“…Concentrations of most of the microelements and toxic elements (Cr, Co, Mo, Ni and Hg) in milk significantly differed according to determined high standard deviation, that could be related to low concentrations and low level of instrumental detection limit (Table 1 and Mentioned significant increase of Cd and nonsignificant concentrations of Cr and As, as well as non-significant decrease of Pb and Hg concentrations during lactation mostly depend on feed or water intake, and possible consumption of soil (Ghidini et al, 2012). In general, sheep´s milk contains very low concentrations of heavy metals (Antunovic et al, 2005).…”

The aim of the present study was to determine the lactation stage effect on the concentration of essential and selected toxic elements in the sheep's milk of Dubrovačka ruda. The research was conducted with 23 sheep, average age of 4 years, of 3 rd lactation, while the milk samples were taken during the early (60 th day), middle (90 th day) and late (120 th day) lactation stage. The sheep were selected according to uniformed body development, adequate health status, body condition, equable age (4 years), parity (3 rd lactation), stage of lactation (±7 days) and litter size (single). Sheep were reared on the extensive Mediterranean pastures, reared indoors afterwards, fed with hay ad libitum and feed mixtures in average 0.5 kg/day. Milk sample was collected during morning milking from each sheep. The digested samples were analyzed with continuous flow hydride generation technique using inductively coupled plasma for Ca, Mg, K, P, Na, Cu, Fe, Zn, Mn, Ni, Mo, Co, Cr, Cd and Pb concentrations. Significant increase of Mg, Na, Se, Mn, Mo and Cd concentrations were found in milk as well as decrease of K concentration during the lactation. Although the concentration of Ca, Cu, Cr and As in milk during the lactation is increased, the differences between the lactation stages were not observed. Concentrations of P, Fe, Ni, Pb and Hg in milk of Dubrovačka ruda did not differ during the lactation. The low concentrations of Cr, Cd, Pb, As, Hg in milk indicate the safety for consumers and preserved environment of Dubrovnik-Neretva County.
