Objective To determine the lead content in the tea substitutes in Jilin province, and put forward suggestions on the setting of the lead limit standard for local specialty substitute tea. Methods Sixty-nine substitute tea samples were purchased in the markets in Jilin province, and the samples were processed by microwave digestion. The lead contents in the samples were determined by graphite furnace atomic absorption spectrometry（GF-AAS）. Results In the 69 tea samples, the positive lead detection rate was 82.6%, and the lead content in all samples was less than 5.0 mg/kg. Conclusion At present, the lead content in different types of tea substitutes in Jilin province is not high, but it is still necessary to revise the lead content limit standard as soon as possible to facilitate quality and safety supervision.
