Reference intervals of essential and toxic elements concentrations in mane hair and blood serum of Arabian purebred horses

Abstract

The article presents the results of studies on the establishment of reference intervals of concentrations of the main essential and toxic elements in mane hair and blood serum of Arabian purebred horse stallions, calculated by Atomic emission spectroscopy (AES) and Inductively coupled plasma mass spectrometry (ICP-MS) methods. For mane hair, these values are Ca 81,28-1875; K 57,2-2134; Mg 93,92-1154; Na 16,76-542; P 47,1-827,3; Co 0,008-0,201; Cr 0,022-1,35; Cu 0,936-9,73; Fe 18,55-363; I 0,006-0,367; Mn 0,407-8,34; Se 0,039-0,625; Zn 14,49-201; B 0,311-25,66; Li 0,027-0,82; Ni 0,05-0,712; Si 0,809-34; V 0,018-0,594; Al 5,98-208; As 0,009-0,116; Cd 0,001-0,021; Hg 0,002-0,008; Pb 0,02-0,571; Sn 0,001-0,097; Sr 0,311-5,94. For blood serum, these values are Ca 106,2-161,3; K 89,19-187,1; Mg 18,16-27,05; P 78,32-153,1; Co 0,0003-0,0015; Cr 0,0003-0,0101; Cu 0,7-1,46; Fe 1,35-3,51; Mn 0,0005-0,0043; I 0,007-0,019; Se 0,118-0,208; Zn 0,502-0,952; Al 0,01-0,028; As 0,001-0,004; Cd 0-0,0001; Hg 0,0002-0,0009; Pb 0,0001-0,0026; Sn 0-0,0001; Sr 0,14-0,367. It was found that the chemical elements concentration in hair is significantly higher (1.4-2707 times) compared to blood serum; it makes this biosubstrate more informative for the elemental status evaluation. The results of the correlation analysis indicate the absence of a reliable correlation between the content of the studied elements in hair and blood serum.
