Pb and Cu Levels in Tea Samples Marketed in Beijing

Abstract

Abstract: To evaluate the safety status of teas marketed in Beijing, 57 tea samples randomly collected for Beijing market were analyzed for Pb and Cu by atomic absorption spectrometry. Pb concentration is found to be in the range 0.198～6.345mg/kg DW, with only one sample exceeding the maximum permissible concentration (MPC) of 5mg/kg DW set by Chinese Ministry of Health. Cu concentration is in the range 1.790～48.19mg/kg DW, with all samples below the MPC of 60 mg/kg DW for Cu. The present study showed that the safety status of teas marketed in Beijing is optimistic.

Key words: tea, Pb, Cu, safety status
