Abstract:A method for the determination of heavy metals in edible roses in Yunnan province was established by microwave digestion and atomic fluorescence spectrometry.To determine the content of heavy metal As，Pb，Hg in edible roses，the conditions of the microwave digestion and instrument were investigated and optimized.The results showed that there were good linearity among the concentration of As，Pb and Hg vary from 1.0 μg/L to 100 μg/L，1.0 μg/L to 80 μg/L，0.4 μg/L to 10 μg/L，detection limits of As、Pb、Hg were 0.005 3，0.022 7，0.007 9 μg/L.The recovery of standard addition was proved to be 90.2%-107.5% in samples and the relative standard deviate （RSD）was below 5.0 %.The contents of As，Pb and Hg in six villages of a city in Yunnan province were 0.016 mg/kg-0.113 mg/kg，0.225 mg/kg-0.308 mg/kg and 0.000 2 mg/kg-0.001 2 mg/kg respectively.Compared with the national standard of food safety，the content of Pb in edible rose was found to exceed the standard.
