title: Effect of long-term geomagnetic field deprivation on the concentration of some elements in the hair of laboratory rats.
abstract: The aim of the study was to determine the effect of long-term geomagnetic field (GMF) deprivation on the concentration of selected elements in the hair of laboratory rats. A total of 32 Wistar laboratory rats were divided into four equal groups (males and females) kept under hypomagnetic conditions (GMF vertical component below 20nT) and two control groups (males and females) kept free of field disturbances (GMF vertical component approx. 38000nT). At the beginning and at 7 months of the experiment, hair was taken from the dorsal part of all rats and analysed using atomic emission spectrometry for the concentration of selected magnetic elements (Fe, Ni, Co, Cr, Mn and Cu). Long-term GMF deprivation was found to affect the concentration of Fe, Mn, Cu and Cr, but had no significant effect on the concentration of Co or Ni in the hair of the analysed rats.
