SELECTED TRACE ELEMENTS IN THE HUMAN BODY

Abstract

In scientific publications on human nutrition the definition of ?trace elements? concerns these elements, which occurs in the body tissue in very small amounts, regardless of they are essential or not In other words, it will be these chemical elements, which exist in the body or they are required for proper functioning of an organism and are characterized by low concentration. In this manuscript we focused on a number of elements, which may induce disturbances in functioning of many life processes when they are in excess. We chose iron, zinc, copper, chromium, nickel, arsenic, mercury, cadmium and lead for showing the possible role of trace elements in causing diseases, including cancers.
