铍的土壤背景值研究

本文介绍了我国土壤中铍的背景值结果。背景值含量范围为0.85~3.91mg/kg,算术均值为1.95mg/kg,几何均值为1.82mg/kg。呈近似对数正态分布。从土类分布趋势看,高山土较全国均值偏高,铁铝土较全国均值偏低。铍含量有随土壤中有机质含量增加而升高的趋势。湖南、甘肃,陕西及宁夏等省(自治区)内,因其进行过铍的冶炼或加工,可能已经造成不同程度的污染,有待进一步研究。 

The Study of Beryllium Element Background Value in Soil

The background value of Beryllium element in soil of China was studied. The content of Be in soil is approximately normal logarithmic, with the range from 0. 85 to 3.91 mg/kg, the arithmetic average of 1.95 mg/kg and the geometric average of i.82mg/kg. In consideration of the content of Be in various sort of soil, there is higher content in Alpine Great soil and lower in Allitic Great soil than the average. The content of Be increases with the organic content in soil. It needs to be further studied whether the soil is polluted by smelting or other industrial process of Beryllium with different extent in Hunan, Gansu and Shanxi Provinces and Ningxia Autonomous Region.
