- Abstract
This article discusses the concentrations of heavy metals in teas sold in the Beijing market of China. Samples from different provinces of China, including four main types of tea: green, black, Oolong, and scented teas were analyzed using a graphite furnace atomic absorption spectrometer. According to the authors, the results showed that the lead and copper contents in teas marketed in Beijing were generally within the Chinese maximum permissible concentration (MPC), with no sample exceeding the Chinese MPC for copper and only a small proportion of the samples exceeding the Chinese MPC for lead.
