title: The analysis of plant-based raw materials of unknown origin.
abstract: Chosen aspects of the safety of use of several herbs received from National Medicines Institute, which came from smuggling, have been examined. The analysis has been conducted in three different aspects: (1) Possibilities of contamination of plant-based raw materials by metals of heavy elements (As, Cd, Cu, Cr, Pb). (2) Conscious smuggling of intoxicating preparation or narcotics in plant-based raw materials. (3) Radioactive contamination originating mostly from 137Cs isotope. To solve the problem, analytical methods of GFAAS and ICP-MS, X-ray diffraction and high-distributive spectrometry of gamma-radiation have been applied. Determined concentration of arsenic in all analyzed samples and the concentration of lead in one sample exceeded allowable concentration recommended by WHO. In analyzed materials, no presence of narcotics or radioactive contamination of 137Cs isotope has been detected.
