Abstract

SELECTED TRACE ELEMENTS IN THE HUMAN BODY S u m m a r yIn 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.

Awareness of parents of preschool children about selected heavy metals in food

“…Some elements do not perform biological functions in the human body and can cause negative health effects even at low concentrations. The most toxic heavy metals include cadmium, lead, and mercury, which enter the human body primarily through the consumption of foods contaminated with them, through the digestive tract [7,8]. Exposure to heavy metals through oral, dermal, respiratory, and non-dietary way is a significant risk factor for the health of adults and children, resulting, among others, from the durability of heavy metals in the environment and their ability to accumulate, as well as carcinogenic properties [3,9].…”

Copper and Zinc as Potential Biomarkers of Mood Disorders and Pandemic Syndrome

“…Copper (Cu) and zinc (Zn) are among the 11 trace elements meaningful to human health [ 8 ]. Both of these microelements participate in many physiological processes that are crucial in the etiology of mental disorders.…”
