(湘教通[2016]283号:序号:326):2016年度湖南省大学生研究性学习和创新性实验计划项目——×××(尾矿库)附近农作物铀和镉元素含量的测定与研究 (16C1363):湖南省教育厅项目

本校为第一机构

为评判中国南方A尾矿库附近植物的铀和镉元素含量是否符合＂食品中放射性物质限制浓度标准（GB14882-1994）＂和＂食品中污染物限值（GB2762-2012）＂的要求,从制定植物样品采集方案,现场采集植物样品,实验室处理样品,测定植物样品中铀和镉元素含量等方面开展了实验测量与初步研究工作。测量结果表明：尾矿库边界以东、南、西100m~800m范围内9个点植物样品中铀和镉元素含量测量结果范围分别位于1.14~1.48 mg/kg和0.15~0.19mg/kg,均大于或等于其对应的本底值0.24mg/kg和0.15mg/kg,小于GB14882和GB2762关于粮食和蔬菜类植物中铀和镉元素含量的浓度限值,此区域内种植粮食和蔬菜是安全的。尾矿库北面...

In order to judge whether or not the uranium and cadmium content of plants which is nearby A tailing pond in southern China meet the requirements of the concentration of radioactive material limited standard in food GB14882-1994 and the limited value in food GB2762-2012, the experimental measurement and preliminary research work are carried out from the aspects of making the sampling plan of the plant, collecting of plant samples on the spot, processing samples in laboratory, measuring uranium and cadmium content of plant and so on. Result shows that the measurement range of uranium and cadmiu...
