“…Figure 1 shows the evolution of Fe, Cu and Zn mean concentrations in deviation in human milk with the stage of lactation. This behaviour is in agreement with other authors (Arnaud et al, 1991;Bates & Tsuchiya, 1990;Casey et al, 1989;Higashi et al, 1982;Karra et al, 1986Kirksey et al, 1979;Krebs et al, 1985a;Moser & Reynolds, 1983;Rajalakshmi & Srikantia, 1980;Schramel et al, 1988;Sievers et al, 1992;Suzuki et al, 1991;Vaughan et al, 1979;Vuori & Kuitunen, 1979;Vuori et al, 1980). The Cu concentration also decreased progressively from the 2nd week (0.528 ± 0.084 mg Cu/l) until the end of the sampling period (0.117 ± 0.023 mg Cu/l), which agrees with most authors (Benemariya et al, 1995;Casey et al, 1985Casey et al, , 1989Suzuki et al, 1991;Vuori & Kuitunen, 1979).…”
