Zinc levels were determined in human milk and umbilical cord blood samples collected in the Rijeka Clinical Hospital during the period from September 1995 to January 1996. The average concentrations of zinc were 4.98 +/- 2.53 mg/l in breast milk (range: 1.69-11.60 mg/l) and 1.18 +/- 0.21 mg/l in umbilical cord blood (range: 0.87-1.91 mg/l). Results of group comparisons regarding mothers' age, parity, residence and smoking habits indicate that parity affected Zn levels in both, breast milk and umbilical cord blood, with higher content found in primiparae. Younger mothers (aged < or = 25 years) also had higher levels of Zn in breast milk compared to those whose age was > 25 years. Residence and smoking habits did not seem to have any impact on Zn concentrations in biological tissues studied. A weak association between umbilical cord blood Zn levels and anthropometric measurements of newborns, like birthweight and head circumference, is also observed.
1995年9月至1996年1月期间，在里耶卡临床医院采集了人乳和脐带血样本，测定其中的锌含量。母乳中锌的平均浓度为4.98±2.53毫克/升（范围：1.69 - 11.60毫克/升），脐带血中锌的平均浓度为1.18±0.21毫克/升（范围：0.87 - 1.91毫克/升）。关于母亲年龄、胎次、居住地和吸烟习惯的组间比较结果表明，胎次会影响母乳和脐带血中的锌含量，初产妇的锌含量更高。与年龄大于25岁的母亲相比，年龄小于或等于25岁的年轻母亲母乳中的锌含量也更高。居住地和吸烟习惯似乎对所研究生物组织中的锌浓度没有任何影响。还观察到脐带血锌水平与新生儿人体测量指标（如出生体重和头围）之间存在微弱关联。
