使用电感耦合等离子体原子发射光谱(ICP-AES)和原子荧光光谱法(AFS)分别对内蒙古自治区兴和县180名农村育龄妇女头发中21种矿物元素(铝,硼,钡,钙,镉,钴,铬,铜,铁,镁,锰,钼,镍,铅,硒,硅,锡,锶,钛,钒和锌)的含量及年龄、生育史及饮食习惯等对其产生的影响进行了研究。结果表明,大多数矿物元素(硼,镉,铬,钴,铜,铁,镁,锰,钼,镍,铅,硒,硅,锡,锶,钛,钒和锌)含量从青年组(18~29岁)到老年组(40~45岁)依次减少,而中年组(30~39岁)的钙,镁,锰、铅的含量最低。生育二胎的妇女钙,镁,锰,钼,镍,铅,锡,锶和锌含量最低,这可能与生育次数的增加有关,相关性分析证实钙,铅和锡与生育史有显著性相关。此外,饮食习惯也会影响头发中矿物质元素的含量。经常食用酸菜会导致锌,铁,铜,锰,锶含量水平较低,但钼,铅和硒含量水平较高。而且,锌和硒含量随肉类摄入频率增加而增加。规律性摄入蔬菜会增加硅的含量。同时,经常食用水果会增加锰,镍和钛的含量水平。因此,该研究为解决不均衡饮食习惯盛行的农村地区生育和妇女健康提供基础数据和有用的信息。
A total of 21 mineral elements (aluminum, boron, barium, calcium, cadmium, calcium and magnesium) in hair of 180 rural women of childbearing age in Xinghe County of Inner Mongolia Autonomous Region were analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES) and atomic fluorescence spectrometry (AFS) The influence of the content, age, birth history and dietary habit of cobalt, chromium, copper, iron, magnesium, manganese, molybdenum, nickel, lead, selenium, silicon, tin, strontium, titanium, vanadium and zinc the study. The results showed that the contents of most mineral elements (boron, cadmium, chromium, cobalt, copper, iron, magnesium, manganese, molybdenum, nickel, lead, selenium, silicon, tin, strontium, titanium, vanadium and zinc) ~ 29 years old) to the aged group (40 ~ 45 years old), while the middle aged group (30 ~ 39 years old) had the lowest contents of calcium, magnesium, manganese and lead. The lowest levels of calcium, magnesium, manganese, molybdenum, nickel, lead, tin, strontium and zinc in women with second childbirth may be related to the increase in the number of births. Correlation analysis confirmed that calcium, lead and tin were significantly related to the growth of childbearing history . In addition, eating habits also affect the amount of mineral elements in the hair. Regular consumption of sauerkraut will lead to lower levels of zinc, iron, copper, manganese, strontium, but higher molybdenum, lead and selenium levels. Moreover, zinc and selenium levels increase as the frequency of meat intake increases. Regular intake of vegetables will increase the silicon content. At the same time, regular consumption of fruits increases the levels of manganese, nickel and titanium. Therefore, the study provides basic data and useful information for addressing reproductive and womens health in rural areas, which are prevailing in unbalanced diets.
