Traces of cadmium, lead and copper in infusion and eating medicinal herb samples collected from Libya were determined by differential pulse anodic stripping voltammetry as well as atomic absorption spectrometry. The statistical parameters i.e. slope; standard deviation, correlation coefficient and confidence have been calculated. The levels of Cd(II), Pb(II) and Cu(II) in infusion and eating samples was obtained using stripping voltammetry ranged from 0.064 to 0.146 and 0.034 to 0.271 for cadmium, 0.874 to 3.020 and 0.332 to 2.263 for lead and 0.384 to 1.280 and 0.490 to 1.468 μg g−1 for copper respectively. Copper concentration in infusion and eating samples was determined by flame atomic absorption spectrometry (FAAS) and the concentration level was ranged from 0.395 to1.360 and 0.495 to1.420 μg g−1 respectively. On the other hand, the levels obtained for cadmium and lead in infusion and eating samples by graphite furnace atomic absorption spectrometry (GFAAS) ranged from 0.065 to 0.150 and 0.034 to 0.253 for cadmium and from 0.910 to 3.050 and 0.335 to 2.250 μg g−1 for lead respectively. The results also indicate that, cadmium , lead and copper contents in all samples are less than that permissible values which given by WHO and FAO. |
