The article presents studies of the microelement status of welders. The imbalance of macro-and microelements in noninvasive biological substrates of welders in comparison with the control group has been defined. It was found a positive correlation between the content of Cd, Fe, Cr, Mn in non-invasive and invasive biosubstrates. The analysis of relationships between essential elements in some cases showed their non-conformity with physiological norms.
