Abstract

Leg muscle and liver samples of 25 coypu were used for analysis of mineral content. Total elements content was analyzed by flame atomic absorption spectrometry (FAAS) and electrothermal atomic absorption spectrometry (ETAAS). The content of arsenic was analyzed by hydride generous atomic absorption spec-trometry (HGAAS). Mean values and standard deviations of aluminium (Al), arsen (As), cadmium (Cd), co-balt (Co), chrome (Cr), copper (Cu), iron (Fe), potassium (K), manganese (Mn), molybdenum (Mo), sodium (Na), nickel (Ni), lead (Pb), selenium (Se), strontium (Sr) and zinc (Zn) were calculated. For each mineral the contents in the liver were higher than in the muscle for all animals. The highest average contents had Na (muscle 2227.51 mg/kg, liver 4123.7 mg/kg) and K (muscle 1081.00 mg/kg, liver 3256.06 mg/kg). Zinc had the highest concentration of microelements in muscle, in decreased line follow the means of Fe, Cu, Mn, Se and Ni. The means of trace elements follow with Sr, Cd, Cr, Mo, AI, Co, Pb and As. The medians of the ratio content of liver to content of muscle were for Mn 5, for Mo and Se 4, for Cu and K 3, for Co and Fe 2.5, for the other minerals between 1.2 and 2. It couldn’t be shown a correlation between liver and muscle mineral content. Some statistical significant differences between age and sex of coypu were found. These differences must be interpreted cautiously because of the situation of multiple tests.
