【摘要】 采用微波消解-直角加速飛行質(zhì)譜儀(ICP-oTOFMS)對(duì)云南省不同地區(qū)松茸子實(shí)體、菌柄和菌蓋中砷(As)、鎘(Cd)、汞(Hg)、鉛(Pb)的含量進(jìn)行測(cè)定。結(jié)果表明,松茸中As、Cd、Hg、Pb的含量范圍分別為0.208 mg.kg-10.795 mg.kg-1、0.087 mg.kg-10.209 mg.kg-1、0.015 mg.kg-10.038 mg.kg-1、0.144 mg.kg-10.486 mg.kg-1;菌蓋中As、Cd含量均高于菌柄,有顯著差異;菌柄和菌蓋中Hg、Pb的含量無顯著差異。
【Abstract】 A method involving microwave digestion and ICP-oTOFMS was used in determining the contents of arsenic(As),cadmium(Cd),mercury(Hg) and lead(Pb) in Tricholoma matsutake,collected from different areas of Yunnan Province.The results showed that the contents of As,Cd,Hg and Pb in Tricholoma matsutake ranged from 0.208 mg·kg-1 to 0.795 mg·kg-1,0.087 mg·kg-1 to 0.209 mg·kg-1,0.015 mg·kg-1 to 0.038 mg·kg-1,0.144 mg·kg-1 to 0.486 mg·kg-1,the contents of As and Cd in caps were both higher than stipes,the ...
