双流县位于成都市以南地区,平原丘陵兼半,主产水稻、小麦、油菜,丘陵兼种玉米、红苕、海椒、水果等农作物,平原交通发达,经济发展速度快,丘陵相对落后,两地居民经济状况、居住环境和饮食结构均存在较大差异,学生通过饮食、空气、外源物质摄入的微量元素和常量元素相应存在差异,测定头发中的微量元素是了解人体微量元素营养状况的一个重要方面,为此我们对本县平原、丘陵地区小学生头发中的18种元素进行测定,评价两地小学生微量元素营养状况。1 对象和方法1.1 随机抽取我县平原、丘陵地区各一所村小,8～13岁健康状况良好的小学生为对象,平原小学生58名,丘陵73名,共计131
Shuangliu County is located in the south of Chengdu City. With half of the plains and hills, it produces mainly crops such as rice, wheat, rapeseed and hills, maize, red seaweed, sea peppers and fruits. The plains have developed traffic, relatively fast economic development and relatively backward hills. Residents economic status, living environment and diet structure are quite different, the students through the diet, air, foreign material intake of trace elements and the corresponding elements of the corresponding discrepancies, the determination of trace elements in the hair is to understand the nutritional status of the human trace elements An important aspect, for which purpose, we measured the 18 elements in the hair of primary school students in the plain and hilly areas of the county, and evaluated the nutritional status of trace elements in pupils in both places. 1 objects and methods 1.1 randomly selected county plain, hilly area of a small village, 8 to 13-year-old healthy primary school students for the object, plain primary 58, 73 hills, a total of 131
