Biography:

Vladimir Zaichick is a Nuclear Physicist, Biologist and Researcher. He obtained his MS in 1966 from the Moscow Institute of Engineering Physics, his PhD (nuclear physics) in 1972 from the Institute of Biophysics, Moscow, and his DSc (radiobiology) in 2011 from Medical Radiological Research Center, Obninsk, Russia. He is a full professor of radiobiology, a fellow of the British Royal Society of Chemistry (FRSC) and a Chartered Chemist (CChem) since 1996. He has made 141 presentations at seminars and conferences, published more 300 papers in reputed journals and is serving as an editorial board member of four scientific journals.        

Abstract:

Since the times of the alchemists, chemical elements have been investigated in human organs, tissues and fluids. During the last decades the number of publications devoted to them increased considerably. Today, the number of published articles may be estimated at about twenty thousands, and the amount of monographs about hundred. This vast amount of data, dealing with the importance of elements acquired in different fields of scientific research and practical life, puts forward the need for a synthetic approach in element research. At the end of the 20^th century, a new scientific discipline appeared, focused on the role of chemical elements in human body under physiological and pathological conditions. This new field of interdisciplinary study has been named: “Medical Elementology” (from lat. “medicina” and “elementum”). A lot of medical doctors, toxicologist, ecologist, chemists and physicist who were involved in the study of chemical elements in medicine and biology had thus the feeling that they were working in new self-sufficient scientific sphere. As a rule, all scientific disciplines are characterized, first of all: 1) by the subject of study; 2) by accepted postulates; 3) by research methods; 4) by methods of quality control; 5) by terms and definitions. Instrumental analytical methods such as non-destructive NAA and EDXRF as well as destructive AAS, ICP-AES and ICP-MS are the main research instruments in Medical Elementology. Role and place of ICP-MS will be discussed using our results obtained in the age-dependence studies of 67 chemical element contents in human bone, hair and prostate gland.
