526例儿童指血微量元素检测结果分析

为了解吐哈油区婴幼儿体内钙、铁、锌、铜、镁的含量,使用多通道原子吸收光谱仪对门诊体查的526例0~7岁幼儿指血检测了钙、铁、锌、铜、镁。结果表明,各个年龄组中缺铁均居第一位,缺钙居第二位,缺锌居第三位,年龄越小,这3种元素含量越低。提示婴幼儿生长发育快,易缺钙,铁,锌元素,年龄越小,越易缺乏。     

非育珠背角无齿蚌软组织微量元素含量的分析

采用高频电感耦合等离子体发射光谱(ICP—AES)法测定了非育珠背角无齿蚌软组织中锰(Mn)、铁(Fe)、锌(Zn)、铬(Cr)、铝(Aj)、铜(Cu)六种微量元素及钙(Ca)、镁(Mg)的含量，分析了各种元素在不同软组织中的分布特征。结果表明：(1)在软组织中，各元素平均含量由高到低依次为：Ca，Mn，Mg，Fe，Zn，Al，Cr，Cu；(2)背角无齿蚌不同软组织中微量元素的含量不同，其中瓣鳃和外套膜中所测元素含量高于其他器官，特别是Mn，Fe的含量最高；Mn的含量甚至超过了宏量元素Mg；Al是闭壳肌中含量最丰富的微量元素。     

Mineral Contents of Jerusalem Artichoke (Helianthus tuberosus L.) Growing Wild in Turkey

Macro- and micro-elements of Jerusalem artichoke (Helianthus tuberosus L.) tubers growing in Konya (Karap?nar and Çumra locations) provinces in Turkey were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Potassium, phosphorus, magnesium, and calcium contents of Jerusalem artichoke were found at high levels, whereas K content was found as 21615 mg/kg and 26251 mg/kg for Jerusalem artichoke; P contents of Jerusalem artichoke were found between 2585 and 4791 mg/kg; and Ca was determined between 1573 and 2073 mg/kg for Jerusalem artichoke. In addition, Zn content was found in a range from 11.0 mg/kg for Yaylap?nar to 15.6 mg/kg for Saraco?lu artichoke. While Fe content of Jerusalem artichoke was found between 23.32 mg/kg to 54.46 mg/kg, Cu content of Jerusalem artichoke was determined between 4.50 mg/kg to 8.98 mg/kg. The Cr contents of Jerusalem artichoke were found between 0.396 mg/kg to 0.642 mg/kg. Ash contents of Jerusalem artichoke tubers were found between 5.70% to 7.63%. Protein contents of Jerusalem artichoke samples were found between 6.23% to 10.71%.
