APPLICABILITY OF NEUTRON-ACTIVATION ANALYSIS (NAA) IN QUANTITATIVE-DETERMINATION OF SOME ESSENTIAL AND TOXIC TRACE-ELEMENTS IN FOOD ARTICLES

Accurate and reliable data on microgram and nanogram quantities of som e essential and toxic elements in most food articles are very scarce. Neutron activation analysis (NAA), with its essentially blank-free adv antage, is a valuable approach in the field of determination of trace elements in different foodstuffs and diets. Accordingly, various radio chemical (RNAA) and instrumental (INAA) approaches have been developed in our laboratory for the elements As, Cd, Co, Cu, Hg, I, Mo, Ni, Sb, Se, Sn, Th, U, V, and others, and verified by the analysis of composi tionally appropriate certified reference materials.
