Maternal breast milk is a unique biological matrix that contains essential micronutrients. Potentially heavy metals may also affect infants' health and growth through maternal breast milk. 'I he purpose of this study was to determine and compare the essential elements and heavy metals of maternal breast milk of nursery mothers residing in sanhurfa province, Turkey. Maternal breast milk concentrations of sodium, magnesium, phosphorus, potassium, calcium, iron, copper, zinc, arsenic, and lead were analyzed in a random sample of the first time in urban and suburban nursery Turkish mothers (n: 42). Eight essential elements and two heavy metals were analyzed using ICP-MS after microwave digestion. For bivariate analyses of variables, we use nonparametric Speannan's correlation coefficient test. The mean concentrations of essential elements and heavy metals were as follows: sodium 330 +/- 417 mg/L, magnesium 32.6 +/- 15.5 mg/L, phosphorus 156 +/- 46.2 mg/L, potassium 488 +/- 146 mg/L, calcium 193 +/- 53.2 mg/L, iron 1.65 +/- 1.43 mg/L, copper 0.54 +/- 0.46 mg/L, zinc 2.89 +/- 3.23 mg/L, arsenic < 1 mu g/L, and lead < 1 mu g/L. Concentrations of heavy metals in maternal breast milk may have the important implication that it is not affected by environmental pollution in this province. This study provides reliable information about maternal breast milk concentrations of nursery mothers residing in sanhurfa, Turkey, and also compares the relations between essential elements and socioeconomic conditions, residing areas, and using copper equipment for food preparation of which some have not previously been reported.
