遵义地区土壤元素含量与超标致癌元素的防治措施

Element Contents in Soil from the Region of Zunyi and Measures of Preventing and Controlling Carcinogenic Superscalar Elements

通过遵义地区各时代地层土壤中多种元素的含量分析、对比,划分出元素超标致癌的土壤地层,用种植物的方法提取各时代地层土壤中过量的致癌元素,减少过量的致癌元素在土壤中的残留,降低粮食、蔬菜中致癌元素的含量,或采用避让放射性元素过量的地层区域,提高区域内居民的寿命。

Analysis and comparison of the contents of a variety of elements in soil of the strata of different ages in the region Zunyi help us define the soil beds in which carcinogeneic elements are superscalar. By means of planting careinogenetic elements can be effectively extracted from soil of the strata of different ages, thus reducing the excess carcinogenetic elementsas residues in the soil. In this way the contents of carcinogenetie elements in cereals and vegetables can be effectively reduced. Or by adopting such a way as to avoid the strata and regions where radioactive elements are excessive, the local residents＇ longevity will be increased.
