However, these uranium-accumulating plants may still release uranium back into the soil through decomposition, thereby increasing environmental risks. Currently, the decomposition characteristics and uranium release of uraniferous plants are still exploring. This study investigated the decomposition characteristics of uraniferous litter of Syngonium podophyllum in different parts and states, the migration and transformation patterns of uranium between litter and soil environment, and the effects of uraniferous litter decomposition on soil microbial communities. Results indicate that both litter decomposition rate and nutrient release rate of litter exhibited a similar pattern: an initial rapid release followed by a gradual decline in rates over time. The presence of uranium affects the decay and nutrient release of litter. Decomposition of uraniferous litter releases uranium into the soil, significantly increasing uranium bioactivity and bioavailability, posing substantial environmental threats. Concurrently, decomposition of uraniferous litter alters soil microbial communities, with dominant bacterial groups including Proteobacteria, Actinobacteria, Firmicutes, and Chloroflexi, while Ascomycota being predominant among fungi. This research provides a scientific theoretical basis and rationale for the phytoremediation practices of uranium-contaminated soils and the disposal management for uraniferous plants.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 9","pages":"6015 - 6027"},"PeriodicalIF":1.6,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CsMPs may locally increase radioactive cesium (RCs) concentration of soils and crops. Furthermore, RCs in the CsMPs is included in insoluble grassy particle, it is considered that it may be difficult for crops to absorb. Transfer factor (TF) is used to evaluate transfer of RCs from soils to crops. However, the conventional TF is a simple ratio of RCs concentrations between them. This suggests that conventional TF may not be able to accurately assess RCs transfer from soils to crops when CsMPs are in the soil. Since there are many contaminated forests in Fukushima Prefecture, Japan, there are concerns about secondary contamination due to the inflow of CsMPs. In this study, we investigated the deposition of CsMPs in the paddy field located within specified reconstruction and revitalization base area in the first year of resumed cultivation following the accident. Furthermore, we evaluate the impact of CsMPs on RCs concentration in the soil and TF of brown rice.The accumulation of RCs and CsMPs in our study field was not observed. RCs concentration of brown rice was less than the shipping limit defined by Japanese government. These suggested that the impact of secondary contamination was not large, and cultivation can be done safely. However, because there are many contaminated sites in the surrounding area, and it is necessary to continue to monitor the effects of radiation in the future. Furthermore, the proportion of CsMPs on RCs concentration in the soil was less than 10%. Therefore, CsMPs may not have a significant effect on transfer factor of RCs for brown rice.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 8","pages":"5719 - 5727"},"PeriodicalIF":1.6,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
