| 摘 要： | 通过盆栽实验,研究了胡萝卜、生菜、马铃薯、豌豆4种蔬菜在人工铀污染土壤中的种植情况。结果表明蔬菜吸收铀的能力不同,相同条件下的4种蔬菜可食用部位中铀含量大小顺序为:土豆>生菜叶>胡萝卜>豌豆;平均铀含量分别为:0.26,0.25,0.11,0.09 mg/kg,且均为低铀富集作物。加入铀溶液的土壤所种植的蔬菜样品中铀含量相比对照组土壤均有所升高,但其铀含量未超过国家标准限值,处于安全水平。

| Abstract: | Cultivation of carrot,lettuce,potato and pea in artificial uranium contaminated soil was studied under pot experiment condition.The results showed that different vegetables had different ability to absorb uranium.Under the same conditions,the order of uranium concentration in edible parts of four vegetables was potato,lettuce,carrot and pea,and the average uranium concentrations were 0.26,0.25,0.11,0.09 mg/kg,respectively.Four kinds of vegetables were all low uranium enriched crops.Compared with the concentrations of vegetables in control group,the concentrations of uranium in vegetables grown in artificial uranium contaminated soil increased,but all of them did not exceed the national standard limit. |
