“…It is therefore important to monitor the levels of trace elements in cow's milk, which forms a major source of nutrition in childhood, consumed with breakfast cereals and as yoghurt or cheese. The concentrations of selected trace elements such as Al, Ba, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Pt, Sr and Zn in raw cow's milk and cheese were determined using inductively coupled plasma-optical emission spectrometry after lyophilisation followed by ashing (Coni, Bocca, Ianni, & Caroli, 1995;Coni, Caroli, Ianni, & Bocca, 1994). Coni et al (1996) later assessed the concentrations of the same elements in sheep and goats milk as well as in cheese employing the same method.…”

The levels of trace elements are an important component of safety and quality of milk. While certain elements such as chromium are essential at low levels, an excess can result in deleterious effects on human health. International quality control standards for milk are published by the Codex Alimentarious Commission and levels of heavy metals in milk intended for human consumption are routinely monitored. This paper describes a new method for demonstrating the levels of V, Cr, Mn, Sr, Cd and Pb in raw cow's milk, using an ICP-MS. Samples (n = 24) of raw cow's milk were collected from dairy farms close to mines in Gauteng and North West Provinces of South Africa. In order to destroy organic matrix, each freeze dried milk sample was mineralised by using a microwave assisted digestion procedure. Concentrations of trace elements in digested milk samples were measured by ICP-MS. A whole milk powder reference material (NIST SRM 8435) was used to evaluate the accuracy of the proposed method. It was found that the levels of V, Cr, Mn, Sr, Cd and Pb obtained using the new method showed concordance with certified values.

“…It is also known that metal (Cd, Pb and Hg) (Oskarsson et al, 1995). Concentrations of heavy metals in milk were mainly described in cows (Coni et al, 1994;Kottferová and Koréneková, 1995;Tahvonen and Kumpulainen, 1995;Okada et al, 1997;Rosas et al, 1999;Cerkvenik et al, 2000;Simsek et al, 2000;Pilsbacher and Grubhofer, 2002;Sikirić et al, 2003), goats (Lopez et al, 1985;Anke et al, 1990Anke et al, , 1996Krelowska-Kulas et al, 1999;Milhaud et al, 2000;Hejtmankova et al, 2002) and very scarcely in ewes Mehennaoui et al, 1997Mehennaoui et al, , 1999Milhaud et al, 1998). The objective of this investigation was to determine heavy metal concentrations in ewe milk and their fluctuations depending on lactation stage.…”

ABSTRACT:Biological investigations on ewes of Merinolandschaf breed (n = 10) were conducted by the 60 th lactation day during the summer on pasture. Ewe milk sampling was carried out on the 2 nd ; 10 th ; 30 th and 60 th lactationday. An electrothermal technique was used to determine Cd and Pb concentrations in food and milk whereas As and Hg concentrations in food and milk were determined by a hydrid technique on an atomic absorption spectrophotometer. The investigation results indicate that concentrations of selected toxic elements in ewe milk varied in dependence on lactation stage. In colostrum (2 nd lactation day) Cd and Pb (0.011 and 0.035 mg/kg) concentrations were significantly higher (P < 0.01) whereas As (0.011 mg/kg) concentrations were lower in comparison with milk on the 10 th (Cd: 0.004; Pb: 0.022; As: 0.025 mg/kg), 30 th (Cd: 0.005; Pb: 0.024; As: 0.028 mg/kg) and 60 th (Cd: 0.006; Pb: 0.026; As: 0.029 mg/kg) lactation day. However, no significant differences (P > 0.05) were found in milk Hg concentration in relation to lactation stage (from 0.021 to 0.026 mg/kg). The selected toxic elements appeared to be present in ewe milk in very low concentrations.
