Description
Summary:Current capabilities of the nuclear and related analytical techniques: neutron activation analysis, X-ray fluorescent analysis, and atomic adsorption spectrometry—are used to carry out multielement analysis of a wide range of foodstuffs and drinking water in various regions of Russia. The results of a more than 20-year-long collaboration of the Geological Institute, Russian Academy of Sciences, and the Neutron Activation Analysis and Applied Research Sector, Frank Laboratory of Neutron Physics, Joint Institute for Nuclear Research, in this field are presented. It is shown that the trace element content of agricultural products depends on the ecological and geochemical conditions in a particular region. A possibility of lettuce and spinach variety determination with respect to Cd and Pb contamination of the soil is demonstrated in the experiment with artificially produced soil contamination. Principles that may underlie accumulation of heavy metals and toxic elements by basidiomycetes are determined. Out of a great deal of human diets in use, the six most typical ones are selected and the intake of macro- and micronutrients from these diets by a human is evaluated. The effect produced on the human organism by the basic elements intake with the food and possible risks are discussed. Dependence of the trace element content of the drinking water on the ecological and geochemical conditions is investigated in three regions of Russia. It is shown that the quality of drinking water critically depends on the condition of the water supply system.
