Monitoring of metal and metalloid content in dietary supplements on the Croatian market

摘要: Thirty samples of widely used vitamins and herbal preparations distributed on the Croatian market were analysed by atomic absorption spectrometry in order to estimate contamination with Pb, Cd, As, Hg, Cr, Ni Zn due their potential toxicity if present above maximum allowable levels (MAL). The following concentration ranges obtained (in g g-1): Pb 0.25-3.86 ; Cd 0.05-0.28 As 0.10-0.19 Hg 0.02-0.12 Cr 0.11-64.38 0.24-338.90 1.00-95.3. Several formulations had metal limits (Pb: one honey-based product medicinal herb-based Cr: containing Ni: two products animal origin). Moreover, estimated cumulative daily intakes several metals from some dietary supplements higher than oral permitted exposures set USP Advisory Panel impurities minerals Such a significant additional source human diet, therefore could be harmful for health.
