Eleven elements (Cu, Zn, Mn, Fe, K, Ca, Mg, Ni, Cd, Pb and Cr) in seven herbal drugs (Salviae folium, Menthae piperitae folium, Melissae folium, Lavandulae flos, Basilici herba, Marubii herba and Origani herba) and in rhizosphere soil samples were determined. A microwave digestion procedure preceded the measurements by the flame and electrothermal atomic absorption spectroscopy techniques (FAAS, ETAAS). For potentially hazardous elements and their bioavailability, BCF values were also calculated and discussed in order to identify possible sources of specific elements. Određen je sadržaj 11 elemenata (Cu, Zn,Mn, Fe, K, Ca, Mg, Ni, Cd, Pb i Cr) u sedam biljnih droga Salviae folium, Menthae piperitae folium, Melissae folium, Lavandulae flos, Basilici herba, Marubiti herba i Origani herba) kao i u uzorcima zemljišta (rizosfere). Mikrotalasna digestija uzoraka je prethodila određivanju koncentracije elemenata primenom metoda plamene i elektrotermalne atomske apsorpcione spektroskopije. Izračunati su i biokoncentracioni faktori za potencijalno toksične elemente u cilju razmatranja potencijalne bioraspoloživosti, kao i identifikacije mogućih izvora zagađenja. more...
