This work evaluated the concentration of minerals in milks which are donated to the Bank of Milk of Amapa State, bymeans of the technique of atomic absorption, with the aim to argue for the importance of this analysis in the routine ofBanks of Milk do as to help in therapeutic treatments of newborn babies who have lack of some minerals. After quantifyingthese levels, the milk could have been used for therapeutic treatments for infants who have a certain mineral deficiency.Quantitative analysis of the elements presents in milk focused on Ca, Cu, Zn, Mg, Mn, Na, Cd, Fe, Pb and K. These elementswere chosen because of their importance and nutritional value for absorption by newborns, as well as those thatmay cause acute intoxication, for example, Cd and Pb, which are common at low levels in certain foods and drinks. Forexample, in a milk sample a content of 1 ppm Cd was found, thereby being an average value of contamination. The resultsof the analysis were divided into 4 zones, representing the collection points in state Amapa. In two zones we observedhigh levels of Mn and Na. And, checking all points of the study, it was found that the tests were satisfactory, particularly asregards comparisons to similar tests for atomic absorption and commercial brands. Anyway, it was observed in this studythat the investigative method of metals in human milk is of paramount importance so as to be recommended as a routinepart of Milk Banks, especially for therapeutic and nutritional ends, by analyzing the quality and quantity of constituentelements of such milks
