Abstract
In this work we monitored the contents of the microelements (Zn, Cu, Mn, Co, Pb and Cd) in cattle and pig livers and spleens. Samples were analysed at the slaughter-houses in Ratina for one year from 19. 11. 1985 to 2. 11. 1986. The cattle and pigs used in the investigation came from the Kraljevo region. Sampling was properly divided according to the seasons of the year and the total analysed by 12 samples of each confiscate, that is by 3 confiscates in each yearly season.
Results on the contents of Zn, Cu, Mn, Co, Pb and Cd were achieved by tie application of atomic-absorption spectrophotometry.
Results of our investigations of concentrations of Cu, Mn, Zn, Co, Pb and Cd showed variations regardless of the time of the year.
In all samples Co was below the limit of detection, while the presence of Cd was proved only in samples of the cattle livers sampled in the spring season. Copper was, in a high concentration, present in the livers of the cattle and pigs compared to the spleens.
