Content and Risk Assessment of 25 Inorganic Elements in Diamond Mountain Wind
Objective:Exploring the content of inorganic elements in Diamond Mountain Wind provides scientific basis for the resource development and safety of Diamond Mountain Wind medicinal herbs. Method:Microwave digestion ICP and ICP-MS were used to determine the content of 25 inorganic elements,including Li,Be,Ti,V,Cr,Co,Ni,Cu,Zn,Ga,As,Sr,Cd,Sn,Sb,Ba,Hg,Tl,Pb,Bi,Mg,K,Fe,Mn,Ca etc. Result:The higher content of inorganic elements in Diamond Moun-tain Wind is Ca,K,Mg,Ti,Zn,Fe,Sr,Ba in sequence. The detection content of harmful element Cd in two batches of samples exceeds the limit value of 0.3 mg/kg specified in the "Green Industry Standard for Pharmaceutical Plants and Prepa-rations in Foreign Trade",and the comprehensive pollution risk assessment of Nemero is light pollution. The comprehen-sive pollution risk assessment of Nemero in the other three batches of samples is safe. Conclusion:Diamond Mountain Wind contains rich inorganic elements,which can provide scientific basis for its clinical medicinal safety.
