The content of lead in Pinellia ternata was 1.9438-3.6938 mg/kg,that of cadmium was 0.3988-1.9440 mg/kg,that of arsenic was 0.1940-0.9643 mg/kg,that of mercury was 0.0040-(0.1420) mg/kg,The content of total BHC was 0.04%-0.57%,that of total DDT was 0.03-0.07%. CONCLUSION: The content of heavy metal and that of BHC and DDT is up to correlative regulation.
