All of the elements, except mercury were determined in the homogenates of carcasses and organs, which were dried at 85° following the mineralization of samples by concentrated HNO3 of High Purity grade, according to GOST 26929-94 on the atomic absorption spectrophotometer Shimadzu AA 6800. The element identification accuracy as well as the possible contamination of samples in the analysis were controlled according to the four calibration solutions, including the baseline (zero) solution. Statistical data processing was performed using the standard Excel software. The results were recalculated to wet weight.
