The results of the atomic absorption analysis of the elemental status of pigs of Kemerovo breed are presented. The studies were carried out in pig farm in Kuzbass. Organ samples from pigs were taken immediately after slaughter and analyzed at the Analytical Center for Collective Use of the Sobolev Institute of Geology and Mineralogy (ACCU Sobolev IGM SB RAS) by atomic absorption spectrometry with flame and electrothermal atomization using SOLAAR M6 spectrometer (USA) according to State Standard 26929-94 “Raw food and food products. Cadmium levels in bristles (W=0.94, p>0.05) and kidneys (W=0.92, p>0.05) were characterized by normal distribution. In the breeding zone of the Kemerovo breed, the content of heavy metals in soil, water and feed was studied, which did not exceed the MPC. The mean cadmium levels in the kidneys and spleen were within the standard intervals established for pigs. Cadmium levels in the spleen and bristle were characterized by a smaller interquartile range relative to the kidneys. The obtained data on the concentration of cadmium in the organs and bristles of pigs of the Kemerovo breed can be used for the intravital assessment of the interior of animals. |
