Environmental Application


There has been an increasing awareness conceming the adequacy of trace elements in diet as their deficiency or excess may cause abnormal changes in the biochemical processes. Typical Indian vegetarian diet and dietary components such as cereals, grains, pulses, vegetables and spices have been analysed for 19 elements (Br, Cl, Co, Cr, Cu, Fe, Hg, K, Mn, Mo, Na, P, Rb, Sb, Sc, Se, Sr, Th and Zn) by instrumental neutron activation analysis (INAA). Several Standard Reference Materials (SRMs) were analysed for quality assurance. Based on the elemental contents, the daily dietary intake has been calculated and the data compared with those from other countries, Recommended Dietary Allowances (RDAs) and permissible body burden. It has been observed that, although vegetarian, the Indian diet has an adequate content of essential trace elements compared to non-vegetarian oriental (Japan and Taiwan) and western (Germany, Denmark and USA) diets.
