“…It could be due to elaboration processes, or to the expression of the results considering dry weight or reconstituted milk. However, most of the data relative to Cu (Dabeka & McKenzie, 1992;Esteve, 1994;Garg et al, 1993;Johnson & Canfield, 1989;Munro & Sneddon, 1987) are of the same magnitude as those found by us. For the Zn, this variation is also very great, 53.1 ± 3.40 mg/ kg in samples of the India (Garg et al, 1993), up to a mean value of 3.0 ± 1.5 mg/kg for ten infant formulas marketed in Spain (Cabrera et al, 1996).…”

Concentrations of iron, copper and zinc were determined in 56 samples of mature human milk from Canarian women and 5 samples of powdered infant formula. According to the literature our data fall within the normal limits in each kind of milk. The mean concentration of Fe, Cu and Zn of powdered infant formula was significantly higher than those concentrations found in the human milks. Significant differences among the concentrations of the studied metals for the milks of considered mothers were observed. The Fe, Cu and Zn intakes of infants fed with human milk are lower than the requirements recommended by the Food and Nutrition Board (1989). However, the infants fed with powdered infant formula had consumed an adequate intake of Fe and Cu. A progressive decrease of the metal concentrations with the lactation stage was observed. The human milk obtained in spring presented Fe and Zn concentrations lower than in autumn, which could be due to changes in nutritional habits of the mothers. Age of mother and number of previous children seem to influence the Zn and Cu concentrations of human milk.

“…It composes 1.43% to 2.45% of the total mineral mass (ash) of milk [8 -10]. On a dry-matter basis, its concentration ranges from 244 to 469 mg/kg of milk [11][12][13]. During lactation, bone is mobilized and exerts a marked influence on the availability of those macroelements to the mineral pool that must supply the mammary gland.…”

Reported concentrations for magnesium in breast milk vary over a wide range (15 to 64 mg/L) with a median value of 31 mg/L and 75% of reported mean concentrations below 35 mg/L. Constitutional variables such as adolescent motherhood, gestation length, maternal undernutrition, metabolic disorders (diabetes, galactosemia), race, stage of lactation, sampling techniques (foremilk and hindmilk), as well as environmental variables such as socio-cultural diversity, smoking habits, dietary calcium and magnesium (including supplementation), vegetarianism, calciotropic agents (immunoreactive calcitonin, vitamin D), medication (hormonal contraceptives, magnesium sulfate) are critically reviewed in relation to changes in milk magnesium concentrations. Magnesium secretion into breast milk does not seem to be affected by the studied variables.

“…The method has been used for analyzing different kinds of plants and plant's organs [1][2][3][4][5][6], milk samples from different origins [7][8][9], samples of nutrient and foodstuffs [10][11][12] for environmental studies [13]. Little work has been carried out on the use of INAA for analysis of cosmetics products [14][15][16].…”

Instrumental neutron activation analysis (INAA) has been used to determine some trace, minor and major elements in some cosmetic samples. These samples have been randomly selected from the Egyptian market. Some of these cosmetics are imported from the world market and the others are manufactured in Egypt. Up to 25 elements have been quantitatively determined in selected cosmetic samples. These elements are: As,
