Soil-to-crop transfer of iodine-131 in cowpea (Vigna unguiculata (L.) Walp.), following factitious contaminations

摘要：

We studied the soil-to-crop transfer of <131>I in cowpea after factitious contamination of three texturally different soils with <131>I, ranging from 20 to 80kBq·kg<-1> in a pot experiment. The results showed that the <131>I accumulation in the plant tissues, uptake and transfer factors were all influenced by both the level of <131>I contamination and the texture of the soil. Uptake and TF were lowest in sandy clay loam and highest in loam. While the <131>I uptake by the crop showed a positive correlation, the TF were inversely related to the level of <131>I contamination. The TF varied from 0.1798 to 0.6387 (whole plant). More <131>I accumulation was observed in the stem than in the leaves and roots.
