Trace elements content Cd, As, Hg, Pb, Ni, Cr, Fe, Cu, Zn, Co and Mn in the single steps of virgin sunflower oil production were studied. It was determined that mercury is cumulated in sunflower kernel and passes into oil. Chromium is concentrated in sunflower hulls and therefore is not passing into oil. Nickel, iron, copper, cobalt, manganese remained in pressed sunflower meal. Only their decreased content was found in oil because mechanical purifying (separation and filtration) minimized their content. We determined the levels of selected trace elements in sunflower virgin oils produced in Slovakia in 1995 and 1996. Methods of atomic absorption spectrometry using graphite furnace and flame were used.
