Macro- and Micro-Elements in Tea (Camellia sinensis) Leaves from Anhui Province in China with ICP-MS Technique: Levels and Bioconcentration
The aim of this study was to analyze levels and bioconcentration potential of 4 macro-elements (Ca, K, Mg, P) and 7 micro-elements (Al, Mn, Fe, Cu, Zn, Cd and Pb) in tea leaves collected from tea orchards in Anhui, China by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that the most abundant elements in tea young leaves were Ca, K, Mg and P (Ⅰ, >30 mg·g-1), followed by Al, Mn, Zn and Fe (Ⅱ, 02~30 mg·g-1), Cu, Pb and Cd (Ⅲ, <0.05 mg·g-1), while in mature leaves were Ca, K, Mg and Al (Ⅰ, >30 mg·g-1), followed by P, Mn, Zn and Fe (Ⅱ, 02~30 mg·g-1), Cu, Pb and Cd (Ⅲ, <005 mg·g-1). P and Mn were highly bioconcentrated, Cu, Pb and Cd in tea leaves were found to be below the legal limits. Cluster analysis demonstrated that there is no significant difference in the mineral composition between two tea cultivar.
