  • The metal content of 49 tea leaf samples from three different provinces inVietnamwere determined using inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectrometry (AAS). Total 18 elements in tea leaves were determined including macro element such as Al, Ca, K, Mg, Mn; trace element such as Na, Ba, Fe, Cu, Zn, B and heavy metals (Pb, Cd, Hg, Ni, Se, Sn) and metalloid (As). There was a wide variation of metal contents among the tea leaves coming from… CONTINUE READING
