VARIABILITY OF MICROELEMENT CONTENTS IN LIVER AND MUSCLES OF DIFFERENT PHEASANT SPECIES

Abstract

The lack of data on accumulation and distribution of chemical elements in body organs of decorative birds in Ivanovo has moved us to find the specifics of microelements concentration in the livers and mus-cles of decorative pheasants of different species. The presence of microelements was researched by using the Kvant-2А spectrophotometer, with ashing of samples going according to GOST 30178-96. From the total accumulation of microelements in question, the amount of Fe and Zn in the liver makes up 92,6-28,7%, and 71,4-96,7% in the muscles. The amount of Fe in the liver of Phasianus colchicus is 2,1-4,4 times higher than of other species of pheasants, and the amount of Fe in the muscles of Tragopan satyra is 2,6-4,2 times higher than of other species of pheasants. In the pheasants` livers the diapason of Zn con-tent did not exceed 38%, with the muscles of Phasianus colchicus having 6,3-7,3 times the amount of Zn in comparison to other species. The amount of Cu in the liver and muscles of Lophura leucomelanos is higher in comparison with other birds. For Syrmaticus ellioti, the liver contains 4,2-6,9 times less Mn, but they have 1,9-3,8 times more Mn in their muscles than other pheasants. The amount of Ni in the pheasants` livers is located in the diapason of 0,12-0,59 mg/kg, and 0,25-0,47 mg/kg in the muscles. The accumulation of Pb in the muscles is 0,25-0,47 mg/kg, with livers of Tragopan satyra and Syrmaticus el-lioti having 0,55 and 0,74 mg/kg. The concentration of Co in the pheasants’ muscles turned out to be 0,007-0,011 mg/kg, with 0,011-0,035 mg/kg in the livers. In the muscles and livers of Lophura leuco-melanos the levels of Cadmium are lower by 58,3-82,1% and 51,8-78,8% accordingly, in comparison to other species of pheasants. Therefore, species-specific tendencies of pollutants accumulation are noted. Were noted higher concentrations of Fe and Pb in the muscles and Mn and Ni in the livers of Phasianus colchicus; Cu in the muscles and livers of Lophura leucomelanos; Mn, Co and Cd in the muscles and Pb in the livers of Syrmaticus ellioti. No pattern in the microelement distribution in the livers and muscles was noted.
