Metals in Finnish liqueurs.
The metal content of some representative Finnish berry liqueurs was determined by atomic absorption spectrometry. The berry liqueurs were prepared from cloudberry (Rubus chamaemorus), arctic bramble (Rubus arcticus), cranberry (Vaccinum oxycoccus), lingonberry (Vaccinum vitis-idaea) and sea buckthorn (Hippophae rhamnoides). In addition some other Finnish berry, fruit and herbal liqueurs were analyzed. The trace elements studied were Al, As, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Rb, and Zn. The level of poisonous metals in all the samples was very low: As less than 0.1, Cd less than 0.005 and Pb less than or equal to 0.1 mg/l.
