锰是人体必需的微量元素,成人每天需要0.3～5mg锰,微量元素锰主要存在于食物中;一般豆类>面粉>谷类>蛋类。因此,研究食物中微量元素与人体健康是一项极有意义的工作。1988年我们对本省主要食品中天然放射性本底进行调查分析的同时,调查分析了食品中的微量元素锰,并根据1982年全国营养水平调查总结和我省食品构成统计资料的数据,分别推算了我省居民每天从食品中所摄取锰的贡献量。1 调查和实验方法 湖南省位于长江中游,西、南、东三面环山,地势逐渐向中,向东北倾象个大马蹄形盆地,居民主要以大米为主,水产品以淡水产品为主。
Manganese is an essential trace element of the human body, adults need 0.3 ~ 5mg manganese daily, trace elements manganese is mainly present in food; general beans> flour> cereals> eggs. Therefore, the study of trace elements in food and human health is a very meaningful work. In 1988, we investigated and analyzed the natural radioactive background of the main food in our province, and investigated and analyzed the trace elements manganese in food. Based on the survey of national nutrition level in 1982 and the statistical data of food composition in our province, Our province residents from the food intake of manganese daily contributions. 1 Investigation and experimental methods Hunan Province is located in the middle reaches of the Yangtze River. It is surrounded by mountains on three sides of the west, south and east. The terrain is gradually tilted to the middle and to the northeast as a large horseshoe-shaped basin. Residents are mainly dominated by rice. Freshwater products are the main products of aquatic products.
