Literature survey and analysis of phytoremediation strategies for Cs-137 decontamination

Phytoremediation has become a sustainable solution for mitigating cesium-137 (Cs-137) contamination and has been implemented in areas affected by the Chernobyl and Fukushima nuclear disasters. Despite the absence of nuclear power plants in Indonesia, incidents of Cs-137 contamination have been reported in Batan Indah Housing Complex, emphasizing the need for effective decontamination techniques. The aim of this study was to analyze the bibliometric characteristics of research works on phytoremediation in addressing Cs-137 contamination during the last ten years (2013–2022) by foreign and Indonesian authors. This research is important both globally and in specific contexts, such as Indonesia, particularly in the context of policy and practical applications. For example, when facing issues like Cs-137 decontamination in the BATAN Indah area, the research can have local relevance and contribute to solving immediate problems. This study utilized the Scopus database and retrieved 2,123 article titles within this topic over the last decade. Several indicators were used to examine the publications: productivity of authors, collaboration between countries, top-cited articles, keywords analysis, and publication trends. The results show that the number of publications fluctuated over previous decade with an average publications age of 5.54 years. Onda Y from the University of Tsukuba, Tsukuba, Japan become the most prolific and collaborative author. Japan being the most productive and collaborative country, while Indonesia ranked 42nd with only 9 publications regarding the topics. The bibliometric analysis provides a foundation for understanding the development of science on this topic and uncovers that there is still plenty of space to conduct phytoremediation research in Indonesia, especially for Cs-137 contaminated soils, which have increased over the years.
