XENOBIOTICS AND BIOGENIC ELEMENTS IN RAW COW'S MILK

This paper presents the concentration some toxic and biogenic elements in milk from Nitra region. The aim of this investigation was to evaluate 30 samples of raw milk with fat contents 3.8% obtained from milk machine in the Nitra region. Samples were analyzed for metal contents using atomic absorption spectrophotometry (AAS). In comparison with maximum acceptable concentration for milk in the food codex of the Slovak republic, the level of contamination with cadmium was exceeded and reached the value 0.221 µg.ml-1. The copper content ranged from 1.201 µg.ml-1 to 5.810 µg.ml-1 and the average concentration reached 3.793 µg.ml-1. Iron had an average of 1.824 µg.ml-1. Overall in all milk samples high correlations were found. Between positive correlation (0.7019) and negative correlation between of nickel and potassium concentration in raw milk (-0.72) was found. doi:10.5219/246
