Methods According to relevant national standards, the content of Pb, Cd, Cr, Ni, As and Hg were measured by atom absorption spectrophotometry and atomic fluorescence spectrometry respectively, and 11 kinds of pesticide residues including carbendazim, carbofuran, acetamiprid, imidacloprid, chlorpyrifos, dimethoate, triazophos, kelthane, cypermethrin, fenvalerate and bifenthrin were determined by liquid chromatography and gas chromatography. Then the results were analyzed and evaluated according to the limited standards of above heavy metals and pesticide residues in national standards. Results The 4 kinds of herb teas had different content of heavy metals. There was no limited standard for Ni, and apart from that, the content of other elements in jasmine tea, rose tea and white chrysanthemum tea were all below the limitations, while the Cd concentration in honeysuckle tea exceeded the standard value. Acetamiprid was * 通讯作者 :,, huayuejiang8@163.com *Corresponding author: JIANG Yue-Hua, Engineer, Quality Supervision and Testing Center of Subtropical Fruits and Vegetables, Ministry of Agriculture, Nanning , China. huayuejiang8@163.com

2 detected in the 4 kinds of herb teas with the content ranged from to mg/kg and the concentration of acetamiprid in white chrysanthemum tea exceeded the limitation. The concentrations of 11 kinds of pesticide residues in jasmine tea, rose tea and honeysuckle tea were all below the limitations. Conclusion There were potential safety hazards of heavy metals and pesticide residues pollution in honeysuckle tea and chrysanthemum tea respectively, so the monitoring of health quality in tea plantations should be strengthened to ensure the safety of herb teas.
