摘要
本文研究了青藏高原东北部不同地区人群中血硒水平分布状况。研究表明:青海省人群血硒含量均值为0.075μg/ml(n=523),是正常均值的78.95%。全省有69.57%的地区属于低硒区、缺硒区和严重缺硒区;有84.73%的人群血硒水平低于正常值。6个民族血硒值依次为汉族>蒙古族>藏族>回族>撒拉族>土族。7种地理环境人群血硒含量分布,其顺序依次为城市>纯牧业区>半农半牧业区>农业区>州属农业区。为缺硒防治对策提供了科学依据。
The investigation of selenium content distribution in blood of crowds was analyzed in Qinghai province.The results showed that the average of blood selenium content in the crowds was 0.075μg/ml(n=523),which was 78.95%of the normal average.There are low selenium district, lack selenium district and serious lack selenium district in 69.57% area of the province;the blood selenium content is lower than normal value in 84.73% of the residents. The selenium level of the blood compared by the nationality as follows:Han>Meng>Tibetan> Hui> Sala>Tu.The concentration of the blood selenium of crowds in 5 geographical conditions are as follows:City>Animal husbandy>Farming and animal husbandy>Farming husbandy>Farming husbandy of poverth county. This paper provides scientific basis for prevntion and controlling in the lack selenium area.
