福岛1号核电站放射性核素沉降一年后（正式名称为福岛第一核电站）2011年3月，放射性铯（134Cs，137 Cs）浓度（[Cs]）对2012年4月开始生长的99种野生植物进行了全面调查，其中大部分为一年生或夏季绿色多年生草本植物福岛县的稻田（3个研究点）和高地（1个研究点）。该调查在年内进行了三次（4月、7月和10月）。在每个站点，土壤（5厘米深的土芯）和植物（气生枝）被收集用于测定[Cs]的干重基础上，然后放射性铯从土壤到植物的转移因子（TF）（[Cs]植物/[Cs]土壤）估计在每个物种。土壤和植物的[Cs]值变化很大。然而，一些物种表现出相对较高的TF值（大于0.4）（例如，日本蕨、东京鳞毛蕨和短叶莎草），而其他植物表现出几乎可忽略的值（小于0.01）（例如，柳miyabeana，葎草，和Escherichus tsukushiensis）。此外，从11种在水、高地都生长的植物来看，TF值普遍在水田较高。稻田杂草群落对土壤放射性铯的植物提取效率的估算表明，杂草群落不是一种实用的植物修复技术。
One year after the deposition of radionuclides from the Fukushima 1 Nuclear Power Plant (A formal name is Fukushima Daiichi Nuclear Power Station) in March 2011, radiocesium (134Cs, 137Cs) concentrations ([Cs]) were comprehensively investigated in the wild plants of 99 species most of which were annual or summer green perennial herbs and started to grow from April 2012 at the heavily contaminated fields of paddy (three study sites) and upland (one study site) in Fukushima Prefecture. The survey was conducted three times (April, July and October) in the year. In each site, soils (soil cores of 5-cm depth) and plants (aerial shoots) were collected for determination of [Cs] on a dry weight basis, and then the transfer factor (TF) of radiocesium from soil to plant ([Cs]plant/[Cs]soil) was estimated in each species. The [Cs] values of both soils and plants largely varied. However, some species exhibited relatively high TF values (more than 0.4) (e.g., Athyrium yokoscense, Dryopteris tokyoensis, and Cyperus brevifolius), while others exhibited almost negligible values (less than 0.01) (e.g., Salix miyabeana, Humulus scandens, and Elymus tsukushiensis). In addition, judging from the 11 species grown in both paddy and upland fields, TF values were generally higher in the paddy fields. The estimation of phytoextraction efficiency of soil radiocesium by weed communities in the paddy fields suggests that the weed community is not a practical candidate for phytoremediation technique.
