Trace elements in the onion originated from the Tikves area (Republic of Macedonia)

The paper presents the geochemical research for the presence of trace elements in onion produced in the Tikvesh area, Republic of Macedonia. The conducted research is made by the application of the method ICP-AES, ICP-MS. The following results for the presence of the trace elements are obtained: Li (0.037 ppm) ; B (8 ppm) ; Na (43 ppm) ; Mg (841 ppm) ; Al (17 ppm) ; P (2352 ppm) ; Ca (3747 ppm) ; Ti (5.1 ppm) ; As (0.033 ppm) ; Sr (23 ppm) ; Mo (0.457 ppm) ; Cd (0.043 ppm) ; Sb (0.008 ppm) ; Cs (0.018 ppm) ; Ba (18.5 ppm) ; Pb (0.348 ppm) ; V (0.040 ppm) ; Cr (0.848 ppm) ; Mn (9.2 ppm) ; Fe (148 ppm) ; Co (0.037 ppm) ; Ni (1.44 ppm) ; Cu (2.15 ppm), Zn (13 ppm) ; Ga (0.388 ppm).
