“…As shown in Table 4, the level of toxic elements in breast milk may vary in different countries and regions [9][10][11][12][13][14][15][16][17][18][19][20]. The values adopted in our study are above the some countries' data in spite of they were not on toxic level.…”

Owing to its unique nutritional and immunological characteristics, breast milk is the most important food source for infants. But, children are at greater risk for exposure to environmental toxicants from breast milk. The aim of this study was to evaluate the influence of environmental pollution on essential and toxic element contents of breast milk and determine the risky locations in our population. This study was conducted on women who were breastfeeding (n=90). Milk samples were collected at three locations in Marmara region, Turkey: highly industrialized region highly affected by pollution, urbanized region moderately and rural area that is affected little. Breast milk samples (5 mL) were collected at approximately one month postpartum (mature milk). The concentrations of cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn) in milk samples were compared to the milk samples coming from different locations. Lead, cadmium, nickel, chromium, iron and manganese levels in the breast milk are highest and engrossing especially in rural areas compared to the other regions but cobalt, copper, zinc levels are highest in highly industrial areas. The levels of essential and toxic elements in breast milk can vary in different regions. The levels presented in our study are above some countries' data albeit not at toxic levels. Because of global effects, environmental pollution is not the problem for industrializing regions only. Rural area also may not be safe for breastfeed babies.

“…On the other hand, some authors found different concentrations. For example, Krelowska-Kulas et al [24] found 1,000-1,900 μg/kg, Elmastas et al [25] found 5,150± 13 μg/l, Lopez et al [26] found 487±88 μg/kg, and Aganga et al [27] found during goat's lactation average concentrations from 6,890±740 to 8,780±90 μg/l. The cause of these differences can be due to different goat breeds and countries in which the experiments were realized.…”

The aim of the experiment was to study zinc concentration in goat's milk during a short-term oral supplementation of three organic and one inorganic form of zinc and the influence of Zn supplementation on the concentration of Zn and Cu in blood plasma. The experiment involved 31 lactating goats. The group C was the control, group L received zinc lactate, group A received zinc chelate, group T received amino acid-polypeptidic complex with zinc, and group O received zinc oxide. Zinc preparations were administered orally in 500 mg Zn per animal for 28 days. In the course of the experiment, Zn concentration in plasma increased significantly in all experimental groups and in the control group was unchanged. The concentration of zinc in milk during the experiment fluctuated in individual groups, but there were no significant differences between groups. After 28 days of Zn supplementation, Zn concentration in milk of goats was similar as at the start of the experiment in all groups. According to our results, the supplementation of different forms of zinc did not influence the concentration of Zn in milk, but significantly influenced the Zn concentration in blood plasma. The efficiency of different organic and inorganic forms of zinc was similar.

“…The mineral content of the most commonly consumed milk, bovine milk, has been determined and verified (Cava-Montesinos et al, 2005;Coni et al, 1995;Elmastas et al, 2005;Licata et al, 2004). The nutritive value of goat milk has also been established (Aganga et al, 2002;Coni et al, 1996;Elmastas et al, 2005;Park, 2000;Rodrígez Rodrígez et al, 1999b), and the quality of sheep milk was investigated by Aganga et al (2002), Coni et al (1996), and Elmastas et al (2005).…”

“…Human milk samples from all over the world, including Brazil (Goes et al, 2002;Morgano et al, 2005), Japan (Yamawaki et al, 2005) and Spain (Ló pez-Ló pez et al, 2002), were analyzed. The contents of macronutrients, such as fat, protein, carbohydrates and trace elements in human milk were determined Elmastas et al, 2005;Sam et al, 1998). Furthermore, the identification of chemical species and element quantification in various milk fractions was conducted Coni et al, 2000;Goes et al, 2002).…”
